One embodiment of the present invention will be described below with reference to the drawings.

<1. Overall structure of the game system>
First, an example of the overall configuration of a game system 1 according to this embodiment will be described with reference to Fig. 1. As shown in Fig. 1, the game system 1 has an information processing device 3, a game controller 5, a display device 7, and a microphone 9. Each of the game controller 5, the display device 7, and the microphone 9 is connected to the information processing device 3 so as to be able to communicate with each other via wire or wirelessly.

The information processing device 3 is, for example, a stationary game machine. However, it is not limited to this, and may be, for example, a portable game machine that is equipped with an input unit, a display unit, etc. In addition to game machines, the information processing device 3 may be, for example, a server computer, a desktop computer, a notebook computer, a tablet computer, etc. that is manufactured and sold as a computer, or a smartphone, a mobile phone, a phablet, etc. that is manufactured and sold as a telephone.

The player uses the game controller 5 to perform various operational inputs. In the example shown in FIG. 1, the game controller 5 has, for example, a cross key 11 and a number of buttons 13. Note that the game controller 5 may have, for example, a joystick or a touch pad instead of or in addition to the above.

The microphone 9 is a voice input device that inputs voice uttered by the player. When the microphone 9 detects the voice of the player, it converts the voice into an electrical signal and transmits it to the information processing device 3. The microphone 9 may be provided as a standalone device as shown in FIG. 1, or may be provided integrally with either the information processing device 3, the game controller 5, or the display device 7.

2. Functional configuration of information processing device
Next, an example of a functional configuration of the information processing device 3 will be described with reference to FIG. 2 and FIG. 3 to FIG.

As shown in FIG. 2, the information processing device 3 has a command reception processing unit 15, a voice input processing unit 17, a text conversion processing unit 19, a command determination processing unit 21, a voice analysis processing unit 23, an algorithm change processing unit 25, a voice match determination processing unit 27, and a character control processing unit 29.

The command reception processing unit 15 receives commands input by the player. "Input" includes input made by the player operating the game controller 5 and voice input, which will be described later. "Commands" are instructions given by the player to the game, and include, for example, instructions to perform certain actions, actions, and in-game events (such as military councils, negotiations, marching into battle, using special moves, and changing formations, which will be described later), as well as detailed instructions given to the player character and other game characters during the execution of these actions.

The voice input processing unit 17 inputs the voice uttered by the player. As described above, the voice uttered by the player is converted into an electrical signal by the microphone 9, and the voice input processing unit 17 receives the electrical signal as a voice signal.

The text conversion processing unit 19 converts the voice input by the voice input processing unit 17 into the corresponding text (character string). Specifically, for example, the voice is analyzed by frequency analysis or the like, and phonemes are recognized using a voice recognition dictionary (acoustic model, language model, pronunciation dictionary, etc.), and then the voice is converted into text. Note that the processing by the text conversion processing unit 19 may use techniques such as machine learning and deep learning.

The command determination processing unit 21 determines the command that corresponds to the text converted by the text conversion processing unit 19. The determination method is not particularly limited, but for example, it determines whether or not the converted text contains a keyword related to a specific command, and if so, determines that it is the command. Keywords are set for each command and are registered in advance in a database (not shown).

The command reception processing unit 15 described above receives the commands determined by the command determination processing unit 21. This allows the player to input commands by voice. This makes it possible, for example, to give instructions while having a conversation with a game character.

The voice analysis processing unit 23 analyzes the volume and quality of the voice input by the voice input processing unit 17. "Volume" is the sound volume of the voice. "Voice quality" can be various elements such as the pitch, speed, brightness, resonance, tension, muddiness, fluency, smoothness, etc., but in this embodiment, voice quality is analyzed in terms of tone and speech, for example.

Figure 3 shows an example of the analysis content by the voice analysis processing unit 23. As shown in Figure 3, voice volume is classified into three types: "large," "medium," and "small" according to the volume. Voice volume is analyzed based on the magnitude of the amplitude of the received voice waveform.

Speech tone is classified into three types according to strength: "strong," "medium," and "weak." For example, if the voice volume is classified as "loud" and the speech rate is classified as "fast," the speech tone is classified as "strong." If the voice volume is classified as "medium" and the speech rate is classified as "medium," the speech tone is classified as "medium." If the voice volume is classified as "low" and the speech rate is classified as "slow," the speech tone is classified as "weak." Speech rate is analyzed based on the length of time one word is spoken, calculated by dividing the speech time of the received voice by the number of texts, for example, and classified into three types: "fast," "medium," and "slow."

Speech tones are classified into three types: "polite," "medium," and "rough." For example, if the vocal range is classified as "low" and the speech rate is classified as "slow," the speech tone is classified as "polite." If the vocal range is classified as "medium" and the speech rate is classified as "medium," the speech tone is classified as "medium." If the vocal range is classified as "high" and the speech rate is classified as "fast," the speech tone is classified as "rough." The vocal range is the pitch of the voice, and is analyzed, for example, based on the frequency of the received voice.

Note that the above analysis content is just an example, and each item may be classified into two or four or more types, or sound quality elements other than those listed above may be analyzed.

Returning to FIG. 2, the algorithm change processing unit 25 changes the algorithm that determines the game character's reaction to the command accepted by the command acceptance processing unit 15 from the default content based on the voice input by the voice input processing unit 17. That is, the algorithm change processing unit 25 changes the algorithm based on the volume or quality of the voice analyzed by the voice analysis processing unit 23. By changing the algorithm from the default content, changes occur in the game character's reaction, behavior, utterances, etc. to the command input by the player. This makes it possible to change the content of the game according to, for example, the volume, tone, and speech of the player's voice.

For example, the algorithm change processing unit 25 may change the algorithm based on the volume or quality of the voice analyzed by the voice analysis processing unit 23 and a personality parameter related to the personality of the game character. The "personality parameter" is not particularly limited as long as it is a parameter that represents the personality of the game character, but in this embodiment, as described below, obedience, which represents the obedience of the game character, passion, which represents enthusiasm, temperament, which represents strength of will, etc. are described as examples of personality parameters. Note that personality parameters other than these may also be used. In this way, the influence of the player's voice can be made to differ depending on the personality of the game character.

Figures 4 to 6 show specific examples of algorithm changes made by the algorithm change processing unit 25 in this case. Figure 4 shows an example in which, for example, a command is input by the player to execute a consultation in which multiple game characters participate. The consultation involves a player character (an example of a game character) operated by the player and one or more game characters (so-called non-player characters, an example of a game character) automatically controlled by a game program, and each character speaks to derive a conclusion, for example. The player inputs voice at the start of the consultation or at a specified timing during the consultation. In this case, the command input is made via the game controller 5, and the voice input for changing the algorithm may be specified separately by displaying the input timing on the game screen, and the player may make the voice in accordance with that. Alternatively, the command input may be made by voice, and the algorithm may be changed by analyzing the voice.

The algorithm change processing unit 25 changes the algorithm so that the content of the game character's remarks in the consultation changes based on the volume or quality of the voice. For example, in the example shown in FIG. 4, when the volume of the voice is "loud" and the obedience, which is a personality parameter of the game character, is "high", the game character, which was originally obedient, becomes more obedient under the influence of the loud voice of the player, and the algorithm changes so that the game character becomes more likely to comply with the player character's wishes. As a result, for example, the content of the game character's remarks in the consultation changes to one that agrees with the player character's remarks. On the other hand, when the volume of the voice is "loud" and the obedience, which is a personality parameter of the game character, is "low", the game character, which was originally not obedient, becomes more rebellious under the influence of the loud voice of the player, and the algorithm changes so that the game character becomes more likely to go against the player character's wishes. In this case, for example, the content of the game character's remarks in the consultation changes to one that opposes the player character's remarks.

In addition, if the volume of the voice of the player is "low" and the obedience, which is a personality parameter of the game character, is "high", the game character, who was originally obedient, is influenced by the voice of the player with a low voice volume and becomes more rebellious, and the algorithm changes so that the game character becomes more likely to go against the will of the player character. In this case, for example, the content of the remarks made by the game character in a discussion changes to something that opposes the remarks made by the player character. On the other hand, if the volume of the voice is "low" and the obedience, which is a personality parameter of the game character, is "low", the game character, who was originally not obedient, is influenced by the voice of the player with a low voice volume and becomes more obedient, and the algorithm changes so that the game character becomes more likely to go along with the will of the player character. As a result, for example, the content of the remarks made by the game character in a discussion changes to something that agrees with the remarks made by the player character.

Note that if the volume of the player's voice is "medium," the algorithm will not change from the default settings, regardless of the game character's personality, for example.

In the above, we have described a case where the content of a statement in a discussion changes based on the volume of the voice, but the algorithm may be changed so that the content changes based on the quality of the voice (tone, tone, etc.). Furthermore, the above process may be applied to general dialogue (conversation) between a player character and another game character, for example.

Figure 5 shows an example of a case where a command is input by the player regarding the execution of negotiations by the player character with another game character. Negotiations are carried out one-on-one, and are performed, for example, when persuading the other party in diplomacy, winning over an enemy character to your side, hiring personnel, or discussing a specific matter (price, etc.). The player inputs voice at the start of the negotiation or at a specific timing during the negotiation.

The algorithm change processing unit 25 changes the algorithm so that the success rate of negotiation changes based on the volume or quality of the voice. For example, in the example shown in FIG. 5, when the voice tone is "strong" and the passion, which is a personality parameter of the game character, is "high", the algorithm changes so that the game character, who was originally passionate and enthusiastic, becomes even more passionate under the influence of the player's strong voice, increasing the success rate of negotiation and making negotiation more likely to succeed. In this case, for example, the content of the game character's remarks in negotiations may be changed to content that agrees with the player character. On the other hand, when the voice tone is "strong" and the passion, which is a personality parameter of the game character, is "low", the algorithm changes so that the game character, who was originally less passionate and calm, rebels under the influence of the player's strong voice, decreasing the success rate of negotiation and making negotiation more likely to fail. In this case, for example, the content of the game character's remarks in negotiations may be changed to content that rebels against the player character.

In addition, when the tone of the voice of the player is "weak" and the passion, which is a personality parameter of the game character, is "high", the algorithm changes so that the game character, who was originally passionate and enthusiastic, is influenced by the weak voice of the player and instead rebels, decreasing the success rate of negotiations and making negotiations more likely to fail. In this case, for example, the content of the game character's remarks in negotiations may be changed to rebel against the player character. On the other hand, when the tone of the voice is "weak" and the passion, which is a personality parameter of the game character, is "low", the game character, who was originally less passionate and calm, is influenced by the weak voice of the player and instead becomes more passionate, increasing the success rate of negotiations and making negotiations more likely to succeed. In this case, for example, the content of the game character's remarks in negotiations may be changed to agree with the player character.

If the player's voice tone is "medium," the algorithm will not change from the default content, regardless of the personality of the opponent's game character, for example.

In the above, we have described a case where the success rate of negotiations changes based on the voice quality (tone of voice), but the algorithm may be changed so that it changes based on the volume of the voice.

Figure 6 shows an example of a case where, for example, a player inputs a command related to the participation of a group including multiple game characters, including the player character, in a specified in-game event. As an example of this case, a case will be described where an army (an example of a group) marches out to participate in a battle (an example of an in-game event). At the start of the march or at a specified timing during the march, the player inputs a voice.

The algorithm change processing unit 25 changes the algorithm so that the morale of the group changes based on the volume or quality of the voice. For example, in the example shown in FIG. 6, when the volume of the voice is "loud" and the temperament, which is the personality parameter of the army, is "calm", the army, which was originally calm and composed, is inspired by the loud voice of the player, and the algorithm changes so that the morale of the army rises. Note that the personality parameter of the army may be the personality parameter of the leader (e.g., a military commander or a military strategist) who commands the army, or the personality of the army may be a dominant personality based on the personality of each game character that constitutes the army. In addition, the personality parameter of the entire army may be set separately from the game characters that constitute the army. On the other hand, when the volume of the voice is "loud" and the temperament, which is the personality parameter of the army, is "rough", the algorithm changes so that the army, which was originally rough and volatile, rebels under the influence of the loud voice of the player, and the morale of the army falls.

Also, if the volume of the player's voice is "low" and the temperament, which is the personality parameter of the army, is "calm," the algorithm changes so that the army, which was originally calm and composed, loses motivation and morale drops under the influence of the player's low voice volume. On the other hand, if the volume of the voice is "low" and the temperament, which is the personality parameter of the army, is "fierce," the algorithm changes so that the army, which was originally fierce and volatile, spontaneously becomes motivated and morale rises under the influence of the player's low voice volume.

Note that if the player's voice volume is set to "medium," the algorithm will not change from the default settings, regardless of the military's characteristics, for example.

The effect of increasing or decreasing morale only lasts for a certain period of time, and can be returned to normal after a certain period of time has passed. Increasing morale increases the offensive and defensive power of the army, while decreasing morale decreases the offensive and defensive power of the army (the so-called buff and debuff effects).

In the above, we have described a case where the morale of the army changes based on the volume of the voice, but the algorithm may be changed so that it changes based on the quality of the voice (tone, tone, etc.). Also, the army marching out as described above is just one example, and the invention may be applied to a wide variety of situations in which a group including multiple game characters participates in a specified in-game event, such as a group including a player character participating in an audition.

Returning to FIG. 2, the algorithm change processing unit 25 may change the algorithm so that ability parameters related to the abilities of the game character change based on the volume or quality of the voice analyzed by the voice analysis processing unit 23. The "ability parameters" are not particularly limited as long as they are parameters that represent the abilities of the game character, and may be, for example, attack power, defense power, wisdom, speed, etc. Note that ability parameters other than these may also be changed. This makes it possible to change the abilities of the game character according to the volume, tone, and speech tone of the voice uttered by the player.

The voice match determination processing unit 27 also displays on the display device 7 a character string that the player is to pronounce at a predetermined timing, and determines whether the text input by the voice input processing unit 17 and converted by the text conversion processing unit 19 in response to this is the correct pronunciation. The algorithm change processing unit 25 changes the algorithm based on the result of the determination by the voice match determination processing unit 27. This makes it possible to change the content of the game depending on whether the player was able to pronounce the character string displayed on the display device 7 correctly.

Figures 7 to 9 show specific examples of algorithm changes made by the algorithm change processing unit 25 in this case. Figure 7 shows an example in which, for example, a command related to the activation of a special move is input by the player. The special move may be a move activated by the player character alone, or may be a move activated by the player character together with one or more allied game characters.

Figure 8 shows an example of a screen for displaying a special move. In the example shown in Figure 8, the player character 31 alone is performing a special move called "Goki Shoten", and the name of the special move is displayed in the text display section 33. As shown in Figure 7, if the voice produced by the player in response to this does not match the reading of the special move "Goki Shoten" and the reading is incorrect, the algorithm change processing section 25 changes the algorithm so that the special move is not performed. In this case, for example, a special move other than "Goki Shoten" may be performed, or instead of being unable to perform the special move, the player may perform a normal attack, encourage a teammate (causing a buff effect on the teammate), or take other action.

On the other hand, if the voice made by the player matches the reading of the special move, the algorithm change processing unit 25 changes the algorithm so that the effectiveness of the special move changes based on the volume or quality of the voice. For example, as shown in FIG. 7, the algorithm changes so that when the volume of the voice is "loud," the effectiveness of the special move increases, when the volume of the voice is "medium," the effectiveness of the special move does not change, and when the volume of the voice is "low," the effectiveness of the special move decreases.

In the above, we have described a case where the effectiveness of a special move changes based on the volume of the voice, but the algorithm may be changed so that it changes based on the quality of the voice (tone, tone, etc.). Also, the above processing is not limited to special moves, and may be applied to normal attacks, use of items, activation of skills, etc., for example.

Figure 9 shows an example of a case where a command relating to a change in formation is input by the player. This process is effective in a game system where time progresses in real time and where a concept of time is set for the actions of game characters, and it is possible to change the execution speed of an action according to the volume and quality of the voice uttered by the player. As an example, a case where the player's army changes formation during battle will be explained. The player inputs voice at the timing to start changing the formation or at a specified timing during the change.

The algorithm change processing unit 25 changes the algorithm so that the speed at which an action is performed changes based on the volume or quality of the voice. For example, in the example shown in FIG. 9, if the tone of the voice is "polite" and the military's personality parameter obedience is "high", the army, which was originally obedient, becomes more obedient under the influence of the player's polite tone of voice, and the algorithm changes so that the speed at which the formation change is performed increases. On the other hand, if the tone of the voice is "polite" and the military's personality parameter obedience is "low", the army, which was originally not obedient, becomes more rebellious under the influence of the player's polite tone of voice, and the algorithm changes so that the speed at which the formation change is performed decreases.

Also, if the tone of the player's voice is "rough" and the army's personality parameter obedience is "high", the army, which was originally obedient, will be influenced by the player's rough tone of voice and will instead become more rebellious, and the algorithm will change to slow down the execution speed of the formation change. On the other hand, if the tone of the voice is "rough" and the army's personality parameter obedience is "low", the army, which was originally not obedient, will be influenced by the player's rough tone of voice and will instead become more obedient, and the algorithm will change to speed up the execution speed of the formation change.

Note that if the player's voice tone is "medium," the algorithm will not change from the default, regardless of the military's characteristics, for example.

In the above, we have described a case where the execution speed of the formation change changes based on the voice quality (tone of voice), but the algorithm may be changed so that it changes based on the volume of the voice. Also, the above-mentioned formation change speed is just one example, and it can be applied to a wide variety of situations as long as it is an execution speed related to an action that has a time concept set, such as the movement speed of a game character, the activation speed of an attack, skill, item, or special move, etc.

Returning to FIG. 2, the character control processing unit 29 controls the player character or other game characters based on the algorithm changed in the above manner.

The processing in each processing unit described above is not limited to these examples of division of processing, and may be performed by a smaller number of processing units (e.g., one processing unit), or may be performed by a further subdivided processing unit. The functions of each processing unit described above are implemented by a game program executed by the CPU 101 (see FIG. 14 described below), but some of them may be implemented by actual devices such as dedicated integrated circuits such as ASICs and FPGAs, or other electrical circuits.

3. Processing procedure executed by the information processing device
Next, an example of a processing procedure executed by the CPU 101 of the information processing device 3 will be described with reference to FIG.

As shown in FIG. 10, in step S10, the information processing device 3 determines, via the command reception processing unit 15, whether or not a command input by the player has been received. As described above, command input includes input made by operating the game controller 5 and input by voice. This step S10 is repeated until a command is received (step S10: NO), and if a command is received (step S10: YES), the process proceeds to step S20.

In step S20, the information processing device 3 inputs the voice uttered by the player through the voice input processing unit 17. As described above, the voice may be input by specifying the input timing by displaying it on the game screen, etc., and having the player utter a voice in accordance with that timing. Note that if the command input in step S10 is performed by voice, step S20 may be omitted.

In step S25, the information processing device 3 converts the voice input in step S20 into a corresponding text (character string) by frequency analysis or the like using the text conversion processing unit 19, and analyzes and determines the content of the voice. In addition, the command determination processing unit 21 determines the command that corresponds to the converted text, and executes processing corresponding to the determined command as necessary.

In step S30, the information processing device 3 uses the voice analysis processing unit 23 to analyze the volume or quality of the voice input in step S20.

In step S40, the information processing device 3 causes the algorithm change processing unit 25 to change the algorithm that determines the reaction of the player character or other game characters to the command received in step S10 or the command determined in step S25 from the default content based on the analysis result in step S30.

In step S50, the information processing device 3 controls the player character or another game character based on the algorithm changed in step S40 above, using the character control processing unit 29. This ends this flowchart.

The above-mentioned processing steps are merely examples, and at least some of the steps may be deleted or modified, or steps other than those described above may be added. In addition, the order of at least some of the steps may be changed, or multiple steps may be combined into a single step.

4. Effects of the embodiment
The game program of this embodiment causes the information processing device 3 to function as a command reception processing unit 15 that receives commands input by the player, a voice input processing unit 17 that inputs voice uttered by the player, an algorithm change processing unit 25 that changes the algorithm that determines the reaction of the game character to commands based on the input voice, and a character control processing unit 29 that controls the game character based on the changed algorithm.

When executing a command input by the player, the game program of this embodiment changes the algorithm that determines the game character's response to the command based on the voice uttered by the player. This allows the content of the game to be changed according to the player's voice, improving entertainment value. Furthermore, by uttering sounds during gameplay, it is possible to increase the sense of immersion and realism in the game space, and the sense of oneness with the game character.

In particular, in this embodiment, the game program causes the information processing device 3 to further function as a text conversion processing unit 19 that converts input voice into text, and a command determination processing unit 21 that determines the command that corresponds to the converted text, and the command reception processing unit 15 receives the determined command.

This allows the player to input commands by voice. As a result, it becomes possible, for example, to give instructions while conversing with a game character. As commands are input by voice, the content of the game can be changed in response to that voice. By enabling voice control in this way, it is possible to further enhance the sense of immersion and realism in the game space, and the sense of oneness with the game character.

In particular, in this embodiment, the game program causes the information processing device 3 to further function as a voice analysis processing unit 23 that analyzes the volume or voice quality of the input voice, and the algorithm change processing unit 25 changes the algorithm based on the volume or voice quality of the analyzed voice.

This allows the algorithm to be finely adjusted according to the volume and quality of the player's voice, further increasing the interest of the game.

In particular, in this embodiment, the algorithm change processing unit 25 changes the algorithm based on the volume or quality of the voice and personality parameters related to the personality of the game character.

This allows the influence of the player's voice to differ depending on the personality of the game character. For example, when a player character negotiates with another game character, if the negotiating partner is a timid character, the player can make the negotiation more likely to succeed by speaking louder or with a stronger tone. On the other hand, if the negotiating partner is, for example, a calm and collected character, speaking louder or with a stronger tone can have the opposite effect and make the negotiation more likely to fail. In this way, the player needs to take into account the personality of the other game character when speaking in order to advance the negotiation to his or her advantage. This increases the level of strategy and improves the game's interest.

In particular, in this embodiment, the algorithm change processing unit 25 changes the algorithm so that the ability parameters related to the game character's abilities change based on the volume or quality of the voice.

This allows the ability of the game character to be changed according to the volume and quality of the voice uttered by the player. For example, in a battle, when the player character activates a special move, if the player's voice volume is loud, the effectiveness of the special move can be increased. On the other hand, if the player's voice volume is quiet, the effectiveness of the special move can be weakened. In addition to this, it is also possible to vary the effectiveness of the special move according to the personality of the player character and enemy character, for example, by encouraging a passionate player character with a loud voice to increase the attacking power, or by intimidating a timid enemy character with a strong voice to weaken the defensive power. In this way, the player needs to utter words taking into consideration various factors such as the personality of the player character and enemy character in order to gain an advantage in the battle. This increases the strategic nature of the game and improves the game's interest.

In particular, in this embodiment, when a command related to the execution of a conference in which multiple game characters participate is input by the player, the algorithm change processing unit 25 changes the algorithm so that the content of the remarks made by the game characters in the conference changes based on the volume or quality of the voice.

This allows the content of the consultation to be changed according to the volume and quality of the voice uttered by the player. For example, in a consultation in which a player character participates, if the player speaks loudly or in a strong tone, the words of the other game characters are more likely to follow the player character's wishes, whereas if the player speaks quietly or in a weak tone, the words of the other game characters are more likely to go against the player character's wishes. In addition to this, it is also possible to vary the content of the consultation according to the personality of the other game characters. In this way, the player needs to speak while taking into consideration various factors such as the personality of the other game characters in order to advance the consultation in a way that suits the player's wishes. This increases the level of strategy and improves the interest.

In particular, in this embodiment, when a command related to executing negotiations with a game character is input by the player, the algorithm change processing unit 25 changes the algorithm so that the success rate of the negotiation changes based on the volume or quality of the voice.

This makes it possible to change the success or failure of negotiations depending on the volume and quality of the voice uttered by the player. For example, in negotiations between a player character and another game character, if the player's voice is strong and polite, the negotiation is more likely to succeed, whereas if the player's voice is weak and rough, the negotiation is more likely to fail. In addition to this, it is also possible to vary the way in which the success rate changes depending on the personality of the other game character. In this way, in order to advance negotiations advantageously, the player needs to utter words taking into consideration various factors such as the personality of the other game character. This increases the strategic nature of the negotiations and improves the interest.

In particular, in this embodiment, when a player inputs a command related to participation of a group including multiple game characters in a specified in-game event, the algorithm change processing unit 25 changes the algorithm so that the morale of the group changes based on the volume or quality of the voice.

This makes it possible to change the morale of the group depending on the volume and quality of the voice uttered by the player. For example, when an army led by a player character marches into battle, if the player speaks loudly or in a strong tone, the morale of the army will rise, whereas if the player speaks quietly or in a weak tone, the morale of the army will fall. In addition to this, it is also possible to vary the way morale changes depending on the personality of the army or the game characters that make up the army. In this way, in order to raise the morale of the army, the player needs to make sounds taking into consideration various factors such as the personality of the army or the game characters that make up the army. This increases the strategic element and improves the interest.

In particular, in this embodiment, when the player inputs a command related to the activation of a special move by a game character, the algorithm change processing unit 25 changes the algorithm so that the effectiveness of the special move changes based on the volume or quality of the voice.

This allows the effect of the special move to be changed according to the volume and quality of the voice uttered by the player. For example, when the player character activates a special move, if the player speaks loudly, the effect becomes stronger, whereas if the player speaks quietly, the effect becomes weaker. This allows the player to speak while the special move is being activated, thereby further enhancing the sense of immersion and realism in the game space, and the sense of unity with the game character. In this case, the way in which the effect of the special move changes may be varied depending on, for example, whether the name of the special move is displayed and the player can pronounce it correctly. In this case, the player does not simply need to speak loudly, but is also required to pronounce the name of the special move accurately. Therefore, by applying this to cases where the name of the special move is difficult to pronounce, for example, the interest of the game can be improved.

In particular, in this embodiment, when a player inputs a command to perform an action that requires a certain amount of time in a game in which time progresses in real time, the algorithm change processing unit 25 changes the algorithm so that the speed at which the action is performed changes based on the volume or quality of the voice.

The present technical content is effective in the case of a game system in which time progresses in real time. That is, according to the present technical content, the execution speed of the action of the game character can be changed according to the volume and quality of the voice uttered by the player. For example, when the player's army changes the formation during a battle, if the player's voice volume is loud or the tone is polite, the speed of the change of the formation will be faster (the time required for the change will be shorter), whereas if the player's voice volume is low or the tone is rough, the speed of the change will be slower (the time required for the change will be longer). In addition to these, it is also possible to vary the speed of the change of the formation according to the personality of the army or the game characters that make up the army. If a unique effect is set for each formation and the effect is not exerted and the ability is reduced while the formation is being changed, the player needs to change the formation in a short time at a timing according to the tactics. Therefore, in order to change the formation in a short time, the player needs to speak while taking into consideration various factors such as the personality of the army or the game characters that make up the army. Therefore, the strategy can be increased and the interest can be improved.

5. Modifications, etc.
The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit and technical concept of the present invention.

(5-1. Changing the algorithm based on machine learning)
The above describes a case where the volume and quality of the voice uttered by the player are analyzed by a program. However, in addition to the tone and speech tone, the quality of the voice also includes various elements that are difficult to quantify, such as brightness, resonance, tension, muddiness, fluency, and smoothness. It is very laborious and difficult to program the correlation between these elements and the changes in the algorithm by specifying them one by one.

For example, a learning data set may be prepared that associates various types of voice with changes in the algorithm, and a machine learning process based on the learning data set may be executed to allow the algorithm change processing unit to learn the correlation between the volume and quality of the voice and the changes in the algorithm. In this modified example, the algorithm change processing unit changes the algorithm based on the correlation.

Figure 11 shows an example of the functional configuration of an information processing device 3A of this modified example. As shown in Figure 11, the information processing device 3A omits the voice analysis processing unit 23 in the functional configuration of the information processing device 3 described above, and has an algorithm change processing unit 35 instead of the algorithm change processing unit 25. The other functional configurations are the same as those in Figure 2 described above.

The algorithm change processing unit 35 changes the algorithm based on the correlation between the input voice, the volume or quality of the voice learned by the machine learning process, and the changes in the algorithm.

The above machine learning executed in the algorithm change processing unit 35 can apply various known learning methods. Below, as an example, a case where deep learning is applied to a machine learning algorithm is described. FIG. 12 shows an example of a model configuration of a neural network of the algorithm change processing unit 35 when deep learning is applied. Note that the example shown in FIG. 12 is a case where the algorithm is changed so that the ability parameters of a game character change.

In FIG. 12, the neural network of the algorithm change processing unit 35 is designed to output changed ability parameters (e.g., attack, leadership, wisdom) estimated from the correspondence between the voice input by the voice input processing unit 17, the game character's personality parameters (e.g., passion, obedience, temperament) obtained from a database or the like, and the game character's default ability parameters (e.g., attack, leadership, wisdom).

As shown in FIG. 12, each element of the voice data (volume, voice quality, etc.) and each game character's personality parameters and ability parameters are input to each input node of the algorithm change processing unit 35. Then, each output node outputs the changed ability parameters. The output contents of these changed ability parameters are based on the learning contents in the machine learning process of the algorithm change processing unit 35. That is, in the neural network of the algorithm change processing unit 35, features that represent the correlation between the voice volume or voice quality and the changes in the algorithm (in this example, the changes in the ability parameters) are learned.

In the machine learning process of the algorithm change processing unit 35, the multilayer neural network designed as described above can be implemented in software (or hardware) in the information processing device 3, and then can be trained by so-called supervised learning using a large number of training data sets stored, for example, in a database (not shown).

The learning dataset is a dataset that associates voice waveform data, personality parameters, and default ability parameters generated at various voice volumes or voice qualities with provisionally set changed ability parameters, as shown in FIG. 13, for example.

Then, using the combined teacher data in which the voice waveform data, personality parameters, and default ability parameters are used as input data and the changed ability parameters are used as output data, learning can be performed by a so-called backpropagation process or the like, which adjusts the weight coefficients of the edges connecting the nodes so that a relationship is established between the input layer and output layer of the neural network of the algorithm change processing unit 35.

The machine learning algorithm executed by the algorithm change processing unit 35 is not limited to the above-mentioned deep learning algorithm, and other machine learning algorithms using, for example, a support vector machine or a Bayesian network may be applied. Even in such cases, the basic configuration of outputting changed ability parameters that appropriately correspond to the input voice waveform data, personality parameters, and predefined ability parameters remains the same.

Note that while machine learning has been applied to changing ability parameters in the above, it may also be applied to changing algorithms to change the way a game character responds to commands, such as by changing their speech and behavior.

According to the modified example described above, the algorithm change processing unit 35 changes the algorithm based on the correlation between the input voice, the volume or quality of the voice learned by the machine learning process, and the changes in the algorithm. This makes it possible to change the algorithm in detail according to the volume and quality of the voice without specifying various elements of the voice.

(5-2. Other)
The game described above can also be applied to an online game. In this case, the information processing device 3 is connected to a server device via the Internet, for example, and the server device is provided with part or all of the functional configuration of the information processing device 3, 3A shown in Fig. 2 or Fig. 11 described above. In this case, the server device corresponds to an example of the information processing device.

Although no particular mention has been made above about the types of player characters operated by the player or other game characters, they may be characters other than human characters (such as military commanders and strategists, both male and female). For example, they may be animals other than humans, creatures other than humans and animals, virtual creatures (such as monsters, ghosts, spirits, etc.), robots, objects such as goods and objects, etc.

Although no particular reference has been made above to the types of games to which the present invention can be applied, the present invention can be applied to various types of games. For example, the present invention can be applied to any genre of game, including Sengoku simulation games, other simulation games, role-playing games, adventure games, horror games, romance games, puzzle games, and competitive games such as sports.

In addition to what has already been described above, the methods according to the above embodiments and each modified example may be used in appropriate combinations. In addition, although not shown individually, the above embodiments and each modified example may be implemented with various modifications within the scope of their intent.

6. Hardware configuration of information processing device
Next, an example of a hardware configuration of the information processing device 3 that realizes each processing unit implemented by the program executed by the CPU 101 etc. described above will be described with reference to FIG.

As shown in FIG. 14, the information processing device 3 has, for example, a CPU 101, a ROM 103, a RAM 105, a GPU 106, a dedicated integrated circuit 107 constructed for a specific application, such as an ASIC or FPGA, an input device 113, an output device 115, a recording device 117, a drive 119, a connection port 121, and a communication device 123. These components are connected to each other via a bus 109, an input/output interface 111, etc., so that signals can be transmitted between them.

The game program can be recorded, for example, in ROM 103, RAM 105, or a recording device 117 such as a hard disk.

The game program may also be temporarily or permanently (non-temporarily) recorded on a removable recording medium 125, such as a magnetic disk such as a flexible disk, various types of CDs, MO disks, optical disks such as DVDs, or semiconductor memory. Such recording media 125 may also be provided as so-called packaged software. In this case, the game program recorded on these recording media 125 may be read by the drive 119 and recorded on the recording device 117 via the input/output interface 111, bus 109, etc.

The game program may also be recorded, for example, on a download site, another computer, or another recording device (not shown). In this case, the game program is transferred via a network NW such as a LAN or the Internet, and the communication device 123 receives this program. The program received by the communication device 123 may then be recorded in the recording device 117 via the input/output interface 111, the bus 109, etc.

The game program may also be recorded, for example, in an appropriate external connection device 127. In this case, the game program may be transferred via an appropriate connection port 121 and recorded in the recording device 117 via the input/output interface 111, bus 109, etc.

Then, the CPU 101 executes various processes according to the programs recorded in the recording device 117, thereby realizing processes by the command reception processing unit 15, voice input processing unit 17, text conversion processing unit 19, command determination processing unit 21, voice analysis processing unit 23, algorithm change processing unit 25, voice match determination processing unit 27, character control processing unit 29, etc. described above. At this time, the CPU 101 may, for example, read and execute the programs directly from the recording device 117, or may execute the programs after first loading them into the RAM 105. Furthermore, when the CPU 101 receives a program via the communication device 123, drive 119, or connection port 121, for example, it may execute the received program directly without recording it in the recording device 117.

In addition, the CPU 101 may perform various processes based on signals and information input from an input device 113, such as a mouse, keyboard, etc. (not shown), including the aforementioned game controller 5 and microphone 9, as necessary.

The GPU 106 performs image display processing, such as rendering processing, in response to instructions from the CPU 101.

Then, the CPU 101 and the GPU 106 output the results of the above-mentioned processing from the output device 115, which may include, for example, the display device 7 mentioned above. Furthermore, the CPU 101 and the GPU 106 may transmit the results of this processing via the communication device 123 or the connection port 121 as necessary, or may record the results in the recording device 117 or the recording medium 125 mentioned above.
