Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication system in which a calling terminal and a called terminal called by the calling terminal communicate with each other.
[0002]
[Prior art]
Conventionally, when communication between communication devices is to be started, it is common to specify a communication destination address of a called terminal to be a communication partner at the calling terminal.
For example, in the case of communication by telephone, an input operation of a telephone number which is a communication destination address of a called telephone is usually performed on the calling telephone. And recently, even if you do not perform such phone number input operation, just calling the name of the person you want to call to the telephone, the call operation to the telephone of the other party is automatically performed Is also known. In a telephone having such a function, the name of each telephone user and the telephone number of the telephone can be registered as information on a plurality of telephones as communication destination candidates. When the name of the other party who wants to make a call is issued by the user of the telephone, the name is identified by analyzing the voice, and the call is made to the telephone number stored corresponding to the name. I do. Therefore, the user of such a telephone does not need to perform a troublesome operation such as inputting a telephone number, and does not have to bother to remember the other party's telephone number.
[0003]
[Problems to be solved by the invention]
By the way, the present inventor considered to apply the technique as described above, that is, a technique for starting communication with a desired communication device by voice to other communications. For example, a communication destination address used for communication by Bluetooth, TCP / IP, or the like is more complicated than the above-described telephone number, and is less likely to be remembered by the user. Therefore, the effect of using such a technique is high.
[0004]
However, in a communication system composed of a plurality of communication devices, information on communication devices that are candidates for communication destinations (that is, identification names and communication destination addresses of communication devices) for all communication devices that can be caller terminals. Must be registered in the communication system as a whole, information about a certain communication device X is registered redundantly in all communication devices that can be called terminals. There is a problem that information to be registered in the communication device is increased.
[0005]
For example, in a communication system comprising a plurality of communication devices that function as both a calling side terminal and a called side terminal, all communication devices can be calling side terminals. It is necessary to store information about other communication devices. For this reason, as the number of communication devices constituting the communication system increases, the amount of information to be registered in each communication device also increases.
[0006]
The present invention has been made in view of these problems, and an object of the present invention is to reduce information to be registered in a communication device in a communication system in which communication with a desired communication device is started by voice.
[0007]
[Means for Solving the Problems and Effects of the Invention]
The communication system according to claim 1, which has been made to achieve the above object, is called by a calling terminal among a calling terminal and a plurality of called terminals communicable with the calling terminal. Communication with the called terminal is performed.
[0008]
In the present communication system, the calling side terminal is provided with a calling side input means for inputting voice, and the calling judgment means sends the voice input by the calling side input means to the calling side terminal. If it is determined whether or not the voice represents the identification name, and the call determination means determines that the voice represents the identification name of the called terminal, the transmission means Is transmitted to a plurality of called terminals communicable with the calling terminal as identification name information of the called terminal that the calling terminal wants to call. Note that the data representing the content of the voice may be, for example, data representing the voice itself, or may be data obtained by converting the voice content into text data.
[0009]
On the other hand, the called terminal is provided with storage means for storing the identification name of the called terminal, and the called determination means receives the identification name information transmitted by the transmitting means of the calling terminal. And determining whether the identification name represented by the identification name information and the identification name stored by the storage means are the same, and if the called determination means determines that they are the same, the communication start means However, processing for starting communication using the calling side input means of the calling side terminal is performed. The communication using the calling side input means of the calling side terminal is a communication in which the content of the voice uttered by the user of the calling side terminal is transmitted to the user of the called side terminal. is there.
[0010]
In other words, in the communication system according to claim 1, the user of the calling side terminal sets the identification name of the called side terminal (for example, the name of the user of the called side terminal) to be the communication destination to the calling side terminal. When calling, the calling terminal transmits identification name information, which is data representing the contents of the voice, to a plurality of called terminals that can communicate with the calling terminal regardless of the identification name represented by the voice. Then, each called terminal that receives the identification name information determines whether or not the identification name information is for calling the called terminal.
[0011]
According to such a communication system of claim 1, it is only necessary that each called-side terminal has the registered name of the called-side terminal registered. The total amount of information to be registered can be reduced, so that the information to be stored in each communication device can be reduced.
[0012]
Therefore, for example, even in a communication system including a plurality of communication devices that function as both a calling side terminal and a called side terminal, all the communication devices need only store the identification name of the communication device. Even if the number of communication devices constituting the communication system increases, the amount of information to be registered in each communication device does not increase.
[0013]
By the way, when a voice representing a predetermined start keyword is input by the calling side input unit, the calling determination unit of the calling side terminal is input next to the keyword, for example, as in claim 2. It may be determined that the voice represents the identification name of the called terminal. According to this configuration, it is possible to easily determine whether or not the input voice is the identification name of the called terminal.
[0014]
Next, in the communication system according to the third aspect, the calling side terminal includes a calling side communication ending unit, and the calling side communication ending unit is connected to the predetermined calling side by the calling side input unit. When a voice representing an end keyword is input, a process for ending communication with the called terminal is performed. According to this configuration, the user of the calling terminal can not only start and communicate with the called terminal, but can also terminate the communication by voice, and as a result, communicates hands-free. It can be performed.
[0015]
On the other hand, in the communication system according to claim 4, the called-side terminal includes a called-side input unit for inputting voice and a called-side communication end unit, and the called-side communication end unit includes: When a voice representing a predetermined callee end keyword is input from the callee input means, a process for ending communication with the callee terminal is performed. According to this configuration, the user of the called terminal can end communication by voice.
[0016]
Next, in the communication system according to the fifth aspect, the called terminal includes a called side input means for inputting voice, a registration determination means, and an identification name registration means. Then, the registration judging means judges whether or not the voice inputted by the called side input means represents a word to be registered as the identification name of the called side terminal, and the voice is inputted by the registration judging means. When it is determined that the name to be registered as the identification name of the called terminal is the identification name registration means, the word represented by the voice is stored in the storage means as the identification name of the called terminal. Remember as. According to this configuration, the user of the called terminal can register the identification name of the called terminal by voice, and can eliminate the troublesome registration operation.
[0017]
Next, in the communication system according to claim 6, the called terminal includes notification means, and when the notification means performs processing for starting communication by the communication start means, Informs the owner of the call terminal. According to this configuration, it is possible to notify the user of the called terminal that there is a call from the calling terminal, and the user of the called terminal can communicate with the calling terminal without noticing. It is possible to prevent communication from being started.
[0018]
Next, the communication device according to claim 7 is a called-side terminal called by the calling-side terminal among the calling-side terminal and a plurality of called-side terminals communicable with the calling-side terminal. In a communication system configured to start communication when the called terminal transmits identification name information representing the called terminal from the calling terminal. It is used as a side terminal. The communication device is provided with input means for inputting voice, and the call determination means determines whether the voice input by the input means represents the identification name of the called terminal. If the call determining means determines that the voice represents the identification name of the called terminal, the transmitting means calls the data representing the contents of the voice to be called by the communication device. The identification name information of the call side terminal is transmitted to a plurality of called side terminals that can communicate with the communication device. And according to this communication apparatus, the communication system which can acquire the effect similar to the system of the said Claim 1 can be constructed | assembled.
[0019]
Next, the communication device according to claim 8 is a called-side terminal called by the calling-side terminal among the calling-side terminal and a plurality of called-side terminals communicable with the calling-side terminal. Are used as called terminals in a communication system that performs communication. The communication device is provided with storage means for storing the identification name of the communication device, and the call determining means is information transmitted from the calling terminal to a plurality of called terminals. The identification name information indicating the identification name of the called terminal that the calling terminal wants to call is received, and whether or not the identification name represented by the identification name information and the identification name stored by the storage means are the same If it is determined that the same is determined by the called determination unit, the communication start unit performs processing for starting communication with the calling terminal. And according to this communication apparatus, the communication system which can acquire the effect similar to the system of the said Claim 1 can be constructed | assembled.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments to which the present invention is applied will be described below with reference to the drawings.
First, FIG. 1 is an explanatory diagram illustrating a configuration of a communication system according to an embodiment.
This communication system is composed of a plurality of headsets 10 which are communication devices that perform Bluetooth wireless communication.
[0021]
Here, although well known, Bluetooth wireless communication will be briefly described.
The Bluetooth communication is a wireless transmission method using a 2.4 GHz band, and each communication device has a 48-bit BD address (Bluetooth Device address) as unique information. The communication area for Bluetooth communication is about 10 to 100 [m], although it varies depending on the class of transmission output. The headset 10 used in the communication system can communicate with another headset 10 existing in a communication area (piconet area) 2 having a radius of about 100 m.
[0022]
In the communication system shown in FIG. 1, the user of each headset 10 performs voice communication (conversation) with the user of the desired headset 10 existing in the communication area 2 of the headset 10. It can be started by issuing the user's name. In the communication system, each headset 10 has the same function.
[0023]
FIG. 2 is an external view of the headset 10.
As shown in FIG. 2, the headset 10 is provided with a bendable arm 14 with an antenna 12 built in, and both ends of the arm 14, and the headset 10 is mounted on the user's head. Pads 16 and 16 located in the ear portion and a rod 20 extending from one pad 16 and positioning the tip microphone 18 at the mouth of the user are provided. The pads 16 and 16 are provided with speakers 22 and 22, respectively.
[0024]
On the other hand, FIG. 3 is a block diagram showing the internal configuration of the headset 10.
As shown in FIG. 3, the headset 10 includes a Bluetooth module 24 that transmits and receives data by Bluetooth wireless communication via an antenna 12, and an audio analog signal generated by inputting sound from the microphone 18 ( A voice CODEC 26 that performs a process of converting the voice signal) into voice digital data (voice data), a process of converting the voice data into a voice signal and outputting the voice signal from the speaker 22, and analyzing the voice data to obtain the voice data A voice recognition device (Voice Recognition) 28 that generates character string data, which is data of a character string to be represented, an NVRAM 30 as a nonvolatile memory capable of rewriting data, and a well-known CPU 32, RAM 34, and ROM 36 are provided. In the above-described configuration, it goes without saying that the same processing is performed for sounds other than voice (sound emitted from a human mouth).
[0025]
Next, main processing performed by the CPU 32 will be described with reference to the flowchart of FIG.
When the main process is started, first, in S110, it is determined whether or not sound is input from the microphone 18. Specifically, the determination is made based on whether or not the audio CODEC 26 has performed processing for converting the audio signal into audio data.
[0026]
If it is determined in S110 that the voice is input from the microphone 18, the process proceeds to S120, where the voice recognition device 28 analyzes the voice data generated by the voice CODEC 26, and the character string data represented by the voice data. Is generated.
Subsequently, in S130, it is determined whether or not the character string data generated in S120 represents a registered keyword. Here, the registration keyword is a signal issued by the user when registering the called name (corresponding to the identification name) which is the name of the headset 10, and the registration keyword in the present embodiment is “registration”. . In this embodiment, the name of the user of the headset 10 is registered in each headset 10 as the called name.
[0027]
If it is determined in S130 that the keyword represents a registered keyword, the process proceeds to S140, and after performing a called name registration process (FIG. 5) described later, the process returns to S110.
On the other hand, if it is determined in S130 that it does not represent a registered keyword, the process proceeds to S150, and whether the character string data generated in S120 represents a calling keyword (corresponding to a start keyword). Determine whether or not. Here, the call keyword is a signal issued by the user when voice communication with the user of the desired headset 10 is started, and the registered keyword in the present embodiment is “start”.
[0028]
If it is determined in S150 that it represents a calling keyword, the process proceeds to S160, performs a calling process (FIG. 6) described later, and then returns to S110.
On the other hand, if it is determined in S150 that it does not represent a calling keyword, the process proceeds to S170.
[0029]
On the other hand, if it is determined in S110 that no sound is input from the microphone 18, the process directly proceeds to S170.
In S170, it is determined whether or not character string data has been broadcast from another headset 10.
[0030]
If it is determined in S170 that the character string data has been broadcast, the process proceeds to S180 to perform a later-described called process (FIG. 8), and then returns to S110.
On the other hand, if it is determined in S170 that the character string data has not been broadcast, the process directly returns to S110.
[0031]
Next, called name registration processing performed by the CPU 32 will be described with reference to the flowchart of FIG. The called name registration process corresponds to the process of S140 in the main process (FIG. 4) described above.
When the called name registration process is started, first, in S210, the process waits until a voice is input from the microphone 18, and when a voice is input, the process proceeds to S220. Specifically, it is determined that sound is input by performing processing for converting the sound signal into sound data by the sound CODEC 26.
[0032]
Subsequently, in S220, the voice recognition device 28 is caused to analyze the voice data generated by the voice CODEC 26, and character string data represented by the voice data is generated.
Finally, in S230, the character string data generated in S220 is stored in the NVRAM 30 as called name data representing the called name of the headset 10, and the called name registration process is terminated. That is, the voice uttered after the registration keyword by the user of the headset 10 is registered as the called name of the headset 10.
[0033]
Next, the calling process performed by the CPU 32 will be described with reference to the flowchart of FIG. The calling process corresponds to the process of S160 in the main process (FIG. 4) described above.
When the calling process is started, first, in S310, the process waits until a voice is input from the microphone 18, and when a voice is input, the process proceeds to S320.
[0034]
Subsequently, in S320, the speech recognition device 28 is made to analyze the speech data generated by the speech CODEC 26 based on the speech input in S310, and character string data represented by the speech data is generated.
Subsequently, in S330, the character string data (corresponding to the identification name information) generated in S320 is broadcast to the Bluetooth module 24. Thereby, the character string data representing the content of the voice uttered after the call keyword by the user of the headset 10 is transmitted to all the headsets 10 existing in the communication area 2 of the headset 10. . The character string data to be broadcast here is the data to be determined in S170 in the main process (FIG. 4) described above.
[0035]
Subsequently, in S340, it is determined whether or not a connection request from another headset 10 is received by the Bluetooth module 24.
If it is determined in S340 that a connection request has not been received, the process proceeds to S350, and a predetermined timeout period (10 seconds in this embodiment) has elapsed since the character string data was broadcast in S330. It is determined whether or not.
[0036]
If it is determined in S350 that the timeout time has not elapsed, the process returns to S340.
On the other hand, if it is determined in S350 that the timeout time has elapsed, the calling process is terminated. That is, if a connection request from another headset 10 is not received by the time 10 seconds elapse after broadcasting the character string data, the calling process is terminated.
[0037]
On the other hand, if it is determined in S340 that a connection request from another headset 10 has been received, the process proceeds to S360, and in response to the connection request, the headset from which the connection request is transmitted (hereinafter referred to as a target). A calling side voice communication process (FIG. 7) to be described later for performing one-to-one voice communication with the call side headset 10 is performed. When the calling side voice communication process is completed, the process proceeds to S370, where a disconnection process for disconnecting the communication with the called headset 10 is performed, and the calling process ends.
[0038]
Next, the calling side voice communication process corresponding to the process of S360 will be described with reference to the flowchart of FIG.
When the calling side voice communication process is started, first, in S410, the process waits until any of the following data (1) to (3) is acquired, and any data is acquired. Then, the process proceeds to S420.
[0039]
(1): Voice data transmitted from the called-side headset 10
(2): Audio data generated by the audio CODEC 26 based on the audio input from the microphone 18
(3): Disconnection request transmitted from the called-side headset 10
In S420, it is determined whether or not the data acquired in S410 is voice data from the called headset 10 in (1) above.
[0040]
If it is determined in S420 that the voice data is from the called-side headset 10, the process proceeds to S430, where the voice CODEC 26 converts the voice data into a voice signal and outputs it from the speaker 22. Then, the process returns to S410. As a result, the voice represented by the voice data sent from the called-side headset 10 is output from the speaker 22.
[0041]
On the other hand, if it is determined in S420 that the data is not voice data from the called headset 10, the process proceeds to S440, and the data acquired in S410 is the voice generated by the voice CODEC 26 in (2) above. It is determined whether it is data.
If it is determined in S440 that the voice data is generated by the voice CODEC 26, the process proceeds to S450, and the Bluetooth module 24 transmits the voice data to the called-side headset 10, and then proceeds to S410. Return. As a result, voice data representing the voice uttered by the user of the headset 10 is transmitted to the called-side headset 10.
[0042]
On the other hand, if it is determined in S440 that the data acquired in S410 is not the voice data generated by the voice CODEC 26 (that is, the disconnection request from the called headset 10 in (3) above). Ends the calling side voice communication processing. As a result, the process of S370 in the above-described calling process (FIG. 6) is performed, and communication with the called-side headset 10 is disconnected.
[0043]
Next, called processing performed by the CPU 32 will be described with reference to the flowchart of FIG. The called process corresponds to the process of S180 in the main process (FIG. 4) described above.
When this called process is started, first, in S510, the character string represented by the character string data broadcast from the other headset 10 matches the called name represented by the called name data stored in the NVRAM 30. It is determined whether or not. Here, the broadcasted character string data is transmitted by performing the above-described calling process (FIG. 6) S330 in the transmission source headset (hereinafter referred to as the calling-side headset) 10. This data represents the content of the voice uttered after the calling keyword by the user of the calling-side headset 10. That is, in S510, it is determined whether or not the called name of the headset 10 has been issued after the calling keyword by the user of the calling headset 10. In the process of S510, it may be determined whether or not the character string and the called name are completely matched. However, if they are not completely matched but are similar to each other (for example, The presence or absence of long sound or cloudy sound may be regarded as matching.
[0044]
If it is determined in S510 that the character string represented by the broadcast character string data matches the called name, the process proceeds to S520, and a connection request to the calling-side headset 10 is transmitted to the Bluetooth module 24. Let
Subsequently, in S530, the voice CODEC 26 is caused to output a ringing tone from the speaker 22. Specifically, for example, digital data representing a beep sound “Peep-Pie ...” is output to the audio CODEC 26. Thereby, the user of the headset 10 can know that it has been called by the user of the calling-side headset 10.
[0045]
Subsequently, in S540, a called-side voice communication process (FIG. 9) described later for performing one-to-one voice communication with the calling-side headset 10 is performed. When this called-side voice communication process ends, the process proceeds to S550, a disconnection request is transmitted to the calling-side headset 10, and this called-call process ends.
[0046]
On the other hand, if it is determined in S510 that the character string represented by the broadcasted character string data does not match the called name, the called process is terminated.
Next, the called-side voice communication process corresponding to the process of S540 will be described with reference to the flowchart of FIG.
[0047]
When this called-side voice communication processing is started, first, in S610, voice data generated by the voice CODEC 26 based on voice data transmitted from the calling-side headset 10 and voice inputted from the microphone 18. Until one of the data is acquired, the process enters a standby state. When one of the data is acquired, the process proceeds to S620.
[0048]
In S620, it is determined whether or not the data acquired in S610 is voice data from the calling-side headset 10.
If it is determined in S620 that the audio data is from the calling-side headset 10, the process proceeds to S630, where the audio CODEC 26 converts the audio data into an audio signal and outputs it from the speaker 22. Then, the process returns to S610. As a result, the voice represented by the voice data sent from the calling-side headset 10 is output from the speaker 22.
[0049]
On the other hand, if it is determined in S620 that the data is not voice data from the calling-side headset 10 (that is, voice data generated by the voice CODEC 26), the process proceeds to S640, and the voice data is converted into a voice recognition device. 28, the character string data represented by the voice data is generated.
[0050]
Subsequently, in S650, it is determined whether or not the character string data generated in S640 represents a disconnect keyword (corresponding to the called-side termination keyword). Here, the disconnect keyword is a signal issued by the user when the voice communication with the calling-side headset 10 is terminated, and the disconnect keyword in the present embodiment is “disconnect”.
[0051]
If it is determined in S650 that the keyword does not represent a disconnection keyword, the process proceeds to S660, and the Bluetooth module 24 transmits the voice data generated by the voice CODEC 26 to the calling headset 10. Return to S610. As a result, voice data representing voice other than the disconnected keyword issued by the user of the headset 10 is transmitted to the calling-side headset 10.
[0052]
On the other hand, if it is determined in S650 that the keyword represents a disconnection keyword, the called-side voice communication processing is terminated. Thereby, the process of S550 in the aforementioned called process (FIG. 8) is performed, and a disconnection request is transmitted to the calling-side headset 10.
Next, the operation of the communication system will be described.
[0053]
[Registering the called name to the headset]
When the user of the headset 10 registers his / her name as the called name of the headset 10, he / she first issues “registration” and subsequently “xxx (your name)”. Thereby, in the headset 10, the following processing is performed.
That is, first, when the user utters “registration”, it is determined by the main process of FIG. 4 that the voice is inputted from the microphone 18 (S110: YES), and the voice utters the registration keyword. (S120, S130: YES), the process proceeds to the called name registration process of FIG. 5 (S140). Subsequently, when the user utters “XX”, the “XXX” is stored as a called name (S210 to S230). That is, it is determined that the word that the user has spoken immediately after the registered keyword is the word to be registered as the called name, and that word is registered as the called name.
[0054]
[Voice communication between headsets]
When a user of one headset 10 (hereinafter referred to as headset A) starts voice communication with a user of another headset 10 (hereinafter referred to as headset B), as shown in FIG. First, “Start” is issued, followed by “XX (name of the user of the headset B)”. As a result, the following processing is performed in the headset A on the calling side and the headset B on the called side.
[0055]
That is, first, when the user of the headset A issues “Start”, the headset A determines that the voice is input from the microphone 18 by the main processing of FIG. 4 (S110: YES), and further, the voice. Is determined to have originated the calling keyword (S120, S150: YES), the process proceeds to the calling process of FIG. 6 (S160). Subsequently, when the user issues “XX”, the character string data representing the “XXX” is broadcast to another headset that can communicate with the headset A (S310 to S330). That is, it is determined that the word that the user has spoken immediately after the calling keyword is the called name of the headset (headset B in this example) that the user of headset A wants to call, and represents the called name. String data is broadcast.
[0056]
Then, the headset B determines that the character string data has been broadcast from the headset A by the main process of FIG. 4 (S170: YES), and proceeds to the called process of FIG. 8 (S180). Then, it is determined that the character string “XXX” represented by the character string data that has been broadcast matches the called name of the headset B (S510: YES), and a connection request is transmitted to the headset A (S520). ). Further, after the ringing tone is output (S530), the process proceeds to the called-side voice communication process of FIG. 9 (S540). In other headsets other than the headset B, it is determined in step S510 that the character string “XXX” represented by the character string data that has been broadcast does not match the called name of the headset. Then, the called process is terminated as it is.
[0057]
Then, in headset A, it is determined that the connection request from headset B has been received by the calling process in FIG. 6 (S340: YES), and the process proceeds to the calling side voice communication process in FIG. 7 (S360). .
Thus, in a state where the calling side voice communication processing is performed in the headset A and the called side voice communication processing is performed in the headset B, as shown in FIG. 10, the user of the headset A and the headset Voice communication is possible with the user of B.
[0058]
For example, when the user of the headset A is emitted as "Hello", the caller voice communication process in FIG. 7, the audio data representing the speech is transmitted to the headset B (S410, S440: YES, S450) . Then, the headset B, the called party voice communication processing of FIG. 9, the voice "Hello" represented by the audio data transmitted from the headset A is output from the speaker 22 (S610, S620: YES, S630 ).
[0059]
Then, contrast, headset users of B is "very much, Hello" when utters, by the called party voice communication processing of FIG. 9, the audio data representing the speech is transmitted to the headset A (S610, S650: NO, S660). Then, the headset A, the calling voice communication process in FIG. 7, the speech "very much, Hello" represented by the audio data transmitted from the headset B is output from the speaker 22 (S410, S420: YES , S430).
[0060]
Thereafter, when the voice communication is terminated, the user of the headset B issues “disconnect” as shown in FIG. Thereby, in the headset A and the headset B, the following processing is performed.
That is, when the user of the headset B utters “disconnect”, the headset B determines that the speech originates the disconnect keyword by the called-side voice communication processing of FIG. 9 (S610, S650). : YES), the called-side voice communication processing is terminated. Then, a disconnection request is transmitted to the headset A by the called process of FIG. 8 (S550).
[0061]
Then, in headset A, it is determined that a disconnection request has been transmitted from headset B by the calling side voice communication processing of FIG. 7 (S410, S440: NO), and the calling side voice communication processing is terminated. . Then, a disconnection process for disconnecting communication with the headset B is performed by the calling process of FIG. 6 (S370).
[0062]
In the communication system of the present embodiment, the headset 10 corresponds to the calling side terminal and the called side terminal, and in particular, in the example shown in FIG. 10, the headset A corresponds to the calling side terminal. The headset B corresponds to the called terminal.
The microphone 18 corresponds to a calling side input unit, a called side input unit, and an input unit. The processing of S120, S150, and S160 in FIG. 4 and the processing of S310 in FIG. Correspondingly, the Bluetooth module 24 and the process of S330 in FIG. 6 correspond to a transmission means.
[0063]
Further, the NVRAM 30 corresponds to the storage means, the processing in S510 in FIG. 8 corresponds to the called determination means, the Bluetooth module 24 and the processing in S520 in FIG. 8 correspond to the communication start means, and Bluetooth. The module 24, the processing of S640 and S650 in FIG. 9, and the processing of S550 in FIG. 8 correspond to the called-side communication end means.
[0064]
On the other hand, the processing of S120 to S140 in FIG. 4 and the processing of S210 in FIG. 5 correspond to registration determination means, and the processing of S220 and S230 in FIG. 5 corresponds to identification name registration means. The process of S530 in FIG. 8 corresponds to the notification means.
[0065]
According to such a communication system of this embodiment, it is only necessary to register the called name of each headset 10 in each headset 10, and there is no need to register information about other headsets 10. Therefore, information to be stored can be reduced.
[0066]
That is, in the conventional communication system, the called name and the communication destination address of the communication device that is a candidate for the communication destination must be registered in each of the communication devices that can be the calling party. If it is applied to such a communication system, it is necessary to register the called names and communication destination addresses of all the other headsets 10 in each headset 10.
[0067]
On the other hand, in the communication system of the present embodiment, only the called name of the headset 10 needs to be registered in each headset 10, and therefore the amount of information to be registered in each headset 10 may be significantly reduced. it can. The amount of information to be registered in each headset 10 by the communication system in this way can be reduced because the information about the same headset 10 is a plurality of headsets 10 when viewed from the entire communication system. This is because there is no waste of being registered in duplicate, and the total amount of information to be registered in the headset 10 can be reduced.
[0068]
Furthermore, in the communication system according to the present embodiment, the headset 10 determines a request from the user, such as the start or end of voice communication, based on a keyword issued from the user. Free voice communication can be realized. Moreover, the user can easily perform registration of the called name in a hands-free manner.
[0069]
In addition, in the communication system according to the present embodiment, the headset 10 is configured to notify with a ringing tone when receiving a call from another headset 10, so that the voice can be heard while the user is not aware. It is possible to prevent communication from being started.
[0070]
As mentioned above, although one Embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form.
For example, in the communication system of the above embodiment, the voice communication is terminated when the user of the headset 10 on the called side issues a disconnect keyword, but the present invention is not limited to this. For example, the voice communication may be similarly terminated when the user of the calling headset 10 issues a disconnect keyword. Specifically, the following processing is performed before the processing of S450 of the calling side voice communication processing (FIG. 7).
[0071]
That is, after determining that the voice data is generated by the voice CODEC 26 in S440, the voice recognition device 28 generates the character string data represented by the voice data, and the character string data is a keyword used when the voice communication is terminated. It is determined whether it represents (corresponding to the caller end keyword). If it is determined that it does not represent the keyword, the process proceeds to S450, but if it is determined that it represents the keyword, a disconnection request is transmitted to the called-side headset 10 and issued. The call side voice communication process is terminated. Note that the processing described here and the Bluetooth module 24 correspond to calling side communication end means.
[0072]
Further, in the communication system of the above embodiment, the calling-side headset 10 generates character string data from voice data based on the voice uttered after the call keyword by the user, and broadcasts the character string data. However, it is not limited to this. For example, the calling-side headset 10 broadcasts voice data based on the voice uttered next to the calling keyword as it is, and the called-side headset 10 receives character string data from the broadcast voice data. May be generated.
[0073]
Furthermore, in the communication system of the above-described embodiment, the headset 10 determines a request from the user such as the start or end of voice communication based on a keyword issued from the user. Not a thing. For example, a configuration in which an operation button is pressed instead of a keyword being issued (a configuration in which a word issued immediately after the operation button is pressed is determined as the called name of the headset 10 that the user wants to call. ).
[0074]
Each keyword is not limited to those exemplified in the above embodiment (“registration”, “start”, “disconnect”). For example, if a word that is not used in normal conversation is used, it is possible to prevent a user's casual word from being mistakenly recognized as a keyword against the user's intention. Moreover, even if it is a word used normally, misrecognition can be prevented by adding conditions, such as putting fixed silence time before and after that.
[0075]
On the other hand, in the communication system of the above embodiment, the headset 10 is used as a communication device, but other communication devices may be used. Also, the communication method is not limited to Bluetooth, and other various communication methods (for example, wired communication using TCP / IP) can be used.
[0076]
In the communication system of the above embodiment, each headset 10 as a communication device functions as both a calling terminal and a called terminal, but is not limited thereto. A dedicated communication device having only one of the functions may be used. Also in this case, since only the called name of the communication device needs to be registered in the communication device functioning as the called terminal, the amount of information to be registered in the communication device can be reduced.
[0077]
Furthermore, in the communication system of the above embodiment, one-to-one voice communication with the headset is performed by issuing the called name of the headset 10 that is desired to be a communication partner. For example, voice communication with a plurality of opponents may be performed by issuing names of a plurality of opponents. In addition, during voice communication with a plurality of opponents, the name of a specific opponent may be issued to switch to one-to-one voice communication with that partner.
[0078]
On the other hand, the communication performed between the communication devices may be other than voice conversation. For example, the contents of the voice input from the calling communication device may be displayed as characters on a display provided in the called communication device, or the called communication device. The text input with the keyboard provided in the may be displayed on the communication device on the calling side.
