Below, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

First Embodiment
(Audio conference system)
First, a remote conference system, which is an example of an information processing system, will be described.
Fig. 1 is a schematic diagram showing an example of the configuration of a remote conference system according to an embodiment of the present invention. As shown in Fig. 1, the remote conference system 10 includes a server device 12 for remote conferences and terminal devices 14 used by participants who participate in the remote conference. The terminal devices 14 and the server device 12 are connected to each other so as to be able to communicate with each other via a wired or wireless communication line 16 such as the Internet or a LAN.

In FIG. 1, four terminal devices 14A, 14B, 14C, and 14D are illustrated, but there is no particular limit to the number of terminal devices 14, and it is sufficient that there are two or more. When there is no need to distinguish between the terminal devices 14A, 14B, 14C, and 14D, they will be collectively referred to as terminal devices 14.

An application program for remote conferences (hereinafter referred to as the "remote conference program") is installed on the terminal device 14. Participants start the remote conference program and connect the terminal device 14 to the remote conference server device 12 to participate in the remote conference. An audio input device such as a microphone for inputting audio, and an audio output device such as a speaker or earphones for outputting audio are connected to the terminal device 14.

The terminal device 14 transmits audio information corresponding to the audio input from the audio input device to the server device 12. The server device 12 distributes the audio information acquired from each terminal device 14 to each terminal device 14. The audio output device connected to each terminal device 14 reproduces and outputs audio corresponding to the received audio information.

This allows remote conference participants to speak and hear what they and the other participants are saying. Compared to text-based chat, audio remote conferences are more convenient in that it is easier to send and receive information, and a large number of people can instantly share and discuss information.

In the illustrated example, the terminal device 14A is placed in a conference room at the head office. The terminal device 14A is a terminal used by Mr. A, the organizer of the remote conference. A microphone, a speaker, a display which is an example of a display unit, a projector, etc. are connected to the terminal device 14A. There are other participants in the conference room at the head office besides Mr. A, the organizer. The projector projects conference materials, etc.

The terminal device 14B is a terminal used by participant B of the remote conference. Participant B works from home, and the terminal device 14B is located in participant B's home. A microphone, earphones, a display, etc. are connected to the terminal device 14B.

The terminal device 14C is a mobile terminal used by participant C of the remote conference. Participant C works outside the company, such as in a rented office, and the terminal device 14C is used outside the company. The terminal device 14C is equipped with a microphone, earphones, a small display, etc.

The terminal device 14D is placed in the branch office's conference room. A microphone, speaker, display, projector, etc. are connected to the terminal device 14D. At least one participant is present in the branch office's conference room. Entry to the head office's conference room and the branch office's conference room is prohibited to anyone other than related parties.

(Terminal device)
Next, the terminal device will be described.
Fig. 2 is a block diagram showing an example of the electrical configuration of the terminal device 14. As shown in Fig. 2, the terminal device 14 includes an information processing unit 20. The information processing unit 20 is configured as a computer that controls the entire device and performs various calculations.

Specifically, the information processing unit 20 includes a CPU 20A, a ROM 20B that stores various programs, a RAM 20C that is used as a work area when the programs are executed, a non-volatile memory 20D that stores various data, and an input/output interface (I/O) 20E. Each of the CPU 20A, ROM 20B, RAM 20C, memory 20D, and I/O 20E is connected via a bus 20F.

The various programs and data may be stored in other storage devices or on recording media such as a CD-ROM. The various programs and data may be acquired via communications.

An operation unit 22, a display unit 24, a memory unit 26, a communication unit 28, and an audio input/output interface (I/F) 30 are connected to the I/O 20E. The operation unit 22 accepts operations from a user. The display unit 24 displays various information to the user. The memory unit 26 is an external storage device such as a hard disk. The communication unit 28 is an interface for communicating with external devices. The audio input/output I/F 30 is an interface for inputting and outputting audio. The information processing unit 20 controls each unit by sending and receiving information between each unit.

The voice input/output I/F 30 includes a microphone 32, which is an example of a voice input device for inputting voice.
A speaker (or earphone) 34, which is an example of an audio output device that outputs audio, is connected. The audio input/output I/F 30 converts an acoustic signal detected by the microphone 32 into a digital signal, and inputs it to the information processing unit 20 as audio information. The audio input/output I/F 30 also converts audio information acquired from the information processing unit 20 into an acoustic signal for outputting audio from the speaker or the like 34, and outputs it to the speaker or the like 34.

(Server device)
Next, the hardware configuration of the server device will be described.
Fig. 3 is a block diagram showing an example of the electrical configuration of the server device. As shown in Fig. 3, the server device 12 includes an information processing unit 40. The information processing unit 40 is configured as a computer that controls the entire device and performs various calculations. Both the terminal device 14 and the server device 12 function as information processing devices, and the server device 12 is an example of an "information processing device".

The information processing unit 40 includes a CPU 40A, a ROM 40B that stores various programs, a RAM 40C that is used as a work area when the programs are executed, a non-volatile memory 40D that stores various data, and an input/output interface (I/O) 40E. Each of the CPU 40A, ROM 40B, RAM 40C, memory 40D, and I/O 40E is connected via a bus 40F.

The various programs and data may be stored in another storage device or on a recording medium such as a CD-ROM. The various programs and data may also be acquired via communication.

The I/O 40E is connected to a storage unit 42, which is an external storage device, and a communication unit 44, which is an interface for communicating with external devices. The information processing unit 40 controls each unit by sending and receiving information between each unit.

Next, the functional configuration of the server device will be described.
4 is a functional block diagram showing an example of the functional configuration of the server device according to the first embodiment. As shown in FIG. 4, the server device 12 includes a voice information acquisition unit 50, a voice information output unit 52, a volume detection unit 56, a volume determination unit 58, a threshold storage unit 60, and a warning output unit 62.

The audio information acquisition unit 50 acquires audio information from each terminal device 14. The audio information output unit 52 distributes the audio information acquired from the audio information acquisition unit 50 to each terminal device 14 in time synchronization. The volume detection unit 56 detects speech from the audio information acquired from the terminal device 14 for each terminal device 14, and detects the volume of the detected speech. Here, "volume" refers to the amount (level) of sound pressure expressed as the common logarithm of the ratio with respect to a reference value. The unit is decibels [dB]. The volume detection unit 56 outputs the detection result to the volume determination unit 58.

The volume determination unit 58 acquires the threshold value stored in the threshold memory unit 60, and compares the volume detected by the volume detection unit 56 with the threshold value to determine whether the detected volume exceeds the threshold value. When the volume determination unit 58 determines that the volume exceeds the threshold value, it outputs the determination result to the warning output unit 62. The warning output unit 62 outputs a warning to the terminal device 14 (hereinafter referred to as the "problematic terminal") whose volume has been determined by the volume determination unit 58 to exceed the threshold value.

(Specific example)
Here, a specific example will be described (see FIG. 1).
5 is a schematic diagram showing a specific example of the first embodiment. Assume a case where participant B, who works at home, speaks in a remote conference. When participant B speaks into a microphone, voice information is transmitted from terminal device 14B to server device 12. Server device 12 distributes participant B's voice (information) to other terminal devices 14A, 14C, and 14D in real time. Server device 12 also detects participant B's speech and measures the volume of the detected speech.

Here, the volume threshold stored in server device 12 is assumed to be 60 dB (the volume of a typical conversation). When the volume of participant B's speech exceeds 60 dB, server device 12 transmits a warning notification to terminal device 14B. Upon receiving the warning notification, terminal device 14B displays a warning message on the display unit stating, "Your voice is too loud! Please lower your voice." Participant B is prompted to lower the volume of his or her speech.

In this embodiment, Participant B and Participant C participate in the remote conference from outside the company, such as from their homes or rental offices. External locations pose a higher security risk than corporate locations, as it is easier for third parties to intervene. In addition, devices that are always connected to a network and collect audio, such as smart speakers, have become widespread in recent years. Therefore, the speech of participants participating in the remote conference is monitored, and a warning is issued to speakers who engage in problematic behavior, such as speaking too loudly, thereby reducing the risk of confidential information leaks caused by speaking.

The warning method is not limited to displaying a warning message, as long as it can prompt the speaker to take action to avoid the warning. A warning voice or sound may be output from the audio output device of the terminal device 14. For example, in the example shown in FIG. 1, participant C uses a mobile terminal, and it may be difficult for him or her to participate in the remote conference while looking at the screen. In such a case, it is effective to play a warning voice or sound directly on the earphones instead of displaying it on the screen.

In addition, the volume of speech of participants who speak loudly may be lowered or the distribution of speech may be stopped (microphone off). The server device 12 may lower the volume when distributing the voice information acquired from the question terminal, or stop distributing the voice information acquired from the question terminal, etc. Alternatively, the server device 12 may instruct the question terminal to lower the voice input volume at the question terminal, stop voice input at the question terminal, etc.

For example, in the example shown in FIG. 4, the volume determination unit 58 outputs terminal information such as the terminal ID of the problematic terminal to the audio information output unit 52. The audio information output unit 52 stops the distribution of the audio information acquired from the problematic terminal.

(Remote conference program)
Next, the remote conference program will be described.
6 is a flowchart showing an example of a process flow of the "remote conference program" according to the first embodiment. The remote conference program is started when the host issues an instruction to execute the program from a terminal device and the instruction to execute the program is accepted by the CPU of the server device.

First, in step 100, audio information is acquired from each terminal device. Next, in step 102, the audio information is distributed to each terminal device. Next, in step 104, "volume response processing" is executed. Next, in step 106, it is determined whether or not the conference has ended. An instruction to end the conference is given from the host's terminal device, and the process ends when the instruction to end is accepted by the CPU of the server device. If the conference has ended, the routine ends, and if the conference has not ended, the process returns to step 100 and the procedures from step 100 to step 106 are repeated.

Next, the "volume response process" will be described.
7 is a flow chart showing an example of the flow of the "volume handling process." In the "volume handling process," if the volume of a participant's speech is louder than a threshold, a warning is issued to the speaker.

First, in step 200, one terminal device is selected. Next, in step 202, a volume threshold corresponding to the terminal device is acquired. The memory unit of the server device stores a speech volume threshold for each terminal device. Next, in step 204, the speech volume is detected from the audio information acquired from the selected terminal device.

Next, in step 206, it is determined whether the volume of the detected speech exceeds a threshold. If the threshold is exceeded, the process proceeds to step 208, where a warning is output. The warning information is sent to the selected terminal device, and a warning is issued to the participant with the loud speech. If the threshold is not exceeded, step 208 is skipped and the process proceeds to step 210.

Next, in step 210, it is determined whether there are any other terminal devices that have not been selected. If there are any other terminal devices that have not been selected, the process returns to step 200 to select the next terminal device, and the procedure from step 200 to step 210 is repeated. If there are no other terminal devices that have not been selected, the routine ends.

Second Embodiment
In the second embodiment, the speech volume threshold is set according to the location of the terminal device, but other than that, the second embodiment is similar to the first embodiment, and therefore a description of the same parts will be omitted.

Figure 8 is a diagram showing the relationship between terminal IDs and locations. Here, the symbol for terminal device 14 shown in Figure 1 is taken as the terminal ID for identifying the terminal device. As described above, terminal device 14A is located in a conference room at the head office. Terminal device 14B is located in participant B's home. Terminal device 14C is used outside the company (other than at home). Terminal device 14D is located in a conference room at the branch office.

In-house facilities, such as conference rooms at the head office or branch office, generally have access management, so there is no problem with conversations being held at a louder volume than outside the company. Also, when multiple people gather in one conference room, the volume of the conversation must be made louder in order for the other participants to hear it. For this reason, a louder volume threshold may be set for terminal device 14A and terminal device 14D located within the company than for the others, or the volume may be unlimited.

Figure 9 is a diagram showing the relationship between the location and the threshold. For example, if the location is the head office, a branch office, or home, the threshold is A, and if the location is outside the company other than home, the threshold is B (< A). The volume of a typical conversation is 60 dB. For example, threshold A may be 70 dB and threshold B may be 40 dB.

Third Embodiment
Whether or not a third party can easily hear a voice also depends on the surrounding environmental noise. For example, in the example shown in Figure 1, if participant B's house is close to a road with a lot of traffic, it is difficult for others to hear participant B even if he speaks louder. On the other hand, if participant B's house is in a quiet residential area, he may be heard by others even at a lower volume.

Therefore, in the third embodiment, the speech volume threshold is set according to the environmental sound at the location where the terminal device is placed. The terminal device obtains a threshold according to the environmental sound volume, and notifies the server device of the obtained threshold. The threshold is set according to the environmental sound volume so that the speech cannot be heard by a third party. Other than that, the third embodiment is the same as the first embodiment, so a description of the same parts will be omitted.

Figure 10 is a sequence diagram showing the procedure for notifying the threshold value. As shown in Figure 10, in step 300, the terminal device 14 acquires audio information of the environmental sound picked up by an audio input device such as a microphone. Next, in step 302, the volume of the environmental sound is detected from the acquired audio information. For example, the volume of the surrounding environmental sound is constantly measured, and the average volume of the environmental sound is acquired. Next, in step 304, a threshold value according to the volume of the environmental sound is calculated. For example, the threshold value is set to a value obtained by adding 20 dB to the average volume of the environmental sound. Next, in step 306, the calculated threshold value is notified to the server device 12.

Next, the functional configuration of the server device will be described.
11 is a functional block diagram showing an example of a functional configuration of a server device according to the third embodiment. As shown in FIG. 11, the server device 12 includes a voice information acquisition unit 50, a voice information output unit 51, and a voice information acquisition unit 52.
2, a volume detection unit 56, a volume determination unit 58, a threshold setting unit 70, and a warning output unit 62. Except for the provision of the threshold setting unit 70 instead of the threshold storage unit 60, the functional configuration is the same as that of the server device shown in Fig. 4, and therefore the same components are denoted by the same reference numerals and description thereof will be omitted.

The threshold setting unit 70 sets the threshold notified from each terminal device 14 as the "threshold" of that terminal device. The set threshold is stored in association with the terminal ID of that terminal device. The volume determination unit 58 acquires the threshold stored in the threshold setting unit 70, and compares the volume detected by the volume detection unit 56 with the threshold to determine whether the detected volume exceeds the threshold.

<Fourth embodiment>
In the first embodiment, an example was described in which a warning was issued to a participant who was speaking loudly, but in the fourth embodiment, a warning is issued to other participants. For example, when a warning is output in step 208 in Fig. 7, warning information is sent to the terminal device used by the organizer. Other than that, the fourth embodiment is the same as the first embodiment, and therefore a description of the same parts will be omitted.

Figure 12 is a schematic diagram showing a specific example of the fourth embodiment. In the example shown in Figure 12, the server device 12 (see Figure 1) sends a warning notification to the terminal device 14A of the organizer A when the volume of the speech of participant B exceeds 60 dB. When the terminal device 14A receives the warning notification, it displays a warning message on the display unit connected to the terminal device 14A saying, "Person B's voice is too loud!".

Organizer A can take various measures, such as warning participant B, "Mr. B, aren't you speaking too loudly?", prohibiting Mr. B from speaking, or temporarily pausing the discussion to forcefully calm things down. Alternatively, as described below, organizer A may operate terminal device 14A to stop the distribution of participant B's voice. There is a possibility that Mr. B, the speaker, will be engrossed in the discussion and overlook the warning, so it may be more effective to issue a warning to other participants.

Fifth embodiment
In a meeting that deals with multiple topics, there are topics with high confidentiality and topics with low confidentiality. In such a case, if a threshold is set based on the criteria for the topics with high confidentiality, there is a risk that sufficient discussion will not be held on the topics with low confidentiality.

Therefore, in the fifth embodiment, the organizer sets the speech volume threshold according to the agenda. The organizer's terminal device determines the threshold according to the security level of the agenda, and notifies the server device of the obtained threshold. The organizer changes the security level according to the progress of the remote conference. The speech volume threshold changes according to changes in the security level. Other than that, the fifth embodiment is the same as the first embodiment, so a description of the same parts will be omitted.

Figure 13 is a schematic diagram showing an example of a setting screen according to the fifth embodiment. For example, a setting screen 100 is displayed on the display unit of the terminal device 14A of the organizer A to accept the setting of the security level. The setting screen 100 includes an icon 102 of the organizer, icons 106 of the participants, a setting section 104 for setting the security level, a setting section 108 for setting the volume, a button 110 for issuing a confirmation command, a button 112 for issuing a cancellation command, etc.

Figure 14 is a chart showing the relationship between security levels and thresholds. As shown in Figure 14, multiple security levels are available. In the example shown, there are five levels, from "1" to "5," with the security level increasing in ascending order. Thresholds E to A are set for security levels 1 to 5. The higher the security level, the smaller the threshold.

Figure 15 is a sequence diagram showing the procedure for threshold notification. As shown in Figure 15, in step 400, terminal device 14A acquires the set security level. Next, in step 402, it acquires a threshold corresponding to the acquired security level. Next, in step 404, it notifies the acquired threshold.

For example, the organizer operates the setting section 104, buttons 110, etc. of the setting screen 100 shown in FIG. 13 to set a security level according to the agenda. For example, for an agenda with high confidentiality, the security level is set to "5." A threshold A (e.g., 20 dB) corresponding to level 5 is obtained and notified to the server device 12. For an agenda with high confidentiality, the volume threshold is set low and the volume of speech is limited, improving confidentiality.

On the other hand, for topics that are not very confidential, the security level is set to "3." A threshold C (e.g., 50 dB) corresponding to level 3 is obtained and notified to the server device 12. For topics that are not very confidential, the volume threshold is set high, allowing the remote conference to proceed without worrying about the volume of speech, improving convenience.

Sixth embodiment
In the fifth embodiment, an example was described in which the organizer sets the threshold for the volume of speech depending on the agenda. In the sixth embodiment, the organizer sets the volume at which the voice acquired from each terminal device is distributed. For example, the organizer operates the setting section 108, button 110, etc. of the setting screen 100 shown in Fig. 13 to set the volume at which the voice acquired from each terminal device is distributed. Other than that, the present embodiment is similar to the first embodiment, and therefore a description of the same parts will be omitted.

Figure 16 is a sequence diagram showing the procedure for notifying the set volume. As shown in Figure 16, in step 500, the terminal device 14A acquires the volume set for each terminal device. Next, in step 502, the acquired set volume is notified to the server device 12.

Next, the functional configuration of the server device will be described.
Fig. 17 is a functional block diagram showing an example of the functional configuration of a server device according to the sixth embodiment. As shown in Fig. 17, the server device 12 includes a voice information acquisition unit 50, a voice information output unit 52, a volume detection unit 56, a volume determination unit 58, a threshold storage unit 60, a warning output unit 62, and a volume adjustment unit 54. Since the server device 12 has the same functional configuration as the server device shown in Fig. 4 except for the volume adjustment unit 54, the same components are denoted by the same reference numerals and description thereof will be omitted.

The audio information acquisition unit 50 acquires audio information from each terminal device 14. The volume adjustment unit 54 acquires the set volume of each terminal device 14 from the organizer's terminal device 14A. The volume adjustment unit 54 adjusts the volume of the audio information of each terminal device 14 acquired from the audio information acquisition unit 50 according to the set volume of each terminal device 14. The audio information output unit 52 distributes the audio information after the volume adjustment to each terminal device 14.

For example, as shown in FIG. 12, when the organizer A sees the warning message "B's voice is too loud!", he or she operates the setting section 108, the button 110, etc. of the setting screen 100 shown in FIG. 13 to set the volume of the voice acquired from the terminal device 14B (B's home) to 0 dB.
, that is, the microphone is off.

Seventh embodiment
In the first to sixth embodiments, a warning is issued when the volume of the speech exceeds a threshold, but in the seventh embodiment, a warning is issued when the content of the speech includes a confidential term. Other than that, the seventh embodiment is the same as the first embodiment, so a description of the same parts will be omitted.

(Server device)
Next, the functional configuration of the server device will be described.
Fig. 18 is a functional block diagram showing an example of the functional configuration of a server device according to the seventh embodiment. As shown in Fig. 18, the server device 12 includes a voice information acquisition unit 50, a voice information output unit 52, a voice recognition unit 80, a confidential information detection unit 82, a volume adjustment unit 54, and a warning output unit 84.

The voice information acquisition unit 50 acquires voice information from each terminal device 14. The voice recognition unit 80 performs voice recognition processing on the voice information acquired from the voice information acquisition unit 50 and converts the content of the utterance into text data. The voice recognition processing is performed for each terminal device. The confidential information detection unit 82 extracts predetermined confidential terms from the text data obtained by the voice recognition unit 80. Here, "confidential terms" are terms included in information that is treated as confidential, such as trade secrets and personal information. For example, proper nouns such as project names, product names, company names, and names of laws and regulations may be considered confidential terms.

When a confidential term is detected, the confidential information detection unit 82 identifies the terminal device 14 that inputted the audio information containing the confidential term (hereinafter referred to as the "problem terminal") and notifies the volume adjustment unit 54 and the warning output unit 84 of terminal information such as the terminal ID of the problem terminal. The volume adjustment unit 54 adjusts the volume of the audio information of the problem terminal among the audio information acquired from the audio information acquisition unit 50. For example, the volume at which the audio information acquired from the problem terminal is distributed is lowered or set to zero. The audio information output unit 52 distributes the audio information after the volume adjustment to each terminal device 14.

The warning output unit 84 outputs a warning to the problematic terminal. By monitoring the speech of participants in a remote conference and issuing a warning to speakers who engage in problematic behavior, such as speaking outside the company using confidential terminology, the system reduces the risk of confidential information leaks caused by speech.

Here, a specific example will be given for explanation.
FIG. 19 is a schematic diagram showing a specific example of the seventh embodiment.
Assume that participant B, who works at home, speaks during a remote conference. When participant B speaks into the microphone, the voice (information) of participant B is distributed in real time to other terminal devices 14A, 14C, and 14D. In addition, server device 12 detects participant B's speech and converts the content of the speech into text data by speech recognition processing.

When the server device 12 detects that confidential terms were included in the content of participant B's speech, it sends a warning notification to the terminal device 14B. When the terminal device 14B receives the warning notification, it displays a warning message on the display unit stating, "Confidential terms have been used. Please be careful when you speak." A warning voice or sound may also be output. Participant B is urged to be careful about what he or she says.

In addition, when the server device 12 detects that confidential terms are included in the content of the speech of participant B, it lowers the volume of the audio information acquired from the terminal device 14B. It may also stop the distribution.

Alternatively, even if the server device 12 detects that the contents of the speech of participant B contain confidential terminology, it may issue a warning notification or reduce the volume only if the volume of the audio information acquired from the terminal device 14B exceeds a threshold value. This allows participants to speak in a low voice when talking about confidential terminology and in a high voice when talking about general conversations, thereby reducing the leakage of confidential information due to speaking while maintaining the convenience of audio conferences.

(Remote conference program)
Next, the remote conference program will be described.
20 is a flowchart showing an example of the process flow of the "remote conference program" according to the seventh embodiment. The remote conference program is started when the host issues an instruction to execute the program from a terminal device and the instruction to execute the program is accepted by the CPU of the server device.

First, in step 600, audio information is acquired from each terminal device. Next, in step 602, "confidentiality handling processing" is executed. Next, in step 604, the audio information is distributed to each terminal device. Next, in step 606, it is determined whether or not the conference has ended. An instruction to end the conference is given from the host's terminal device, and the conference ends when the instruction to end is accepted by the CPU of the server device. If the conference has ended, the routine ends, and if the conference has not ended, the process returns to step 600 and the procedures from step 600 to step 606 are repeated.

Next, the "confidentiality management process" will be described.
21 is a flow chart showing an example of the flow of the "confidentiality handling process." In the "confidentiality handling process," if the content of a participant's speech contains confidential words, a warning is given to the speaker and the volume of the speech is reduced.

First, in step 700, one terminal device is selected. Next, in step 702, speech recognition processing is performed on the voice information obtained from the terminal device, and the contents of the utterance are converted into text data. Next, in step 704, predetermined confidential terms are extracted from the text data obtained by the speech recognition processing. Next, in step 706, it is determined whether the contents of the utterance include confidential terms. If confidential terms are included, the process proceeds to step 708, and if confidential terms are not included, the process proceeds to step 712.

Next, in step 708, the volume of the audio information acquired from the terminal device is reduced. Next, in step 710, a warning is output. The warning information is sent to the selected terminal device, and a warning is given to the speaker of the utterance that includes the confidential term.

Next, in step 712, it is determined whether there are any other terminal devices that have not been selected. If there are any other terminal devices that have not been selected, the process returns to step 700 to select the next terminal device, and the procedures from step 700 to step 710 are repeated. If there are no other terminal devices that have not been selected, the routine ends.

<Modification>
It should be noted that the configurations of the information processing device, the program, and the information processing system described in the above embodiment are merely examples, and it goes without saying that the configurations may be changed without departing from the spirit of the present invention.

In the first to sixth embodiments, an example is described in which a warning is issued when the volume of speech exceeds a threshold, and in the seventh embodiment, an example is described in which a warning is issued when the content of speech includes confidential terms. However, a warning may be issued at least when the volume of speech exceeds a threshold and when the content of speech includes confidential terms.

In addition, in the above embodiment, the remote conference system is configured to include a server device, but any of the terminal devices used in the remote conference, such as the organizer's terminal device, may also include the functionality of a server device.

In addition, in the above embodiment, an example was described in which each function was realized by software, but each function may also be realized by hardware.
