A user of the conversation support system 1 participates in the online conference by operating the information processing device 30, for example.

(Mask 10)
The mask 10 is, for example, a sanitary mask for home or medical use, and is worn by a user for the purpose of preventing infectious diseases. This mask 10 is, for example, configured to be disposable, and is discarded after being used once or several times. Mask 10 may be used repeatedly. The mask 10 is made of, for example, cloth such as nonwoven fabric, paper, resin, or the like. The mask 10 includes, for example, a mouth covering portion 11 and a pair of string portions 12 connected to both ends of the mouth covering portion 11 .

The mouth covering part 11 is a part that covers the user's mouth and nose when the user wears the mask 10 . By covering the user's mouth and nose with the mouth covering part 11, the effect of the mask 10, such as prevention of infectious diseases, is exhibited. The shape of the mouth covering part 11 is, for example, substantially rectangular. The shape of the mouth covering portion 11 may be other shapes such as a substantially elliptical shape. When the user wears the mask 10, one surface (surface S1 in FIG. 2 described later) of the mouth covering portion 11 is arranged to face the mouth and nose of the user, and the other surface (surface S1 in FIG. 2 described later) S2) is placed opposite the user.

The pair of string portions 12 are provided in loops on the short sides of the substantially rectangular mouth covering portion 11, for example. The pair of string portions 12 are hung on the left and right ears of the user, so that the mouth covering portion 11 is held in a position covering the user's mouth and nose. The material forming the mouth covering portion 11 and the material forming the string portion 12 may be different, and the mouth covering portion 11 and the string portion 12 may each be made of a plurality of materials.

(Conversation support device 20)
FIG. 2 shows an example of a cross-sectional configuration of the conversation support device 20 attached to the mask 10. As shown in FIG. The conversation support device 20 is attached to the mouth covering portion 11 of the mask 10 . Conversation support device 20 includes, for example, housing 21 , microphone 22 and speaker 23 housed in housing 21 , and holding member 24 holding housing 21 . Conversation support device 20, for example, further has an amplifier and a battery (not shown). The amplifier and battery are housed in housing 21 together with microphone 22 and speaker 23, for example. Here, the microphone 22 corresponds to a specific example of the acquisition section of the present invention.

The housing 21 has, for example, a tubular portion 21t and a widened portion 21w having a larger diameter than the tubular portion 21t. For example, a tubular portion 21t is provided to penetrate between one surface S1 of the mouth covering portion 11 and a surface S2 opposite to the surface S1, and a portion of the tubular portion 21t is arranged to protrude from the surface S1. there is The tubular portion 21t, for example, penetrates through the central portions of the surfaces S1 and S2. Since the conversation support device 20 has the housing 21 penetrating between the surfaces S1 and S2 of the mouth covering portion 11, for example, a microphone 22 is provided on the surface S1 side and a speaker is provided on the surface S2 side. 23 can be easily positioned. The widened portion 21w is connected to one end of the tubular portion 21t and arranged on the surface S2. For example, the microphone 22 is arranged near the other end of the tubular portion 21t, that is, the surface S1 side of the tubular portion 21t, and the speaker 23 is arranged in the widened portion 21w. The housing 21 may house either one of the microphone 22 and the speaker 23 .

A microphone 22 housed in the housing 21 acquires the first voice V1 uttered by the user wearing the mask 10 . The microphone 22 acquires, for example, the first voice V1 mainly emitted from the user's mouth. By arranging the microphone 22 on the mouth covering portion 11, it becomes possible to acquire the first voice V1 more efficiently. The microphone 22 does not have to be provided inside the housing 21 .

In this embodiment, since the microphone 22 is provided on the mask 10, the first voice V1 can be acquired by the microphone 22. FIG. Conversation support device 20 , for example, generates first voice information corresponding to first voice V<b>1 and transmits it to information processing device 30 . In the information processing device 30 , conversation support processing is performed on the first voice information acquired from the conversation support device 20 . Although the details will be described later, this makes it possible to facilitate conversational communication when wearing the mask 10 .

The microphone 22 is configured to be disposable together with the mask 10, for example, and is discarded after being used once to several times. Since the microphone 22 placed near the user's mouth and nose is disposable, it is possible to further enhance the effect of preventing infectious diseases. In addition to the microphone 22, other components of the conversation support device 20 may be disposable, or the entire conversation support device 20 may be disposable. A part or all of the configuration of conversation support device 20 may be used repeatedly.

The speaker 23 outputs a second sound V2 corresponding to the first sound V1 acquired by the microphone 22. FIG. The second voice V2 output from the speaker 23 is subjected to, for example, conversation support processing by the information processing device 30, and the volume of the second voice V2 is higher than the volume of the first voice V1. The processing performed by the information processing device 30 will be described later. The second sound V2 output from the speaker 23 may be processed by an amplifier. The speaker 23 may not be provided inside the housing 21 .

Power is supplied to these microphone 22 and speaker 23 from, for example, a battery. The battery is configured, for example, to start supplying power to the microphone 22 and the speaker 23 when the conversation support device 20 is attached to the mask 10 . This battery is configured using, for example, an air battery, and starts supplying power to the microphone 22 and the speaker 23 upon contact with oxygen in the air. The battery is configured to be able to continue supplying power to the microphone 22 and the speaker 23 for about 24 hours, for example.

The holding member 24 holds, for example, a tubular portion 21t protruding from the surface S1 of the mouth covering portion 11. As shown in FIG. As a result, the microphone 22 and the speaker 23 are fixed at predetermined positions on the mouth covering portion 11, and the first voice V1 is efficiently acquired and the second voice V2 is output. The holding member 24 has, for example, an annular shape, and is held by inserting the end of the tubular portion 21t into a hole in the center of the holding member 24. As shown in FIG. The hole diameter of the holding member 24, for example, increases with distance from the surface S1. The holding member 24 may have any other shape as long as it can hold the housing 21 . For example, the holding member 24 may be clip-shaped or the like. The holding member 24 may hold the microphone 22 or the speaker 23 directly. Note that the method of fixing the conversation support device 20 to the mask 10 is not limited to the above example. Conversation support device 20 may be fixed to mask 10 by, for example, an adhesive tape, hook-and-loop fastener, or the like. Conversation support device 20 can be attached by providing a pocket in mask 10 and accommodating conversation support device 20 in the pocket. It may be fixed to the mask 10 . Also in this case, it is preferable that the microphone 22 is arranged facing the user side of the mask 10 and the speaker 23 is arranged facing the side of the mask 10 opposite to the user.

(Information processing device 30)
FIG. 3 is a block diagram showing a schematic configuration of the information processing device 30. As shown in FIG. Information processing device 30 is connected to conversation support device 20 via wired or wireless communication, for example, via a network. The information processing device 30 has a CPU (Central Processing Unit) 31 , a ROM (Read Only Memory) 32 , a RAM (Random Access Memory) 33 , a storage 34 , a communication interface 35 , a display section 36 , an operation section 37 and a speaker 38 . Each component is communicatively connected to each other via a bus 39 .

The CPU 31 performs control of the above components and various arithmetic processing according to programs recorded in the ROM 32 or the storage 34 . Specific functions of the CPU 31 will be described later. The ROM 32 stores various programs and various data. RAM 33 temporarily stores programs and data as a work area.

The storage 34 stores various programs including an operating system and various data. For example, the storage 34 is installed with an application for transmitting/receiving various types of information to/from another device, and for determining results to be output based on various types of information acquired from other devices.

The communication interface 35 is an interface for communicating with other devices. As the communication interface 35, a wired or wireless communication interface according to various standards is used.

The display unit 36 is, for example, a display, and displays information regarding the conversation support device 20 and various types of information regarding online conferences and the like.

The operation unit 37 is, for example, a mouse and a keyboard, and receives operations or instructions from the user. The operation unit 37 may be implemented by configuring the display unit 36 with a touch panel display.

The speaker 38 outputs sound such as voice. For example, speaker 38 outputs the voices of other participants in the online conference. The speaker 38 is connected to the conversation support device 20 through wired or wireless communication, and may output the second voice V2 in place of the speaker 23 of the conversation support device 20 .

FIG. 4 shows an example of the functional configuration of the information processing device 30, and FIG. The information processing device 30 functions as an information acquisition unit 311, a support execution unit 312, and an output unit 313 by the CPU 31 reading programs stored in the storage 34 and executing processing (FIG. 4). Here, the support execution unit 312 corresponds to a specific example of the first support execution unit of the present invention. Conversation support processing executed in the information processing apparatus 30 will be described below with reference to FIGS. 4 and 5. FIG.

First, the information acquisition unit 311 acquires the first voice information corresponding to the user's first voice V1 acquired by the microphone 22 from the conversation support device 20 (step S101 in FIG. 5). The first voice information acquired by the information acquisition unit 311 includes, for example, information regarding the volume and frequency of the user's first voice V1.

After the information acquisition unit 311 acquires the first voice information, the assistance execution unit 312 determines the volume of the second voice V2 output from the speaker 23 according to the volume of the first voice V1 (see FIG. 5). step S102). At this time, for example, when the volume of the first voice V1 is lower than a predetermined volume, the assistance execution unit 312 determines the volume of the second voice V2 so as to be higher than the volume of the first voice V1. On the other hand, when the volume of the first voice V1 is equal to or higher than the predetermined volume, the assistance execution unit 312 determines the volume of the second voice V2 to be the same as the volume of the first voice V1. Here, since the assistance execution unit 312 determines the volume of the second voice V2 in this way, even if the volume of the first voice V1 uttered by the user is low, the volume of the first voice V1 output from the speaker 23 is reduced. The volume of the second voice V2 is increased, making it easier for the user's voice to reach the other party. The predetermined volume used by the assistance execution unit 312 is, for example, set in advance by the user and stored in the storage 34 or the like.

After the volume of the second voice V2 is determined by the assistance execution unit 312, the output unit 313 outputs the second voice information including the information on the volume determined by the assistance execution unit 312 to the conversation assistance device 20 ( Step S103 in FIG. 5). As a result, the second voice V2 having the volume determined by the assistance execution unit 312 is output from the speaker 23 . The output unit 313 may output the second audio information to the speaker 38, for example. As a result, the second voice V2 is output from the speaker 38. FIG.

Alternatively, when the user of the conversation support system 1 is a participant in the online conference, the second voice V2 may be output from speakers used by other participants in the online conference. For example, the second voice information is transmitted from the information processing device 30 via the network to the information processing device used by another participant in the online conference, and the second voice V2 is output from the speaker of this information processing device. At this time, the second voice V2 is not output near the user of the conversation support system 1, for example. As a result, for example, it is possible to prevent the leakage of the content of the conference.

After the process of step S103, the information processing apparatus 30 determines whether or not an instruction to end the process has been received (step S104 in FIG. 5). If it returns and accepts (step S104: YES), the process ends.

Note that the information processing apparatus 30 may output voice information from the output unit 313 to the speaker 38 by adjusting not only the volume but also the range and voice quality that are easy for the other party to hear. In addition, noise that reduces noise by separating sounds from the external environment around the place where the conversation is being held or noise from the equipment used for communication from the speech of the conversation and generating the opposite phase that cancels out the noise. A cancel function may be provided. This makes it possible to communicate more smoothly even when wearing a mask.

[Effects of Conversation Support Device 20 and Conversation Support System 1]
In the conversation support device 20 and the conversation support system 1 of the present embodiment, the microphone 22 that acquires the first voice V1 of the user is provided in the mouth covering part 11, so that Conversation assistance is provided. This makes it possible to facilitate communication when wearing the mask 10 . This function and effect will be described in detail below.

When the mask wearer utters a voice, the transmission of the voice is blocked by the mask, and there is a risk that the voice will be quieter or the utterance will be unclear compared to when the mask is not worn. There is For example, if such a phenomenon occurs in non-face-to-face communication such as online meetings and teleconferences, the contents of the speech of the person wearing the mask cannot be conveyed well to the listener, which may hinder work. In addition, there are many people wearing masks in the medical field, and communication problems caused by wearing masks tend to become noticeable.

Furthermore, in order to accurately grasp the speech content of the mask wearer, it is necessary to confirm the content from the listener to the speaker, which takes time. In addition, when the position of the speaker and the listener is different, such as when the patient confirms the content of the utterance with the doctor, or when the subordinate confirms the content of the utterance with the superior, the listener is asked to confirm the content of the utterance. easily hesitated.

If the speaker removes the mask and speaks or speaks loudly in order to accurately convey the content of the speech, there is a risk that the effectiveness of the mask in preventing infectious diseases will diminish. .

In particular, as of January 2021, the number of people wearing masks is increasing due to the effects of the new coronavirus infection (COVID-19), which has continued to spread since around January 2020. Communication problems are likely to occur.

On the other hand, in the conversation support system 1, since the microphone 22 is attached to the mouth covering portion 11 of the mask 10, the first voice V1 of the user is acquired by the microphone 22, and the first voice V1 is used for conversation support. The processed second voice V2 is output from speaker 23 of conversation support device 20 or speaker 38 of information processing device 30 . Specifically, when the volume of the first audio V1 is smaller than a predetermined volume, the processing by the information processing device 30 is performed so that the volume of the second audio V2 becomes higher than the volume of the first audio V1. Therefore, even if the user speaks while wearing the mask 10, the contents of the speech can easily reach the listener, and communication by conversation proceeds smoothly.

In addition, since the speaker 23 is provided on the surface (surface S2) opposite to the surface S1 of the mask 10 on which the microphone 22 is provided, the second sound V2 output from the speaker 23 is not blocked by the mask 10. delivered to the listener without Similarly, the second voice V2 output from the speaker 38 of the information processing device 30 is also delivered to the listener without being blocked by the mask 10 .

As described above, in the conversation support device 20 and the conversation support system 1 of the present embodiment, the mouth covering portion 11 is provided with the microphone 22 for acquiring the first voice V1 of the user, and the volume of the first voice V1 is is small, the second sound V2 with a higher volume is output from the speaker 23 or the speaker 38. Therefore, even when wearing the mask 10, the content of the user's speech can easily reach the listener, making it possible to proceed with communication more smoothly.

Another embodiment of the conversation support system 1 described in the first embodiment will be described below. In the following description, in order to avoid duplication of description, detailed descriptions of the same configurations as those of the conversation support system 1 described in the first embodiment will be omitted.

<Second embodiment>
In the conversation support system 1, in addition to the conversation support described in the first embodiment, or instead of the conversation support described in the first embodiment, other conversation support processing may be performed. For example, when the volume of the user's first voice V1 is smaller than a predetermined volume, the conversation support system 1 may notify the user of a warning. Here, the assistance execution section of the conversation support system 1 according to the second embodiment corresponds to a specific example of the second assistance execution section of the present invention. Except for this point, the conversation support system 1 described in the second embodiment has the same configuration as the conversation support system 1 described in the first embodiment, and has the same effects.

FIG. 6 is a flowchart showing an example of the procedure of conversation support processing executed in the information processing apparatus 30 according to the present embodiment.

First, the information processing device 30 acquires the first voice information corresponding to the user's first voice V1 acquired by the microphone 22 from the conversation support device 20 (step S201).

Next, the information processing device 30 determines whether or not the volume of the first voice V1 is less than a predetermined value (step S202). When the volume of the first voice V1 is less than the predetermined value (step S202: YES), the information processing device 30 instructs the notification unit to notify. This notification unit includes, for example, at least one of display unit 36 and speaker 38 of information processing device 30 .

The notification unit that has received the notification instruction displays, for example, a message such as "Your voice is low", "Please raise your voice" and "Insufficient volume", or an image representing such a message on the display unit 36. Notify by displaying. The display unit 36 may display another message that alerts the user to the volume of the voice to be uttered (the first voice V1), or warns the user about the volume of the first voice V1. An image or the like for prompting arousal may be displayed.

The notification unit that has received the notification instruction may output a sound such as a warning sound from the speaker 38 to make the notification. The notification unit may notify using both the display unit 36 and the speaker 38 .

After instructing the notification, the information processing device 30 outputs the second audio information based on the first audio information acquired in step S201 (step S204). At this time, the second audio information output by the information processing device 30 may be subjected to the same processing as described in the first embodiment (see FIG. 5). After performing the process of step S204, the information processing apparatus 30 proceeds to the process of step S205.

On the other hand, when the volume of the first voice V1 is equal to or greater than the predetermined value (step S202: NO), the information processing device 30 outputs the second voice information without instructing notification (step S204).

After the process of step S204, the information processing apparatus 30 determines whether or not an instruction to end the process has been received (step S205). If so (step S205: YES), the process ends.

As described above, in the conversation support system 1 according to the present embodiment, the microphone 22 for acquiring the first voice V1 uttered by the user is provided in the mouth covering portion 11, and when the volume of the first voice V1 is low, The user is alerted via the notification unit. As a result, the user can speak while paying attention to the volume, and communication can proceed more smoothly. Such a function is particularly effective in situations where the user is in a higher position than the listener, and the listener is unlikely to point out to the user that the voice is low.

<Third Embodiment>
The conversation support system 1 may, for example, selectively output the second voice V2 according to the volume of the user's first voice V1. For example, the conversation support system 1 selectively outputs the second voice V2 when the volume of the first voice V1 is greater than a predetermined volume. Here, the support execution section of the conversation support system 1 according to the third embodiment corresponds to a specific example of the third support execution section of the present invention. Except for this point, the conversation support system 1 described in the third embodiment has the same configuration as the conversation support system 1 described in the first embodiment, and has the same effects.

FIG. 7 is a flowchart showing an example of the procedure of conversation support processing executed in the information processing apparatus 30 according to the present embodiment.

First, the information processing device 30 acquires, from the conversation support device 20, first voice information corresponding to the user's first voice V1 acquired by the microphone 22 (step S301).

Next, the information processing device 30 determines whether or not the volume of the first voice V1 exceeds a predetermined value (step S302). When the volume of the first sound V1 exceeds the predetermined value (step S302: YES), the information processing device 30 outputs second sound information based on the first sound information acquired in step S301 (step S303). . At this time, the second audio information output by the information processing device 30 may be subjected to the same processing as described in the first embodiment (see FIG. 5).

After performing the process of step S303, the information processing apparatus 30 determines whether or not an instruction to end the process is accepted (step S304), and if not accepted (step S304: NO), returns to the process of step S301. , if received (step S304: YES), the process is terminated.

On the other hand, when the volume of the first voice V1 is equal to or less than the predetermined value (step S302: NO), the information processing device 30 proceeds to the process of step S304 without outputting the second voice information.

As described above, in the conversation support system 1 according to the present embodiment, the mouth covering portion 11 is provided with the microphone 22 for acquiring the first voice V1 uttered by the user. 2 Do not output voice V2. This makes it possible to selectively output the second voice V2 while the user is consciously speaking. Therefore, the noise contained in the voice reaching the listener is reduced, making it possible to proceed with communication more smoothly.

In addition, when conducting a conference using a video conference system, the person who is not speaking may turn off the microphone so that noise is not output from the speaker of the listener, and it is not recommended to turn on the microphone when trying to speak. Although the speaker's voice may not be output from the speaker on the listening side due to forgetting, according to the conversation support system 1 according to the present embodiment, when the user speaks, the speaker's voice is automatically output from the speaker on the listening side. Since audio output is started, the video conference can be held smoothly.
