Then, the access control unit 111 transmits an authentication request to the conference support server 20. This authentication request includes the audio data acquired by the microphone 10b.

  Next, the control part 21 of the meeting assistance server 20 performs a user authentication process (step S1-4). Specifically, the user authentication unit 211 of the control unit 21 extracts a voiceprint using audio data acquired from the tablet terminal 10. Then, the user authentication unit 211 searches the user management information storage unit 22 for a user management record 220 in which the extracted voiceprint is recorded. Here, when the user management record 220 in which the extracted voiceprint is recorded cannot be specified, the user authentication unit 211 denies access.

  On the other hand, when the user management record 220 in which the extracted voiceprint is recorded is specified and the user authentication is completed, the user authentication unit 211 specifies the user ID recorded in the user management record 220. Then, the user authentication unit 211 transmits a menu screen to the tablet terminal 10. This menu screen includes a material advance confirmation button and a conference participation button. Here, the material prior confirmation button is selected.

  The control unit 21 of the conference support server 20 that has detected the selection of the document pre-confirmation button executes conference document identification processing (step S1-5). Specifically, the material providing unit 212 of the control unit 21 searches the conference management storage unit 23 for the conference management record 230 in which the user ID of the user who has been authenticated is recorded in the participant data area. Then, the material providing unit 212 generates a conference list screen including a list of conference IDs of the extracted conference management record 230, and outputs the conference list screen to the touch panel display 10a of the tablet terminal 10. The user selects a conference that he / she wishes to browse materials on the conference list screen displayed on the touch panel display 10a. In this case, the material display control unit 112 of the control unit 11 transmits a material display request to the conference support server 20. This material display request includes data related to the conference ID of the conference selected on the conference list screen. Then, the material provision unit 212 of the control unit 21 of the conference support server 20 extracts the conference material file of the conference material management data 240 in which the acquired conference ID is recorded from the material management information storage unit 24 as a provision target.

  Next, the control part 21 of the meeting assistance server 20 performs the extraction process of a registered memo (step S1-6). Specifically, the material providing unit 212 of the control unit 21 searches the memo management information storage unit 25 for a memo management record 250 in which the user ID that has been authenticated by the user and the material ID to be provided are recorded. Here, when the memo management record 250 can be extracted, the material providing unit 212 displays the memo content on the page and coordinates recorded in the memo management record 250 in the conference material file of the conference material management data 240 identified by the material ID. Set to display the memo pad icon including. The memo contents of the memo management record 250 are embedded in this icon. If the memo management record 250 cannot be extracted, no memo is set.

  Next, the control unit 21 of the conference support server 20 executes a document providing process (step S1-7). Specifically, the material providing unit 212 of the control unit 21 transmits the conference material file with the memo attached to the tablet terminal 10 together with the material ID.

  The control unit 11 of the tablet terminal 10 that has received the conference material file executes a material display process (step S1-8). Specifically, the material display control means 112 of the control unit 11 displays the conference material file acquired from the conference support server 20 on the touch panel display 10a. In this case, as shown in FIG. 5, the meeting material file is displayed on the touch panel display 10a. Further, a memo button 101 for attaching a memo to this material is displayed on the touch panel display 10a. When a registered memo is pasted, a memo pad icon to be described later is displayed at the memo pasting position of the conference material file.

Then, the user confirms the content of the conference material file displayed on the touch panel display 10a. When leaving a memo in the document, the memo button 101 is selected. In this case, an input selection screen including a button for selecting handwriting input or voice input is displayed.
And when creating a memo by handwriting, after selecting a handwriting input button on the input selection screen, the touch position on the touch panel display 10a is touched (panel touch).

  When the handwriting input button is selected and a panel touch is detected, the control unit 11 of the tablet terminal 10 executes a touch input process (step S1-9). Specifically, the material display control unit 112 of the control unit 11 activates the handwriting input unit 113. And the handwriting input means 113 provides an upper layer in the touch position on the meeting material displayed on the touch panel display 10a, and outputs the transparent handwriting input screen 102 to this upper layer. The handwriting input screen 102 can be handwritten by touch input using a stylus or the like. When the paste button on the handwriting input screen 102 is selected, the handwriting input unit 113 creates image data of the contents input by handwriting. Then, the material display control unit 112 activates the memo pasting unit 115. In this case, the memo pasting unit 115 reduces the size of the handwriting input screen 102 to the size of the memo pad icon 103 and displays it on the panel touched position. By selecting the memo pad icon 103, the image data can be expanded on the upper layer of the conference material file displayed on the touch panel display 10a.

When starting the conference, the facilitator using the parent device performs recording start input at the tablet terminal 10. In this case, the control unit 11 of the parent tablet terminal 10 executes a recording start instruction process (step S2-10). Specifically, the recording control means 116 of the control unit 11 transmits a recording start instruction to the tablet terminal 10 of the slave unit via the wireless communication unit 10c.

  The control unit 11 of the tablet device 10 of the parent device that has transmitted the recording start instruction and the slave device that has received the recording start instruction starts the recording process (step S2-11). Specifically, the recording control unit 116 of the control unit 11 generates a recording file in which sound collected using the microphone 10b is recorded in time series.

  Then, when ending the conference, the facilitator using the parent device performs recording end input at the tablet terminal 10. In this case, the control unit 11 of the parent tablet terminal 10 executes a recording end instruction process (step S2-12). Specifically, the recording control means 116 of the control unit 11 transmits a recording end instruction to the tablet terminal 10 of the slave unit via the wireless communication unit 10c.

  Then, the recording control means 116 of the control unit 11 of the tablet terminal 10 of the master unit that has transmitted the recording end instruction and the slave unit that has received the recording end instruction stops recording and stores the generated recording file in the recording storage unit 13. Record. In this case, the recording control unit 116 records the conference ID selected on the conference list screen in association with the recording file.

  Next, the control unit 21 of the conference support server 20 executes recording file collection processing (step S2-13). Specifically, the minutes creation unit 215 of the control unit 21 collects a recording file associated with the conference ID from the recording storage unit 13 of each tablet terminal 10. Then, the minutes creation unit 215 records the recording management data 260 including the recording file in association with the terminal ID and the conference ID of the tablet terminal 10 that collected the recording file in the recording management storage unit 26.

  Next, the control part 21 of the meeting assistance server 20 performs a minutes creation process (step S2-14). Specifically, the minutes creation means 215 of the control unit 21 creates the minutes using the recorded files collected from the tablet terminals 10 of the participants. This process will be described in detail below.

(Meeting process)
Next, the minutes creation process will be described with reference to FIGS. In the present embodiment, the meeting support server 20 creates the minutes by voice recognition processing using the recording file of the meeting for which the minutes are to be created. Here, recording files collected from a plurality of tablet terminals 10 are used for a meeting for which minutes are to be created.

  First, the control part 21 of the meeting assistance server 20 performs the time synchronization process of the recording file acquired from each terminal (step S3-1). Specifically, the minutes creation unit 215 of the control unit 21 acquires a recording file in which the meeting ID for which the minutes are to be recorded is recorded from the recording management storage unit 26. Then, the minutes creation means 215 synchronizes the recording files by matching the start times. Here, as shown in FIG. 8, it is assumed that minutes are created using recording files acquired from a plurality of tablet terminals (A, B, C), and the start times on the time axis are synchronized to synchronize. Let

  Next, the control part 21 of the meeting assistance server 20 performs the specific process of the audio | voice of the maximum volume at each time (step S3-2). Specifically, the voice filter unit 216 of the control unit 21 compares the volume of each recording file collected from the tablet terminal 10 at each time of a predetermined time interval from the start time. Here, as shown in FIG. 8, the wave height (volume level) in each recording file collected from the tablet terminals (A, B, C) is compared. Then, for each time, a file in which the maximum volume is recorded at each volume at the same time is specified based on the comparison result. In each recording file, the time range in which the maximum volume is recorded is specified and temporarily stored as an area (“maximum area”) in which the voice of the user of each tablet terminal 10 is recorded.

Then, the following processing is repeated for each recording file.
Here, first, the control unit 21 of the conference support server 20 executes a filtering process (step S3-3). Specifically, the voice filter unit 216 of the control unit 21 specifies the “maximum area” temporarily stored in a recording file (other recording files) other than the recording file to be processed. Then, the voice filter unit 216 reduces the waveform of the “maximum area” of another recording file and performs fitting so as to match the waveform of the recording file to be processed. Then, the audio filter unit 216 newly generates a recording file obtained by subtracting the fitted waveform from the waveform of the recording file to be processed. As a result, as shown in FIG. 9, noise cancellation (erasure of the voice of the user of the other tablet terminal 10) is performed using the waveform of the “maximum area” recorded in another recording file. As a result, as shown in FIG. 10, it is possible to generate a recording file in which a sound other than the time range of the “maximum area” is deleted in the waveform of the recording file to be processed.

  Next, the control part 21 of the meeting assistance server 20 performs the speech recognition process by the filtered voice (step S3-4). Specifically, the voice recognition unit 217 of the control unit 21 acquires the filtered recording file from the voice filter unit 216. The voice recognition unit 217 generates a recognition result (text) in the “maximum area” by performing voice recognition processing using the recorded file.

Next, the control part 21 of the meeting assistance server 20 performs the recording process of a voice recognition result (step S3-5). Specifically, the minutes creation unit 215 of the control unit 21 records the recognition result in association with the conference ID, the terminal ID of the tablet terminal that acquired the recording file, the user ID, and the time range of “maximum area”. A voice recognition result record 270 is generated and recorded in the voice recognition result storage unit 27. Furthermore, the minutes creation unit 215 extracts the conference management record 230 in which the identified conference ID and terminal ID are recorded in the conference ID data area and the used terminal data area from the meeting management storage unit 23, respectively. Then, the minutes creation means 215 acquires the user ID recorded in the participant data area of the conference management record 230 and records it in the voice recognition result record 270.
The above processing is repeated for each recording file in which the conference ID to be processed is recorded.

  Next, the control unit 21 of the conference support server 20 executes a minutes registration process (step S3-6). Specifically, the minutes creation unit 215 of the control unit 21 rearranges the voice recognition result records 270 in the order from the earliest start time of the time range in the voice recognition result records 270 in which the conference IDs to be processed are recorded. Next, the minutes creation unit 215 creates a minutes file by combining the recognition results associated with the user IDs in this order. Then, the minutes creation means 215 records the minutes in the minutes storage unit 28 in association with the minutes file.

As described above, according to the present embodiment, the following effects can be obtained.
(1) In the above embodiment, in the prior confirmation process, the control unit 21 of the conference support server 20 executes a document providing process (step S1-7). The control unit 11 of the tablet terminal 10 that has received the conference material file executes a material display process (step S1-8). And the control part 11 of the tablet terminal 10 performs a touch input process (step S1-9) and an audio | voice input process (step S1-10). And the control part 11 of the tablet terminal 10 performs a memo registration request process (step S1-11). In the meeting holding process, the control unit 21 of the meeting support server 20 executes a user authentication process (step S2-4), an already registered memo extraction process (step S2-7), and a document provision process (step S2). -8) is executed. And the control part 11 of the tablet terminal 10 performs a document display process (step S2-9). Thereby, it is possible to confirm the conference material in advance and attach a memo to the conference material. Therefore, it is possible to prepare a question content and confirmation items in advance using a memo and efficiently hold a meeting.

  (2) In the above embodiment, the control unit 11 of the tablet terminal 10 executes touch input processing (step S1-9). Thereby, a memo can be left by handwriting. Furthermore, the control part 11 of the tablet terminal 10 performs an audio | voice input process (step S1-10). Thereby, a memo can be left by voice recognition.

  When the paste button is selected, the handwriting input screen 102 or the voice input screen 104 is reduced to the size of the memo pad icon (103, 105) and displayed at the position touched on the panel after the selection of the handwriting input button or the voice input button. Let Thereby, in touch panel display 10a, the presence or absence of a memo can be determined by the icon. Furthermore, when the display of the memo is unnecessary, the conference material file can be browsed in a state where the memo is not displayed.

  (3) In the said embodiment, the control part 21 of the meeting assistance server 20 performs the setting process of a main | base station or a subunit | mobile_unit (step S2-6). Thereby, in a meeting in which a plurality of users participate, authority can be given to the tablet terminal 10 according to the role of the users. Therefore, the tablet terminal 10 used by other participants can be controlled using the tablet terminal 10 used by the user of the facilitator.

  (4) In the above embodiment, when starting a conference, the facilitator using the parent device performs recording start input at the tablet terminal 10. In this case, the control unit 11 of the parent tablet terminal 10 executes a recording start instruction process (step S2-10). Then, the control unit 11 of the parent terminal that has transmitted the recording start instruction and the slave terminal 10 that has received the recording start instruction starts the recording process (step S2-11). Thereby, recording can be started at the same time on the plurality of tablet terminals 10 used by the participants of the conference. Therefore, even when the time of the local timer of each tablet terminal 10 is shifted, recording is started at the same time, so that minutes can be created by synchronizing time in a plurality of recording files. .

  (5) In the said embodiment, the control part 21 of the meeting assistance server 20 performs the specific process (step S3-2) of the audio | voice of the maximum sound volume at each time, and a speech recognition process (step S3-4). And the control part 21 of the meeting assistance server 20 performs the recording process of a speech recognition result (step S3-5). Since the microphone 10b of his / her tablet terminal 10 is the closest to the user, the user's voice is recorded at the maximum volume on his / her tablet terminal 10. Therefore, the voice of the user of the tablet terminal 10 can be specified by the volume.

  Moreover, the control part 21 of the meeting assistance server 20 performs a filtering process (step S3-3), and performs the audio | voice recognition process (step S3-4) by the filtered audio | voice. In a conference in which a plurality of users participate, voices of other participants may be mixed in the microphone 10b of the tablet terminal 10. In such a case, the voice of the user mixed in the recording file of the other tablet terminal 10 can be deleted using the voice of the user of each tablet terminal 10. Therefore, only the voice of the user of the tablet terminal 10 can be extracted, and voice recognition can be performed accurately.

  (6) In the above-described embodiment, the control unit 21 of the conference support server 20 performs a voice recognition result recording process (step S3-5). Specifically, the minutes creation unit 215 of the control unit 21 records the recognition result in association with the conference ID, the terminal ID of the tablet terminal that acquired the recording file, the user ID, and the time range of “maximum area”. The voice recognition result record 270 is recorded in the voice recognition result storage unit 27. By using this time range, the order of speech can be specified and the minutes can be created.

In addition, you may change the said embodiment into the following aspects.
In the above embodiment, the tablet terminal 10 is used as a client terminal to perform a prior confirmation process and a process at the time of holding a meeting. The client terminal is not limited to the tablet terminal 10, and a desktop terminal, a notebook personal computer, or the like can also be used. It is also possible to use different computer terminals for the client terminal used for the prior confirmation process and the client terminal used for the process at the time of the conference.

  In the above embodiment, the control unit 21 of the conference support server 20 in the prior confirmation process or the process at the time of holding the conference, the registered memo extraction process (steps S1-6, S2-7), the document provision process (step S1) -7, S2-8). Here, a memo may be displayed even when the conference material file has been revised after the prior confirmation and before the conference. In this case, the material management information storage unit 24 stores revision information that associates the material ID of the old conference material file with the material ID of the revised conference material file. Further, in this revision information, a page changed by revision, a coordinate area of the revision location, and a new / old page correspondence table when a page is moved are recorded.

  Then, when the material providing unit 212 of the control unit 21 specifies the conference material file to be provided, the material providing unit 212 confirms the presence or absence of the revision using the revision information. If there is no revision, the material providing unit 212 transmits the conference material file with the memo attached thereto to the tablet terminal 10.

  On the other hand, when the revision is made, the material providing unit 212 identifies the material ID of the revised conference material file with respect to the material ID of the conference material file to which the memo is attached. Next, the material providing unit 212 uses the revision information to determine whether the page and coordinate area of the conference material file recorded in the memo management record 250 have been revised.

  If the page in the revised meeting material file is identified using the old and new page correspondence table and the coordinate area of the page to which the memo is attached has not been revised, the material providing means 212 will read the memo in the new page. A memo is attached to the coordinates recorded in the management record 250.

  On the other hand, when the coordinate area where the memo was pasted has been revised, or when the page where the memo was pasted has been deleted, the material providing unit 212 includes a caution including the memo in the conference material file. Attach information. Then, the material providing unit 212 transmits the conference material file to which the memo and the attention information are added to the tablet terminal 10. Thereby, even when the meeting material file is revised, the user can be alerted or the memo can be used effectively.

  In the above-described embodiment, in the minutes creation process, the control unit 21 of the meeting support server 20 executes the process of specifying the maximum sound volume at each time (step S3-2). Thereby, the sound of the maximum volume is specified as the sound of the user of the tablet terminal 10. The method for identifying the voice of the user of each tablet terminal 10 is not limited to this. For example, the voice print of the user of the tablet terminal 10 may be acquired from the user management information storage unit 22 and only the voice of this voice print may be extracted from the recording file. Thereby, the voice contained in the recording data is filtered using the voice print of the user.

  In the above embodiment, in the minutes creation process, the control unit 21 of the meeting support server 20 executes a filtering process (step S3-3). Here, the voice of the user of one tablet terminal 10 is extracted for each recording file. And the control part 21 of the meeting assistance server 20 performs the speech recognition process by the filtered audio | voice (step S3-4). In addition, voices of a plurality of users who use one tablet terminal 10 may be separated by using a voice print. This process will be described with reference to FIG.

  In this process, the control unit 21 of the conference support server 20 performs the time synchronization process (step S4-1) of the recording file acquired from each terminal, as in steps S3-1 to S3-3. The maximum volume sound specifying process (step S4-2) and the filtering process (step S4-3) are executed.

  Next, the control part 21 of the meeting assistance server 20 performs a voiceprint confirmation process (step S4-4). Specifically, the minutes creation unit 215 of the control unit 21 uses the terminal ID associated with the recording file to be processed in the participant data area of the conference management record 230 recorded in the conference management storage unit 23. The recorded user ID is acquired. Then, the minutes creation unit 215 extracts the user management record 220 in which the user ID is recorded in the user management information storage unit 22 and acquires the voiceprint of the user of the tablet terminal 10. Then, the minutes creation means 215 confirms the voiceprint for the “maximum area” voice.

  Next, the control part 21 of the meeting assistance server 20 performs the determination process about whether the voice other than the person is included (step S4-5). Specifically, the minutes creation means 215 of the control unit 21 determines that the voice other than the user is not included when the voice other than the voice print of the user of the tablet terminal 10 is not included.

  When it is determined that the voice other than the user is not included (in the case of “NO” in step S4-5), the control unit 21 of the conference support server 20 is filtered in the same manner as in steps S3-4 and S3-5. A voice recognition process using voice (step S4-6) and a voice recognition result recording process (step S4-7) are executed.

  On the other hand, if it is determined that the voice of a voiceprint other than the user is included (“YES” in step S4-5), the control unit 21 of the conference support server 20 The separation process is executed (step S4-8). Specifically, the voice filter unit 216 of the control unit 21 generates a recording file in which the voice of the user himself / herself is extracted from the filtered recording file using the voice print of the user of the tablet terminal 10. Furthermore, the voice filter unit 216 generates a new recording file in which the voice of the user himself / herself specified using the voiceprint is deleted from the filtered recording file. From these recorded files, the voice filter unit 216 identifies the remaining voice as the voice of the other person, thereby separating the voice of the user from the voice of the other person.

  Next, the control part 21 of the meeting assistance server 20 performs a voice recognition process with the separated voice (step S4-9). Specifically, the voice recognition unit 217 of the control unit 21 acquires the separated user's voice and residual voice from the voice filter unit 216, and executes voice recognition processing on these voices.

  Next, the control unit 21 of the conference support server 20 executes a voice recognition result recording process (step S4-7). Specifically, the minutes creation means 215 of the control unit 21 records the recognition result in association with the conference ID, the terminal ID of the tablet terminal that acquired the recording file, the time range of the “maximum area”, and the terminal ID. The recognition result record 270 is recorded in the voice recognition result storage unit 27. In this case, the minutes creation unit 215 records the user ID in the voice recognition result record 270 for the voice of the user of the tablet terminal 10. On the other hand, for the voice of another person other than the user of the tablet terminal 10, the “other participant” flag is recorded in the user ID data area of the voice recognition result record 270.

The above processing is repeated for each recording file.
And the control part 21 of the meeting assistance server 20 performs the registration process of the minutes similarly to step S3-6 (step S4-10).

Thereby, the voice of the user of the tablet terminal 10 can be specified using the voiceprint, and the minutes can be created.
Furthermore, a single tablet terminal 10 can be shared by a plurality of users by using a voiceprint. In this case, the voice of the “maximum area” is separated for each user using a voiceprint, and the voice recognition process is executed.

  In the above embodiment, the control unit 11 of the tablet device 10 of the parent device that has transmitted the recording start instruction and the slave device that has received the recording start instruction performs the recording process (step S2-11). In this case, the tablet terminal 10 may perform filtering of the user's voice. In this case, an audio filter unit is provided in the control unit 11 of the tablet terminal 10. When the conference support server 20 performs the user authentication process at the start of the conference, the conference support server 20 provides the voice print of the authenticated user to the tablet terminal 10. And the control part 11 of the tablet terminal 10 filters the audio | voice acquired in the microphone 10b using the voiceprint acquired from the meeting assistance server 20. FIG. Specifically, the control unit 11 of the tablet terminal 10 records only the voice that matches the voiceprint in the recording storage unit 13.

Furthermore, you may make it the control part 11 of the tablet terminal 10 perform a speech recognition process in the tablet terminal 10 based on the filtered voice.
In this case, the utterance time (elapsed time from the recording start instruction) is recorded for each voice recognition result. And the meeting assistance server 20 which acquired the speech recognition result from each tablet terminal 10 arranges a speech recognition result in order of utterance time, and produces the minutes. In this case, the user ID of the user of the tablet terminal 10 is recorded in association with each voice recognition result.

  In the above embodiment, a memo is attached to the conference material. Instead of or in addition to this, a sticky note for marking or a mark may be attached. In this case, it is not necessary to record the memo contents in the memo storage unit 12.

  In the above embodiment, by selecting the memo pad icon 103, the memo content is expanded to the upper layer of the conference material file displayed on the touch panel display 10a. Here, the memo content may be displayed on the memo pad icon 103. As a result, for simple memos, the memo contents can be grasped without expanding the memo pad icon 103.

  In the above embodiment, the control unit 21 of the conference support server 20 executes the registered memo extraction process (step S1-6). Specifically, the material providing unit 212 of the control unit 21 searches the memo management information storage unit 25 for a memo management record 250 in which the user ID that has been authenticated by the user and the material ID to be provided are recorded. Here, a memo attached to the document may be shared. Specifically, at the time of creating a memo, a designation for being a sharing target is input. In this case, the sharing flag is recorded in the user ID data area of the memo management record 250 of the memo management information storage unit 25. Then, in the registered memo extraction process (step S1-6), the memo management record 250 in which the shared flag is recorded is also extracted. Thereby, memo information can be shared between users.

  In the above embodiment, the control unit 21 of the conference support server 20 that has received the memo registration request executes a memo registration process (step S1-12). In addition, the memo management record 250 recorded in the memo management information storage unit 25 may be modified. Specifically, in the document display process (step S1-8) in the tablet terminal 10, when the memo contents and display position (coordinates) of the registered memo are corrected, the tablet terminal 10 determines the corrected memo and contents. And a memo registration request process including the display position (coordinates) (step S1-11). Thereby, the content and position of the already registered memo can be corrected later.

  In the embodiment described above, the control unit 21 of the conference support server 20 specifies the voice of the user of each tablet terminal 10 by specifying the maximum volume of voice at each time (step S3-2). The method for specifying the voice of the user of each tablet terminal 10 is not limited to the method using the maximum volume. For example, it is possible to specify a sound of a predetermined sound volume (threshold sound volume) or higher as the sound of the user of the tablet terminal 10.

  -In the said embodiment, the control part 21 of the meeting assistance server 20 performs a filtering process (step S3-3). Here, the “maximum area” waveform of another recording file is reduced, and fitting is performed so as to match the waveform of the recording file to be processed. In this case, a waveform obtained by multiplying a waveform included in a recording file of another tablet terminal 10 by a predetermined attenuation rate may be generated and subtracted from the waveform of the recording file to be processed. In this case, before the start of the conference, volume information is collected in which each user's voice is collected at each tablet terminal 10. Then, an attenuation rate is calculated by comparing the volume at which each user's voice is collected at the user's own tablet terminal 10 with the volume at which the other tablet terminal 10 collects the sound. Then, an attenuation table in which the attenuation rate is recorded in a matrix composed of the terminal ID of the user's own tablet terminal 10 and the terminal ID of the other tablet terminal 10 is created and held in the audio filter unit 216. .

When filtering the recording file to be processed, the voice filter unit 216 uses the recording management data 260 recorded in the recording management storage unit 26 to specify the terminal ID associated with the recording file to be processed. . Furthermore, the voice filter means 216 specifies a terminal ID associated with another recording file used for filtering. Next, the voice filter unit 216 acquires the attenuation rate from the attenuation table using the identified terminal ID. Then, the voice filter unit 216 generates a filtering waveform obtained by multiplying the waveform of the recording file recorded by each other tablet terminal 10 by the attenuation factor, and subtracts it from the waveform of the recording file to be processed. Thereby, filtering can be performed efficiently.
Furthermore, at the time of the filtering process, a voice about another user of the tablet terminal 10 may be extracted, and a filtering waveform obtained by multiplying the extracted voice waveform by an attenuation factor may be generated.
