[2.2. Operation]
The user of the learning system 2 accesses the web page of the business provider that provides the learning service by the learning system 2 in advance, for example, the microphone identification data of the microphone 13 owned by the user and the content identification of the DVD-ROM owned by the user. The data and the language in which the user wishes to perform pronunciation training and its level are registered in the server device 20.

  More specifically, the user connects the microphone 13 to the terminal device 11 and causes the terminal device 11 to read the microphone identification data, and then operates the keyboard 14 to read the microphone identification data read as the user identification data. 11 to the server device 20. Similarly, the user sets the DVD-ROM in the DVD-ROM drive 17 and causes the terminal device 11 to read the content identification data, and then operates the keyboard 14 to read the content identification data read from the terminal device 11 to the server device. 20 to send. When the user owns a plurality of DVD-ROMs, the user repeats the content identification data registration operation for each DVD-ROM. Further, after the user operates the keyboard 14 to input a language such as “English” and a level such as “low”, the language data and level data generated by the input are transferred from the terminal device 11 to the server device 20. Send it.

  As described above, the user identification data and content identification data transmitted from the terminal device 11 to the server device 20 are stored in the transmission history DB stored in the transmission history data storage unit 205e (see FIG. 11). Stored as identification data. If the user identification data has already been registered, the content identification data relating to the new registration is added to the owned content identification data column of the existing record.

  Further, the language data and the level data transmitted from the terminal device 11 to the server device 20 as described above are stored in the user attribute DB stored in the user attribute data storage unit 205d (see FIG. 10) together with the user identification data. The If the user identification data has already been registered, the language data and level data relating to the new registration are overwritten in the user attribute data column of the existing record.

  When the above registration work is completed, the user can use the learning system 2. When the user wants to perform pronunciation training, the user connects the microphone 13 to the terminal device 11. In response to the connection to the terminal device 11, the microphone 13 outputs microphone identification data to the terminal device 11, and the terminal device 11 uses the microphone identification data as user identification data for identifying a user who uses the terminal unit 10. 20 to send.

  When the user identification data is received by the server device 20, the control unit 201 obtains user attribute data corresponding to the received user identification data from the user attribute DB (see FIG. 10) stored in the user attribute data storage unit 205d. Search for. In addition, the control unit 201 searches for transmission history data corresponding to the received user identification data from the transmission history DB (see FIG. 11) stored in the transmission history data storage unit 205e.

The content attribute data including the language data and level data of the searched user attribute data is extracted from the selected content attribute DB.

  The control unit 201 searches each partial data ID included in the extracted content attribute data from the already transmitted partial data ID column of the searched transmission history data. If the search fails, it indicates that the read position instruction data corresponding to the partial data ID has never been transmitted from the server device 20 to the terminal device 11 used by the user in the past. On the other hand, when the search is successful, the control unit 201 reads the number of transmissions corresponding to the searched partial data ID in the transmission history data. The already transmitted number of times read out in such a manner indicates the number of times the corresponding read position instruction data has been transmitted to the terminal device 11 used by the user in the past.

  As described above, when the control unit 201 specifies the number of times the reading position instruction data corresponding to the extracted content attribute data has been transmitted to the terminal device 11 in the past, the control unit 201 is selected with a higher probability as the number is smaller. After the priority is given, a predetermined number, for example, 30 pieces of content attribute data are arbitrarily selected from the extracted content attribute data. The control unit 201 adds 1 to the number of transmissions of transmission history data corresponding to each selected content attribute data.

  When the control unit 201 selects the content attribute data as described above, the reading position instruction data and guidance data corresponding to the selected content attribute data are obtained as the reading position instruction DB (see FIG. 5) and the guidance DB (see FIG. 7). Are transmitted to the terminal device 11 together with the corresponding content identification data and partial data ID.

  When the terminal device 11 receives the read position instruction data and the guidance data from the server device 20, the terminal device 11 performs guidance display, image display by reproducing the DVD-ROM, and sound generation control according to them. At that time, the terminal device 11 causes the display 15 to display on the display 15 instructing the user to set or replace the DVD-ROM as necessary based on the content identification data received together with the reading position instruction data. The user performs English pronunciation according to the guidance displayed on the display 15 and the sound generated from the speaker 16 while setting or replacing the DVD-ROM according to the instruction displayed on the display 15 under the control of the terminal device 11. The voice of the user so pronounced is collected by the microphone 13 and output to the terminal device 11 as sound data.

  The terminal device 11 transmits sound data indicating the user's voice received from the microphone 13 (hereinafter referred to as “user voice data”) to the server device 20. At that time, the terminal device 11 transmits a combination of content identification data and partial data ID corresponding to the user's pronunciation, that is, data for identifying the partial data reproduced immediately before the user's pronunciation.

  When the server device 20 receives the combination of the user voice data, the content identification data, and the partial data ID, the control unit 201 stores the evaluation reference data corresponding to the received combination of the content identification data and the partial data ID in the evaluation reference data storage. Search is performed from the evaluation criteria DB (see FIG. 12) stored in the unit 205f.

  The input data evaluation unit 206 evaluates the similarity between the received user voice data and the model voice data of the evaluation reference data searched by the control unit 201, and calculates the result as a point indicated by a numerical value of 0 to 100. The input data evaluation unit 206 calculates a deviation value of the newly calculated point using the point distribution data of the searched evaluation reference data, and generates evaluation data indicating the result. Thereafter, the input data evaluation unit 206 updates the point distribution data of the searched evaluation reference data with the calculated points. The server device 20 transmits the calculated evaluation data to the terminal device 11.

  When the terminal device 11 receives the evaluation data, the terminal device 11 performs control such as repetition of reproduction of partial data or transition to reproduction of the next partial data according to the guidance data based on the received evaluation data. As a result, a series of learning programs is provided to the user.

  As described above, the learning system 2 can obtain the same effects as those obtained by the learning system 1. Furthermore, according to the learning system 2, by registering a plurality of content data owned by the user in the server device 20 in advance, the user can use partial data arbitrarily selected from the plurality of content data. You can receive a more varied teaching service.

  Moreover, according to the learning system 2, since the newly transmitted read position instruction data is selected based on the history of the read position instruction data transmitted to the user terminal device 11 in the past, the same partial data is used. The inconvenience that the learning service is repeatedly provided to the same user is avoided.

  Moreover, according to the learning system 2, since each user's pronunciation is evaluated based on the evaluation result with respect to another user's pronunciation, the user can know his / her proficiency more objectively.

  In the learning system 2, since the user voice data is transmitted from the terminal device 11 to the server device 20, the user voice data is compressed in the terminal device 11 so that the smooth provision of the training service is not hindered by the communication time. Then, the user voice data that is transmitted to the server device 20 and compressed by the server device 20 may be decompressed.

  Further, in the learning system 2, since the audio data included in various DVD-ROMs in the server device 20 needs to be stored as the model audio data in the evaluation reference data storage unit 205f, it is desirable that the size is small. . Therefore, the server apparatus 20 may store the model voice data after being compressed, and decompress the compressed model voice data when used for evaluation by the input data evaluation unit 206.
