In the text registration service of the present embodiment, a message stating that the teaching material text is copyright-free is displayed on the teaching material text selection request screen displayed on the terminal device 10 of the user. Therefore, it is possible to prevent troubles related to copyright handling.
Furthermore, in the text registration service of the present embodiment, the text data of the teaching material text input by the user through the teaching material text selection request screen and the translation text input through the translation request screen are written in the native language and learning desired language specified in advance. You will be prompted to enter it again when it is not. Accordingly, it is possible to avoid a situation in which a teaching material sentence or a translated sentence whose content does not match the language condition of the user is presented when another user uses the voice addition service.

(Other embodiments)
This embodiment can be modified in various ways.
1. In the voice addition service processing of the above embodiment, when the user who uses the voice addition service designates his / her native language and the desired language for learning, the stored contents of the designated native language and the “Learning Desired Language” field match. In addition, a record in which the stored contents of the desired language and the “native language” field are identified from the teaching material management database 24a, and the user ID of the “registrant” field of the record is displayed as a registrant presentation screen. It was. On the other hand, in addition to their own native language and desired language, users who use the voice add-on service can collect genres of learning materials (sports, music, movies), grouped as a series, or specific local resentments. Specifying “attributes” such as (standard language, Kansai dialect, British English, Minnesota spoken), etc., and displaying the user ID of a user who has registered teaching material text that satisfies those attributes as a registrant presentation screen It may be. In this modification, in addition to the user ID of the user who uses the text registration service, the native language, and the language desired to be learned, the input of the attribute of the learning material is requested, and the input attribute is stored in the learning material management database 24a. On the other hand, the user who uses the voice addition service is also asked to input the attributes of the native language, the language desired for learning, and the learning material, and the record is specified using these three elements as keys. According to this modification, for example, it is possible to satisfy a demand for learning a conversation frequently appearing in a specific genre and a desire for learning a conversation used in a specific region.

2. In the above embodiment, even if the teaching material text uploaded by the user who uses the text registration service and the translated text include discriminatory terms and obscene language, the content is displayed on the teaching material text presentation screen of the voice addition service. It has been unconditionally disclosed to other users. On the other hand, a mechanism for excluding registration of discrimination terms and obscene language may be incorporated in the learning support server device 20. In this modified example, a registration prohibition word database in which character strings representing registration prohibition terms such as discrimination terms and obscene terms are collected is stored in the hard disk 24. When the text data of the teaching material text and the translation text transmitted from the user terminal device 10 in the text registration service process includes the registration prohibition term in the registration prohibition word database, another teaching material text or translation text Reply with a message prompting for input.

3. In the text registration service of the above embodiment, a message stating that the selected teaching material text is copyright-free is displayed on the teaching material text selection request screen displayed on the terminal device 10 of the user. However, there was no mechanism to crack down on the registration of teaching material text that would infringe copyright. On the other hand, a learning message that declares that the teaching material text that is infringing the copyright is posted on the teaching material document presentation screen can be transmitted from the terminal device 10 to the learning support server device 20, and the learning that has received the notification message is transmitted. The support server device 20 may immediately delete the record of the teaching material text related to the declaration from the teaching material management database 24a. According to this modified example, it is possible to more reliably avoid a situation in which teaching material sentences that are copyright infringements are widely disseminated through the voice addition service.

4).

In the above-described embodiment, since the voice produced by the user is added to the cell as the voice data of the voice quality as it is, the user who does not like to hear his / her own voice without knowing it is used by the sentence registration service or voice Sometimes it was difficult to use additional services. On the other hand, the learning support server device 20 is equipped with a function for converting a voice formant, and the voice data formant transmitted from the user terminal device 10 is converted using the function and then added to the cell. It may be. According to this modification, even users who do not like their voices heard by strangers can use the service with peace of mind.

6). In the speech addition service in the above embodiment, if the user who uses the service does not upload the speech data obtained by pronunciation of the teaching material sentence in his / her native language to the learning support server device 20, I was unable to listen to the audio of the teaching material text. On the other hand, it is also possible to cause each user to purchase points distributed only in this system and listen to the language of the language desired for learning in exchange for payment of the purchased points.

7). Evaluation of accuracy (grammar, spelling) and politeness (literal or colloquial) of teaching material sentences and translations presented from the user who uses the voice addition service of the above embodiment via the teaching material text display screen And the obtained evaluation may be provided to a user who uses the teaching material confirmation service. According to this modification, a user who has registered a teaching material text and its translation using the text registration service can receive an evaluation of the teaching material text and the translated text through the text confirmation service, thereby objectively assessing their language skills. Can be grasped. Further, not only text data but also voice data may be evaluated. Furthermore, in the mode of distributing points mentioned above, special points are given to users who have obtained good evaluations on text data and voice data, or the price paid at the time of purchasing points is cashed back. You may make it do.

8. You may enable it to add the some audio | voice data which each different user pronounced the teaching material sentence in the same language to one cell. According to this modification, the user who uses the sentence confirmation service can hear and compare voices added by different users, so that the foreign language can be further understood. In addition, the user who uses the text registration service has to upload the teaching material text and the text data of the translated text to the learning support server device 20, but only one of them may be uploaded.
