Description

  The present invention relates to a language learning system that downloads audio content for language learning to a mobile network terminal via the Internet and reproduces it.

In recent years, language learning systems using the Internet are being used. In addition, with the spread of mobile phones that can be connected to the Internet, for example, audio content for language learning is downloaded to a mobile phone, such as that described in Patent Document 1, and the user of the mobile phone plays it back. Language learning systems like this have been proposed.
JP 2003-255811 A

  In such a language learning system, a mobile phone user inputs the URL of the language learning system server by key operation. The server transmits language learning content to the mobile phone. This content is, for example, an HTML document, and includes a phrase in a foreign language example sentence, a description of the phrase, and a link anchor to audio content for learning the pronunciation of the phrase. This content is displayed on the screen of the mobile phone. The mobile phone user learns foreign languages by reading the content of the learning content displayed on the screen, downloading the audio content linked to it, and confirming the pronunciation of the phrase. .

  As described above, in a conventional language learning system, a learning phrase and its description are displayed on the screen of a mobile network terminal such as a mobile phone. Many mobile network terminal screens have a small display area of 240 x 320 pixels or less, and in order to read phrases and explanations, it is necessary to scroll the text information on the screen as needed by key operations on the mobile phone. It was.

  In language learning using a mobile network terminal, it is considered effective to refer to the text of a phrase and its explanation when listening to the sound of the phrase. However, it is difficult to refer to phrases and their descriptions at once on a narrow screen of a mobile network terminal. In particular, when a mobile phone is used as a mobile network terminal, the screen cannot be viewed while listening to sound unless headphones are connected. Furthermore, since the URL of the content is input by a key operation of the mobile network terminal, it is necessary to perform a complicated operation until the content is displayed and the sound is reproduced. For these reasons, it can be said that the conventional language learning system is somewhat difficult from the viewpoint of learning efficiency.

  In order to solve the above problem, in the language learning system of the present invention, the mobile network terminal has a two-dimensional barcode reading function, and the mobile network terminal is printed on a book for language learning. After reading the code and accessing the web server resource corresponding to the URL indicated by the two-dimensional barcode, the audio content is acquired from the content server that provides the audio content for language learning.

  Thus, in the structure of this invention, the text of the phrase which is the object of learning, and its description use what was printed on the book. Therefore, it is possible to hear the sound of the phrase while referring to the text of the phrase and the description thereof. Further, by reading the two-dimensional bar code, it is possible to acquire language learning content without performing complicated key operations. Therefore, according to the configuration of the present invention, language learning can be performed efficiently.

  Further, when the two-dimensional barcode is provided for each phrase printed on the book, acquisition / reproduction of audio content can be started with fewer procedures after the barcode is read.

  The content server includes a unique information acquisition unit that reads unique information of the mobile network terminal, and a unique information database that stores unique information of the registered mobile network terminal, and accesses the content server. The audio content may be acquired only when the unique information matches the information stored in the unique information database. Further, if the specific information of the mobile network terminal accessing the content server does not match that stored in the specific information database, an alternative HTML document that does not include a link anchor to the audio content is transmitted to the mobile network terminal. It is good also as a structure.

  With such a configuration, the audio content is transmitted only to the mobile network terminal owned by the registered user.

  The resource corresponding to the URL indicated by the two-dimensional barcode is a first HTML document managed by the web server, and the first HTML document includes a link to the second HTML document managed by the content server. A plurality of anchors are included, the second HTML document includes a plurality of link anchors to a third HTML document managed by the content server, and the third HTML document includes a link to the audio content. It is good also as a structure in which the link anchor is included.

  In such a configuration, it is possible to separately provide a web server that functions as a kind of portal and a content server that actually provides audio content.

  Further, the content server includes model information acquisition means for reading the model information of the mobile network terminal, and model determination means for determining from the model information whether the mobile network terminal is compatible with playback of the audio content. The audio content may be transmitted to the mobile network terminal only when the mobile network terminal is compatible with the playback of the audio content.

  As described above, according to the present invention, a language learning system capable of efficient learning is provided.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an overall view of a learning system in the first embodiment of the present invention. In this system, the first server 201, the second server 202, the mobile phone base station 301, and the mobile phone base station 301 connected to the Internet I and wirelessly transmit and receive voice information and packet data. Has a mobile phone 302.

  Both the first server 201 and the second server 202 are so-called WWW (World Wide Web) servers capable of transmitting and receiving various data based on HTTP (HyperText Transport Protocol).

  Here, when a packet including an HTTP request for a URL corresponding to a resource in the first or second server is transmitted from the mobile phone 302 to the mobile phone base station 301, the mobile phone base station 301 includes the HTTP included in the packet. The request is converted into a packet conforming to the Internet protocol (TCP / IP), and the HTTP request is transferred to the Web server indicated by the URL. When receiving the HTTP request, the first or second server transmits an HTTP response (for example, data including a resource corresponding to the URL) to the mobile phone base station 301. The mobile phone base station 301 converts the received HTTP response into a packet for the mobile phone 302 and transmits it to the mobile phone 302. Thus, desired resources (HTML document, image, voice, etc.) corresponding to the URL are provided to the user of the mobile phone 302.

  In FIG. 1, only one mobile phone base station 301 and one mobile phone 302 are shown, but actually, a plurality of mobile phone base stations 301 are connected to the Internet. It is possible to simultaneously transmit / receive different data to / from the plurality of mobile phones 302.
