Description

  The present invention relates to an in-vehicle device, a server, and a point information audio output method, and more particularly, to an in-vehicle device, a server, and a point information audio output method having a function of outputting point information collectively as audio.

  In recent years, there are in-vehicle devices having a communication function for accessing a server on the Internet. Some of these in-vehicle devices have a function of analyzing and displaying XML (eXtensible Markup Language), and content data described in XML can be acquired from a server and displayed. .

Some of the above-described in-vehicle devices are equipped with a function for acquiring point information (Patent Document 1). The point information is information including a place where an event such as a fireworks display or a concert is held. Individual point information is linked to a list called a point list. The in-vehicle device refers to the point list and acquires point information linked to the point list. The point information is associated with a TTS (Text to Speak) file. The TTS file is a file for outputting this as a sound. The driver, for example, executes the “read all cases” function implemented in the in-vehicle device, so that the in-vehicle device acquires the point information of all cases and the TTS file associated therewith from the point list, and reads out each point information. .
JP 2001-273203 A

However, in the above-described prior art, all TTS files can be read only when TTS files exist for all pieces of point information linked to the point list. That is, when there is even one piece of point information for which no TTS file exists, it is impossible to execute the all cases reading function. In the prior art, whether or not a TTS file exists for all point information is determined by actually downloading a TTS file according to a point link. For this reason, when there is point information where no TTS file exists, there is a problem that time spent for downloading other TTS files is wasted.
There is a problem.

  Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide an in-vehicle device, a server, and a point information audio output method capable of minimizing the time required for downloading.

In order to achieve such an object, the present invention is an in-vehicle device having a function of downloading a TTS file for outputting point information by voice from a predetermined server, and acquires a list of the point information from the server. A list acquisition unit, a TTS file acquisition unit that collectively acquires TTS files corresponding to the location information managed in the list from the predetermined server, and the TTS files acquired by the TTS file acquisition unit are sequentially output by voice. All TTS files when the list includes a description indicating the presence / absence of a TTS file for each point information, and the TTS file acquisition means includes a description in which no TTS file exists in the list. Is configured not to perform acquisition. Since it is possible to determine whether or not the TTS file exists without actually downloading the point information or the TTS file, it is possible to delete the time and effort to download the TTS file unnecessarily. It can be minimized.

  Further, the present invention has, for example, an all-cases reading instruction means for instructing to collectively acquire TTS files corresponding to the spot information managed in the list, If the list includes a description in which no TTS file exists, the list may be invalidated. When there is point information that does not have a TTS file, the “read all” function is configured to be disabled so that the user can be prevented from inputting an instruction to download the TTS file. Can be improved.

Further, the present invention is an in-vehicle device having a function of downloading a TTS file for outputting point information by voice from a predetermined server, and a list acquisition means for acquiring a list of the point information from the server; TTS file acquisition means for collectively acquiring TTS files corresponding to the location information managed in the list from the predetermined server, and audio output means for sequentially outputting the TTS files acquired by the TTS file acquisition means. If the list includes a description indicating the presence / absence of a TTS file for each piece of location information, and the TTS file acquisition means includes a description in which no TTS file exists in the list, Get the TTS file
When the location information in the list includes a description in which a TTS file corresponding to the location information exists, the audio output means outputs the TTS file corresponding to the location information as audio and corresponds to the location information. When a description in which no TTS file exists is included, it is configured to output a voice that there is no TTS file corresponding to the point information . The downloaded TTS file can be surely reproduced, and the act of unnecessarily downloading can be prevented. That is, it is possible to minimize the time required for downloading by eliminating useless downloading.

Further, the present invention is a server that manages a list of spot information downloaded to an in-vehicle device and a TTS file for outputting the spot information by voice, and the list indicates whether a TTS file exists for each spot information. A description is shown, and based on the description, whether to execute download to the in- vehicle device is selected in the in- vehicle device .
