A history 604 is a pointer for specifying a position on the map information, and is a value used in the route search together with the current position passed from the position information acquisition unit 203.

  FIG. 7 is a flowchart showing an outline of processing in the audio reproduction program 202. If the user activates the audio playback program 202 on the mobile phone 101, the position information acquisition unit 203 acquires the current position information by GPS (step 701). The position information acquisition unit 203 transmits the acquired position information to the voice server 104 (step 702). Since voice data and introduction information are returned from the voice server 104, the voice data playback unit 204 plays back the received voice data and transmits the information to the user 201 (steps 703 and 704). When the received data includes the introduction information, the destination display selection unit 205 displays a plurality of destination candidates on the screen of the mobile phone 101 (step 706). When the user 201 selects one of the options, the destination display selection unit 205 transmits the destination change information to the voice server 104 (step 708). The destination change information is reflected in the user information 211, and the corresponding audio data is downloaded from the next time.

  FIG. 8 is a flowchart showing an outline of processing in the audio distribution program 206. In the audio distribution program 206, first, the position information transmitted from the audio reproduction program is acquired (step 801). When the destination is set, the route guidance information is usually provided. The voice data distribution unit 207 acquires the destination 303 of the user 201 from the user information 211 and further acquires the history 603 of the destination 303 from the location information 214 (steps 802 and 803). A route search process is performed, and voice data for performing route guidance from the current position to the destination is acquired from the voice information 210 (step 804). The audio data is transmitted to the mobile phone 101 and reproduced by the audio data reproducing unit (step 805). If no destination is set, referral information will be provided. Moreover, even if it has been set, introduction information may be provided periodically. In that case, the introduction place extraction process shown in FIG. 9 is first executed, and several candidate places to be provided as introduction information are acquired (step 806). Next, the voice data distribution unit 207 acquires the voice data for introduction from the voice information 210 and transmits it to the mobile phone 101 together with the introduction information (steps 807 and 808). The audio data is reproduced by the audio data reproducing unit 204, and the introduction information is displayed on the screen by the destination display selecting unit 205.

  FIG. 9 is a flowchart showing an overview of the introduction location extraction process in the audio distribution program 206. In this process, first, user information is acquired from the preference information 213, and a location that matches the user's preference classification is acquired from the location information 214 as a candidate site (steps 901 and 902). Next, a place where another user having the same preference classification as the user has visited in the past is acquired as a candidate site from the preference information 213 and the visit history 212 (step 903). From these candidate locations, locations that the user has visited in the past are excluded based on the visit history 212 (steps 904 and 905). Finally, several candidate sites that are close to the current location of the user are extracted from the remaining candidate sites (step 906). At this time, if a plurality of preference classifications are included in the candidate site, they are extracted as uniformly as possible. In step 902 and step 903, a match search is normally performed using the minor category 404 of the preference information 213. If the search result is too small, a sufficient amount can be obtained by performing a search again using the major category 403. Can extract candidate sites.
