PROBLEM TO BE SOLVED: To allow users to edit search conditions without having to watch a screen.SOLUTION: An in-vehicle terminal 40 transmits an utterance received through a voice input unit 44 as a voice signal to a relay server 10 using a near-field wireless communication unit 46. A relay server 10 converts voice data received from the in-vehicle terminal 40 into a character string using a voice recognition unit 12, and inquires an address database 22 of a database server 20 as to whether the character string represents a geographic condition or not using a communication unit 13. If a result of the inquiry by the communication unit 13 indicates that the character string generated by the voice recognition unit 12 is a geographic condition, a search is made through a POI database 23 using the geographic condition and a stored non-geographic condition, and the geographic condition is stored in a search history 15. If the result indicates that the character string is non-geographic condition, a search is made through the POI database 23 using the non-geographic condition and a geographic condition stored in the search history 15, and the non-geographic condition is stored in the search history 15.SELECTED DRAWING: Figure 1 |
