In the present invention, an in-vehicle terminal sends a speech input from a speech input unit to a relay server as a speech signal using a short-range wireless communication unit. The relay server converts the speech data received from the in-vehicle terminal at a speech recognizing unit into a string and queries, via a communication unit, an address database of a database server as to whether or not this string is a geographical condition. On the basis of the query result of the communication unit, if the string converted by the speech recognizing unit is a geographical condition, a POI database is searched with the geographical condition and a stored non-geographical condition, and the geographical condition is stored in a search history. If the string is a non-geographical condition, the POI database is searched with the non-geographical condition and the geographical condition stored in the search history, and the non-geographical condition is stored in the search history. |
