Abstract

An uttered speech of a user is acquired and recognized, and the recognition result is output. Evaluation information is generated from the recognition result. The position where the evaluation information is generated is detected. A reliability determining unit determines reliability of the evaluation information using post information posted on the Internet within a predetermined distance range based on the position where the evaluation information is generated within a predetermined period based on current date and time and determines whether the evaluation information is to be transmitted. A communication unit performs transmission, to the travel assistance server, of the evaluation information determined to be transmitted by the reliability determining unit, reception of the evaluation information stored in the travel assistance server, and reception of the post information posted on the Internet. An information providing unit provides the evaluation information received by the communication unit from the travel assistance server.
