We created a voice guide system for historic sites on trial, in which cell phones are applied as the interface to interpret for the history of the site. The system developed here, converts the data with a text into the synthesized voice data, and compresses it. The system stores the compressed voice data in the database. And, the data can be accessible to the database from the cellular phone. Also, we picked out the technical and management problems of the trial system from a questionnaire and studied the effectiveness of the system. In this paper, we describe this system would be useful if the economic problem of downloading data is solved.
