PROBLEM TO BE SOLVED: To make it possible to realize a natural voice back chorus function and training KARAOKE function by diversified natural voices, by determining the data kinds of the voice data required for a central apparatus in accordance with the summarization result of the request frequencies of the music data from users at a terminal device. SOLUTION: The central apparatus 1 and the terminal device 2 are connected via a communication circuit. This terminal device 2 determines the data kinds of the voice data requested to the central apparatus 1 in accordance with the summarization result of the request frequencies of the music data from the users. Namely, a system control section 25 in the terminal device 2 registers the music number inputted from a remote controller 21 by the user as a request music number in a request frequency management table at every request day. The request frequencies of the users by each of respective pieces of the music are summarized in accordance with the request frequency management table. In such a case, the request frequencies are compressed by a high-grade encoding algorithm and the data kinds of the natural voice data of a high sample rate are allocated to, for example, the number of request times of >=51. |
