PROBLEM TO BE SOLVED: To sing a song with a format according to an inputted pitch by making a formant parameter stored in a phoneme data base reflect the change of the formant parameter answering to the change of the pitch. SOLUTION: The phoneme data base 301 is one collecting the formant data at every phoneme, and when a lapse time from an utterance start of its phoneme and the pitch at the time are inputted to the collection 302-1 to N of the formant data of one phoneme, the answering formant parameter is outputted uniquely. Then, the phoneme data base 301 inputs a phoneme number, the pitch and the lapse time from the utterance start of its phoneme specifying the phoneme and outputs the formant parameter according to the input data. Thus, in the case of making sing using a formant synthetic sound source, a more natural synthetic sound is obtained, and a natural singing voice suited to the change of various performance information is synthesized. |
