<p>PROBLEM TO BE SOLVED: To synthesize singing voices of high quality. SOLUTION: A spectrum model synthesis(SMS), which is an analytical and synthetic process, is conducted about the phoneme or two or more phoneme chains, a database 10 is prepared, and the SMS data of the phoneme or phoneme chains required for synthesis are concatenated and synthesized, to obtain singing voices. Into the database 10, separate segment data are stored by each different pitch, dynamics, and tempo concerning the same phoneme or phoneme chain. A harmonic component adjustment means 22 and a non-harmonic component adjustment means 23 adjust the harmonic components and non-harmonic components of read segment data so as to match them to a target pitch. A duration adjustment means 24 adjusts the length of the phonemes or the phoneme chains with the length matching the target tempo. A segment level adjustment means 25 carries out level adjustment, and then connects individual segments, generates harmonic components corresponding to the desired pitch, and synthesizes high quality singing voices with a non-harmonic components and the harmonic component.</p> |
