ABSTRACT:
A composite pitch pattern of an artificial waveform of a composite sound indicating characters is produced according to a general pitch pattern producing model, and a pitch pattern of a VCV phoneme-chain waveform of each of VCV phoneme-chains corresponding to the characters is produced from an actual voice sample. Each VCV phoneme-chain composed of a preceding vowel, a consonant and a succeeding vowel has a pitch fine structure and a pitch fluctuation. Thereafter, an overall inclination of the pitch pattern of each VCV phoneme-chain waveform is adjusted to that of a portion of the composite pitch pattern corresponding to the-same VCV phoneme-chain to overlap transitional portions of preceding and succeeding vowels in a changed pitch pattern of each VCV phoneme-chain waveform with those in the corresponding portion of the composite pitch pattern. Therefore, when changed pitch patterns of the VCV phoneme-chain waveforms are connected with each other, a synthesized sound of the characters can be obtained while the synthesized sound maintains a pitch fine structure and a pitch fluctuation.
