PURPOSE:To improve the naturalness of a synthesized speech by performing rhythm processing for each phoneme with accent and continuance time on multistages. CONSTITUTION:A host computer 1 generates a multistage accent and a continuance time variation quantity in stages of phoneme train data and respective phonemes as to an input sentence and a rhythm processing part 3 generates a pitch pattern of a multistage accent quantity in >=3 stages as to the phoneme train data, generates an energy pattern in multi-stages of the phoneme train data with the pattern, and finds multistage continuance time by adjusting the continuance period of time of each phoneme in the phoneme train with the continuance time variation quantity; and a synthesis processing part 4 generates the synthesized speech with parameters, etc., of the pitch pattern, energy pattern, and continuance. |
