<p>PROBLEM TO BE SOLVED: To provide a power control that deterioration in the quality of synthesized voices is reduced. SOLUTION: In steps S1 to S4, an amplitude change magnification (r) for the fine pieces of a voiced portion and an amplitude change magnification (s) for the fine pieces of a voiceless portion are obtained based on phoneme average power p0, which is the target of synthesized voices, and power p of selected phoneme pieces. In steps S5 to S11, fine pieces are extracted from the phoneme pieces to be synthesized, the magnification (r)is multiplied to the fine pieces of the voiced portion among the extracted fine pieces and the magnification (s) is multiplied to the fine pieces of the voiceless portion. Then, in a step 12, synthesized voices are obtained using the processed fine pieces.</p> |
