PURPOSE:To synthesize into natural voices even from special voices, such as husky voices and hoarse voices without changing entire band into UV. CONSTITUTION:The powder deviation and peak on the low region side of signal vectors are detected (S21, S22) when the result of judgment (S13) of V(vocal sound)/UV(unvocal sound) of respective bands obtd. by using the pitch obtd. by a pitch search (S11) and amplitude evaluation (S12) on the time base, such as self-correlation, is the entire band UV (S14) in pitch extraction with the voice analyzing synthesis system for executing a frequency analysis. The max. value near this peak is detected (S24) and the pitch P is calculated (S25) in accordance with the respective positions in the peak and max. frequency axes. The V/UV is then judged again (S27). |
