PURPOSE:To obtain a composite voice of a more natural and high quality by constituting the device so that even if a residual waveform of any pitch period of a high-pitched sound, a middle-pitched sound and a low-pitched sound is used to a voice element piece selected in order to synthesize a voice, waveform data of all residual signals that can be selected is extracted by a reverse filter in which 2 voice parameter itself provided to actual synthesis is a coefficient, and a sound source and the parameter are extracted from the same voice in spite of a change of the pitch. CONSTITUTION:A voice parameter of a voice element piece unit of a voice element piece memory is used as a coefficient of a voice analytic filter consisting of a reverse filter of a voice synthesizing filter, waveform data of residual signals of a voice of three kinds of different pitch periods obtained by inputting a voice of pitch periods of a high-pitched sound, a middle-pitched sound and a low-pitched sound to this analytic filter, respectively are extracted, and these waveform data are accumulated in a residual waveform memory. |
