PURPOSE:To obtain a synthesized voice of good phonemic property by obtaining a voice waveform in an interpolating section between respective syllables at the time of converting a character string to a voice by reverse FFT operation after additive average between the spectrum in the end part of a preceding syllable and that in the start part of a succeeding syllable. CONSTITUTION:When a character is inputted, a voice waveform generating part 3 reads out the spectrum of a voice element piece corresponding to the character, and a spectrum interpolation calculating part 2 takes additive average between the spectrum in the end part of a preceding syllable and the read spectrum to generate an interpolating section spectrum, and a voice waveform is generated in the voice waveform generating part 3 by a reverse FFT. Thus, the spectrum of the synthesized voice satisfactorily coincides with that of a natural voice, and the synthesized voice of good phonemic property is obtained. |
