Abstract:
1. A voice synthesizer apparatus comprising: a data acquisition portion that successively obtains phonetic entity data specifying a phonetic entity of a given voice; an envelope acquisition portion that identifies a voice segment corresponding to the phonetic entity specified by the phonetic entity data out of a plurality of voice segments corresponding to different phonetic entities, and that obtains a spectral envelope of a frequency spectrum of the voice segment corresponding to the specified phonetic entity; a spectrum acquisition portion that obtains a frequency spectrum of a plurality of voices which are generated in parallel to one another; an envelope adjustment portion that adjusts a spectral envelope of the frequency spectrum obtained by the spectrum acquisition portion so as to match with the spectral envelope obtained by the envelope acquisition portion; and a voice generation portion that generates an output voice signal from the frequency spectrum having the spectral envelope adjusted by the envelope adjustment portion.
