ABSTRACT:
A speech synthesizing apparatus for deforming and connecting speech pieces to synthesize speech has a speech waveform database for storing data of an accent type of a speech piece of a word or a syllable uttered with type-0 accent and type-1 accent, data of phonemic transcription of the speech piece and data of a position at which the speech piece can be segmented, an input buffer for storing a character string of phonemic transcription and prosody of speech to be synthesized, a synthesis unit selecting unit for retrieving candidates of speech pieces from the speech waveform database on the basis of the character string of phonemic transcription in the input buffer, and a used speech piece selecting unit for determining a speech piece to be practically used among the retrieved candidates according to an accent type of speech to be synthesized and a position in the speech at which the speech piece is used, thereby preventing degradation of a quality of sound when the speech piece is processed.
