<p>An apparatus is designed for synthesizing a voice signal using a plurality of phonetic piece data each indicating a phonetic piece which contains at least two phoneme sections corresponding to different phonemes. In the apparatus, a phonetic piece adjustor forms a target section from a first phonetic piece and a second phonetic piece so as to connect the first phonetic piece and the second phonetic piece to each other such that the target section is formed of a rear phoneme section of the first phonetic piece and a front phoneme section of the second phonetic piece, and expands the target section by a target time length to form an adjustment section such that a central part of the target section is expanded at an expansion rate higher than that of a front part and a rear part of the target section, to thereby create synthesized phonetic piece data of the adjustment section having the target time length. A voice synthesizer creates a voice signal from the synthesized phonetic piece data created by the phonetic piece adjustment part.</p> |
