PURPOSE:To reduce connection distortion at a voice unit connection part in a voiced part and to generate a synthetic tone with high quality by generating a pitch pattern, and generating the synthetic tone based on a voice unit and the pitch pattern. CONSTITUTION:Text input (a) inputted from a prescribed input device is analyzed (c) at a text analysis part 3 setting a prescribed dictionary (b) as reference, and a word, the boundary of clauses, and a fundamental accent are detected (d). The detection results of the word. the boundary of the clauses, and the fundamental accent are processed according to a prescribed phonemic rule (e) at a voice synthesis rule part 4, and synthetic waveform data (i) representing a voice reading the text input in an unintonated state is generated. Furthermore, the detection results of the word, the boundary of the clauses, and the fundamental accent are processed according to a prescribed rhythmic rule (j) at the voice synthesis rule part 4, and the pitch pattern (m) representing the rhythm of the whole text input is generated. The pitch pattern is outputted to a voice synthesis part 5 with the synthetic waveform data, and the synthetic tone can be generated based on the pitch pattern and the data. |
