PROBLEM TO BE SOLVED: To perform natural and smooth voice synthesis without enlarging the storage capacity of a phoneme unit waveform storage part so much. SOLUTION: Text data inputted from a text data input part 1 are sent to a phonetic symbol generation part 2 and phonetic symbols are generated there. A phoneme unit waveform calling part 3 calls data pertinent to first phoneme unit waveform data A0 from the phoneme unit waveform storage part 4 based on the generated phonetic symbol. For the text data inputted from the text data input part 1, a phonetic rule is analyzed by a phonetic rule part 6 and a phonetic parameter generation part 7 generates a phonetic parameter based on the analysis. Then, a pitch pattern generation part 8 generates a pitch pattern based on the phonetic parameter. The phoneme waveform data string generation means 12 of a waveform data connection part 5A receives a parameter numerical value from a voice quality parameter storage part 11 based on information from the pitch pattern generation part 8 and generates the phoneme unit waveform data A1 to follow next based on it and the data A0 from the calling part 3. |
