PROBLEM TO BE SOLVED: To output synthesized sound waveforms having superior tone quality by reading optimum unit voice waveforms corresponding to a first phoneme symbol partial string, that is divided by a prescribed priority order, by a reading means and connecting them by a waveform connecting means. SOLUTION: A voice synthesizer 10 includes a microcomputer 12. The microcomputer 12 accepts an input character string consists of text sentence data and a morpheme analysis of the input character string is conducted by a morpheme analysis means 12e employing a text analysis dictionary 14. Then, the input character string is divided to phoneme symbol partial string by a dividing means 12f, converted to a phoneme symbol string in that dividing points are set and pitch and power patterns of the input character string are generated. A waveform connecting means 12g forms up, connects and edits the unit voice waveforms read from a voice waveform database 16 based on the pitch and the power patterns at a waveform reading means 12h and synthesized sound is outputted. |
