Claims

[Scope of utility model registration request]

PCM codes corresponding to each of the plurality of channels are input to a reproduction means to reproduce phoneme waveforms for each channel, and the phoneme waveforms of each channel shifted by a pitch period are added by an addition means, and the addition result is used as a synthesized sound. In the speech synthesizer that outputs, the phoneme waveform of each channel is a phoneme waveform having a constant time length from the start of reproduction, and the reproduction means is shared by each channel, and the reproduction processing in each channel is performed within one sample time. What is claimed is: 1. A speech synthesizer which performs the above on a time-division basis, and wherein said adding means accumulates the reproduced phoneme waveforms of each channel within one sample time.
