Date May 22, 1998An apparatus and method that reproduces a voice signal at different rates without a change in pitch. Neighboring voice waveforms having a same length and minimum form differences from an input voice signal are selected and overlapped. An output voice waveform is then generated that is rate converted by replacing a part of the voice waveform of the input voice signal with the overlapped voice waveforms, or, alternatively, by inserting the overlapped voice waveforms into the voice waveform of the input voice signal.
