Abstract
A noise-free speech synthesizer is disclosed which interrupts an audible output of synthesized sounds during the period of time where a sound waveform signal is at a relatively low level (amplitude), that is, a voiceless interval, a silent interval or a pitch control interval, wherein a reference level is established for the purpose of controlling pitch. Such low-level cut-off avoids the harsh click of sound cut-off.
