Abstract

A voice synthesizer of the type set forth in U.S. Pat. No. 3,836,717 wherein the control signals applied to the devices in the vocal track model take the form of variable pulse width "duty cycle" waveforms. A novel system for producing the duty cycle signals is disclosed. Variable speech rate is provided.
