摘要
The invention relates to a voice processing system capable of varying the speed of output of digitized audio data stored therein. The digitized audio data is stored using blocks of LPC coefficients. Each block is sufficient to allow twenty milliseconds of speech to be generated therefrom. Periodically, or selectably, the utilization of particular blocks is repeated resulting in a decrease in the speed of output of the speech synthesized therefrom. Alternatively, selectably blocks of LPC coefficients are omitted from use thereby producing a corresponding increase in speech output.
