Method of generating an excitation signal for a channel or linear prediction vocoder, and excitation signal generator therefor

摘要

1. Process for the generation of an excitation signal for a speech synthesizer provided with channels or linear prediction, from a signal formed by a predetermined pseudo random sequence of pulses, characterized in that the said sequence is reintialized when a specified event occurs, the frequency of repetition of which event is linked to the fundamental frequency of the speech signal, the amplitude of the excitation signal having a predetermined fixed value and the polarity of the said excitation signal being determined by the logic level of the pulses of the pseudo-random sequence.
