The voice source for the synthetic speech system is human generated speech waveforms that are inverse filtered to produce glottal waveforms representing larynx sound. These glottal waveforms are modified in pitch and amplitude, as required, to produce the desired sound. The human quality of the synthetically generated voice is further brought out by adding vocal tract effects, as desired. The pitch control is effected in one of two alternate ways, a loop method, or a concatenation method.
