A voice synthesizer that is responsive to sequences of digital input command words to phonetically synthesize human speech. The system includes control circuits that are responsive to the input command words to introduce an articulated silent phoneme into the speech pattern, vary the duration of each phoneme produced, as well as to vary the overall rate and volume of the speech generated. In addition, the design utilizes inflection assignment for individual phonemes and also employs a glottal waveform which is more representative of human glottis action. The invention also incorporates resonant suppression into the vocal tract to simulate the dampening effect due to the opening of the glottis, and provides closer simulation of human energy content at higher frequencies to improve the quality of the speech generated.
