A speech synthesis system uses a programmable digital divider to generate desired formant frequencies. The divide factor is controlled by an MPU. The output of the divider is passed through a sinewave shaper and then through an electronically controlled amplitude amplifier to provide an audio output. The system is based upon the realization that alternating between two formant frequencies at the pitch rate generates a sound comparable to generating two formants simultaneously and adding algebraically. |
