ABSTRACT:
A speech synthesizer is disclosed in which instantaneous conversational speech can be produced by an operator. The speech synthesizer comprises a two dimensional input device, such as a joystick or a playing tablet, for producing vowel-like sounds, a plurality of selection keys for producing consonant-like sounds and a third control for varying the pitch or inflection of the produced signal. The electronic circuit for producing the voicing wave forms can be either analog or digital. The system features simultaneous and continuous control of two formants.
