Pitch-synchronous, time-domain operation on digitized waveforms of human speech produces artificial changes in prosodic parameters, especially fundamental frequency and rhythm. Pitch of voiced segments is raised or lowered by an algorithm which truncates or "pads," respectively, each pitch period in the stored vector by an appropriate amount. Durations are altered by reduplicating or deleting pitch periods as necessary. Speech output, though of telephone quality, is more natural and intelligible than most fully synthetic speech. Potential applications are varied and far-reaching. (Author/DO)
