摘要：Speech analysis and synthesis invole analysis for sinusoidal components andpitch frequency, and synthesis by first phase-resetting to zero at pitch period all sineoscillater components, whether periodic for voiced speech, or at random period inaccordance with a random code for unvoiced speech. As a result, the synthesized speechsignal has the initial line spectrum spread due to pitch structure for better speechquality. Frequency modulation may also be used.
