Abstract:

A hypothesis is advanced that severe spectral distortion can be expected in a channel vocoder driven by unsmoothed pitch pulses during those intervals when the pitch is not constant. A vocoder-synthesizer configuration is proposed that minimizes this effect. The question of the smoothing of the excitation periods is related to our hypothesis. Author
