Abstract

Pitch periods in a complex speech signal are determined by evaluating the error in predicting the value of a sample of the signal on the basis of past sample values, and by locating samples for which the prediction error is large. Advantageously, the prediction error signal is devoid of all formant structure, so that there is no chance of confusing pitch signal peaks with formant peaks. A voiced-unvoiced decision is obtained from the ratio of the mean-squared value of the speech signal to the mean-squared value of the prediction error signal.
