ABSTRACT:
A process is described for extracting the most-likely estimate of pitch f a digitized speech signal. For each segment of speech analyzed, a measure of merit is constructed for each of several possible preselected pitch periods. These measures are periodically combined with previous measures of merit to determine a one most-likely choice of pitch period for a previous segment of speech.
