This MATLAB exercise implements a pitch period detector based on detecting and tracking peaks in the (real) cepstrum during regions of voiced speech. The major feature of this pitch period detector is the use of a secondary cepstral peak detector, for each frame of speech, in order to detect and correct pitch period detection errors due to effects such as pitch period doubling or halving and related phenomena.
