Abstract
Spectra formed from adjacent speech segments are likely to be similar particularly if the pitch is constant. If the pitch is going up, the peaks in the later spectrum will be farther apart; the second peak will be very like a stretched version of the first. An algorithm is given for estimating this stretch and converting it to rate of change of pitch. Results are presented showing the accuracy of the method
