Pitch and Time-Scale Modification of Speech: A Review of the Literature.

Abstract

This report summarized the literature in the areas of pitch and time-scale modification of speech. Based on the discussions in the literature, the report recommends the following four techniques for further evaluation: (1) the pitch-synchronous overlap-add technique; (2) the sinusoidal analysis/synthesis system of Quatieri and McAulay; (3) the harmonic plus noise model of Laroche, Stylianou, and Moulines; and (4) the time-domain harmonic scaling technique. All four techniques are capable of modifying both the pitch and the time scale of speech signals.
