Introduction:

Voice Warping is speeding up or slowing down of speech signal. It is fairly easier to implement if we were to do this without the constraint of the variation of the pitch. However, in this project we have, earnestly tried implement voice warping, without altering its pitch, using the TD-PSOLA (Time Domain - Pitch Synchronous Overlap and Add) method. In the following sections we have shown the working and implementation of the warping algorithm.
