EEE 14. WebbThe PSOLA (Pitch Synchronous OverLap-Add) method [Moulines and Charpentier, 1990] was designed mainly for the modification of speech signals. For time-scalemodifications, the method is a slight variation of the technique described above, in which the length of the repeated/discarded segments is adjusted... [Pg.450] WebbThen overlap and add them. Apply that fade out and fade in: that just scales down the amplitude to zero, smoothly. I overlap them, and where the samples overlap, I'll sum them, I'll add them together. Hence the name of the method: 'overlap-add'. Here are the waveforms concatenated using overlap-add. Now the join is quite hard to spot. lsl benefits.com

We choose TD-PSOLA over the WORLD [9] vocoder due to its superior naturalness and pitch-shifting [19]. TD-PSOLA works by pitch-tracking the speech to determine locations (pitch epochs) to split the signal into chunks corre-sponding to one period. These chunks can then be repeated

PSOLA (Pitch Synchronous Overlap and Add) is a digital signal processing technique used for speech processing and more specifically speech synthesis. It can be used to modify the pitch and duration of a speech signal. It was invented around 1986.

These short term signals can be altered either in the time domain or spectral domain to obtain multiple synthetic short-term signals.
