Residual excited linear prediction

Residual excited linear prediction performs LP analysis, but uses the whole residual in res mthesis rather than an impulse. The residual is modified in a manner very similar to that of PSOLA. 

PSOLA, which operates in the time domain. It separates the original speech into frames pitch-synchronously and performs modification ly overlapping and adding these frames onto a new set of epochs, created to match the synthesis specification. Residual-excited linear prediction performs LP analysis, but uses the whole residual in resynthesis rather than an impulse. The residual is modified in a manner very similar to that of PSOLA.
