Improved pulsed residual excited linear prediction:A new excitation for CELP based speech coders
A.W. Black, Ahmet M. KONDOZ, B.G. Evans · Electronics Letters · 1996
The authors present a new secondary pulse excitation for linear prediction based analysis by synthesis speech coders. The structure of the excitation has been specifically designed to model characteristics in the speech waveform which the LTP memory fails to adequately represent. This is achieved using an excitation vector simply consisting of two pulses.
