Length N = 160 were taken and N = N+ K rectangular window function in the role of the speech signal, the first center of its cut
Wave, more the speech signal waveform cutting wavefront and after clipping, and that the signal is multiplied after clipping and summed to calculate the delay of 0 <K <160 correlation values , and the correlation value obtained by detecting a voice signal pitch period, using MATLAB to draw graphics.
