Reason :
-
As we decrease the overlap, we find that the number
of windows increases. As we find the optimum shift for each window, the
total optimum shift for the entire speech signal, increases.
The number of samples to be considered to determine
the optimum shift for each window also, varies from window to window.
The discontinuties in the warped speech, is due to
the mismatch.
