Write a scilab program to estimate pitch by autocorrelation method using segment size as 50 msec and shift of 10 msec.

Write a scilab program to estimate pitch by cepstrum method using segnment size as 50 msec and shift 10 ms.

Write a scilab program to estimate pitch by SIFT method using segnment size as 50 msec and shift 10 ms.

Consider a male speaker speech speaker signal having pitch period of about 10 ms. Compute its pitch by SIFT method using a segment size of 30 ms, 15 ms and 5 ms. Compare the true autocorrelation sequence and justify their nature. As a result explain how much is the main length of speech segment for the estimation of pitch in term of pitch period T₀.
