Optimum Window Duration

Started by Huzefa March 5, 2006
Hi all
we are doing a voice verification project in MATLAB. I have done a
pitch detection algorithm which is working ok ok depending on the
length of the input as well the length of  hamming window.
Now for male input, the results are quite good if the window duration
is 120-150 samples (sampling rate is 8 KHz) whereas for female voice i
have to reduce window length to almost half if the voice input is very
short (less than a second).
pls suggest the optimum window length and the type of window to be used
(if there is any) and will the results improve if i take larger
duration inputs??
