You can use the cepstrum. There is a technique called "cepstral peak prominence" that is used to analyze voice quality. The basic idea being that the more periodic (better) voiced quality, the more prominent the cepstral peaks.

I have used the autocorrelation technique and FFt for pitch detection.Is there any other techniques for measuring degree of periodicity in these methods(FFT and autocorrelation)?Do you know any references for cepstral peak prominence by matlab?
