Estimation of Persian Pitch Frequency Using Autocorrelation and Cepstrum Algorithms

the study of the characteristics of a speech has become an important aspect of the speech processing. In recent years researches in analysis, processing and recognition in speech signals are raised. In this paper the methods of finding the fundamental frequency of a speech are examined. Then the methods of Autocorrelation and Cepstrum examined and simulated using Matlab.
