Fundamental frequency estimation of speech signals using MUSIC algorithm

摘要

In this paper, the estimation method of the pitch frequency of speech signals using the MUSIC algorithm is described. This algorithm is a method of estimating the power spectrum of the signal by using eigenvalues and corresponding eigenvectors of the autocorrelation matrix, and not influenced easily by the noise. It is shown that our method is more effective than the conventional cepstrum method by the experiment.
