On the Use of Autocorrelation Analysis for Pitch Detection

  title={On the Use of Autocorrelation Analysis for Pitch Detection},
  author={R. RABINER},
  • Published 2002
One of the most time honored methods of detecting pitch is to use some type of autocorrelation analysis on speech which has been appropriately preprocessed. The goal of the speech preprocessing in most systems is to whiten, or spectrally flatten, the signal so as to eliminate the effects of the vocal tract spectrum on the detailed shape of the resulting autocorrelation function. The purpose of this paper is to present some results on several types of (nonlinear) preprocessing which can be used… CONTINUE READING
