Chapter 10Frequency-Domain Pitch Estimation

10.1 Introduction

We have seen throughout the text that different approaches to speech analysis/synthesis naturally lead to different methods of pitch and voicing estimation. For example, in homomorphic analysis, the location of quefrency peaks (of lack thereof) in the cepstrum provides a pitch and voicing estimate. Likewise, the distance between primary peaks in the linear prediction error yields an estimate of the pitch period. We also saw that the wavelet transform lends itself to pitch period estimation by way of the correlation of maxima in filter-bank outputs across different scales; this “parallel processing” approach is similar in style to that of an early successful pitch estimation method ...
