A method for simultaneously extract the fundamental frequency of a speech signal and segment it

This paper deals with the voiced/unvoiced segmentation of natural speech signals and, inside the voiced intervals of these signals, with the determination of the fundamental frequency f₀. Our primary motivation of developing the method presented in this paper is to obtain precise f₀ information, this both in terms of frequency for relatively fast evolving events, and in terms of time location of these frequential events. The use of a first partial enhancement and of the Analytic Signal extraction techniques allows this. Comparisons with a standard FFT-based method are provided.
