Abstract (in Japanese) (See Japanese page) 
(in English) Investigations on analysis and synthesis of expressive voice, such as ``husky'' and ``hoarse'' voices, which are typically found in emotional speech and singing are presented. Such voice usually has complex excitation structures which are not readily represented by a single number, F0. This article introduces optimization of system parameters and evaluation of our new analysis procedure called XSX (eXcitation Structure eXtractor), designed for such complex excitation signals. Pseudo speech signals are made from complex tones with FM and/or AM depending on the experimental design. They have a spectral slope similar to natural voiced sounds and do not have formant structure. The proposed method, XSX consists of two subsystems; an integrated periodicity detector which extracts simultaneous multiple periodicity candidates and a frequency refinement procedure based on instantaneous frequency of F0 and harmonic components. Firstly, the candidate detector is optimized followed by the optimization of the refinement procedure. Secondly, comparative test with conventional F0 extractors were conducted and revealed that the proposed method outperforms those procedures in terms of accuracy and tracking speed.
