| Abstract(in English) | The goal of the STRAIGHT analysis/synthesis system is to produce high quality synthetic speech which is perceptually indistinguishable from the original recording. In some cases the synthetic speech is highly natural, but in others excessive breathiness is remarkable. The main source of the breathiness seems to origin from lack of optimal control of group delay manipulation, through which phase dispersion for the high frequency region of excitation source pulses is realized. Here we report two psychoacoustic evaluation experiments, which showed individual differences of optimal group delay manipulation, as well as its overall tendencies, and what combination of parameter values mimic better(or worse)the original speech. A tentative method of parameter estimation based on physical measure of original speech is suggested. |
