Perceptual naturalness of time-scale modified speech

Abstract (in Japanese) (See Japanese page) 
(in English) Perceptual naturalness of time-scale modified speech is affected by phase relationship between constituent sinusoidal components. A psycho-acoustical experiment was carried out to clarify this effect. Every stimulus consisted of sinusoidal components of which phase relationship was modified from original speech with maintaining the original amplitudes and frequencies. The result suggested that perceptual naturalness kept high for the stimuli of which phase modification was smaller than 1/4π. Based on the result, a possible algorithms is proposed to modify time-scale of speech signal without changing phase relationship between its constituent components.
