Detection of temporal modulation of "size" in vowel sequences

Abstract

Size extraction, Resonance characteristics, Size modulation detection, Timbre perception Experiments were performed with listeners to detect the STSM in a vowel sequence. The measured characteristics appeared to be high-pass. The observed high-pass tendency suggested that a more efficient cue was available based on the differences in fine temporal structures caused by the resonance change within a vowel. This indicated that the current experimental paradigm was not appropriate to measure the limit of tracking speed of the VTL extraction process. Therefore, further study will be required by using stimuli that cannot be judged as STSM on the basis of the fine structural cues.
