Perceptual cues for speaker individualities embedded in spectral envelopes of vowels and fundamental frequency (F0) contours of words were investigated through psychoacoustic experiments. First, the frequency bands having speaker individualities are estimated using stimuli created by systematically varying the spectral shape in specific frequency bands. The results suggest that speaker individualities...
Temporal envelope and periodicity cues (TEPC) are crucial for speech perception of hearing-impaired people who have poor frequency selectivity. This paper investigates the contributions of TEPCs extracted from different frequency regions to lexical tone perception of Mandarin. Tone identification tests were carried out with tone-contrasting monosyllabic and disyllabic words. Normal- hearing subjects...
Several phenomena, which were made clear by psycho-acoustic experiments, have not electric physiologic evidence data. The missing fundamental phenomenon is one of the phenomena. We try making clear the mechanism how the missing fundamental is produced. By psycho-acoustic experiments and cochlear models experiments, we investigated its fundamental characteristics in the low frequency range where the...
