The perceptual segregation of simultaneous vowels with harmonic, shifted, or random components.
This experiment was an investigation of the ability of listeners to identify the constituents of double vowels (pairs of synthetic vowels, presented concurrently and binaurally). Three variables were manipulated: (1) the size of the difference in F0 between the constituents (0, 1/2, and 6 semitones); (2) the frequency relations among the sinusoids making up the constituents: harmonic, shifted (...
متن کاملPerceptual segregation and pitch shifts of mistuned components in harmonic complexes and in regular inharmonic complexes.
It is unclear whether the perceptual segregation of a mistuned harmonic from a periodic complex tone depends specifically on harmonic relations between the other components. A procedure used previously for harmonic complexes [W. M. Hartmann et al., J. Acoust. Soc. Am. 88, 1712-1724 (1990)] was adapted and extended to regular inharmonic complexes. On each trial, subjects heard a 12-component com...
متن کاملModelling the perceptual segregation of double vowels with a network of neural oscillators
The ability of listeners to identify two simultaneously presented vowels can be improved by introducing a difference in fundamental frequency (F0) between the vowels. We propose an explanation for this phenomenon in the form of a computational model of concurrent sound segregation, which is motivated by neurophysiological evidence of oscillatory firing activity in the auditory cortex and thalam...
متن کاملThe perceptual segregation of simultaneous auditory signals: pulse train segregation and vowel segregation.
In the experiments reported here, we attempted to find out more about how the auditory system is able to separate two simultaneous harmonic sounds. Previous research (Halikia & Bregman, 1984a, 1984b; Scheffers, 1983a) had indicated that a difference in fundamental frequency (F0) between two simultaneous vowel sounds improves their separate identification. In the present experiments, we looked a...
متن کاملModeling the perception of frequency-shifted vowels
A significant fact about speech perception is that intelligibility is preserved when the spectrum is shifted up or down along the frequency scale, across a fairly wide range. To study the relationship between fundamental frequency (F0) and spectrum envelope shifts in vowel perception, we used a high-quality vocoder (STRAIGHT) to process a set of vowels spoken by 3 adult males in /hVd/ context. ...
