[Detection of phonetically significant nonuniformity by the high frequency slope of the spectrum of a synthetic vowel].
Conditions for perception of phonetically relevant ununiformity at high frequency slope of the spectrum of synthetic noise--excited vowel were studied with the aid of psychoacoustic technique. The threshold for detection of high frequency spectral peak did not depend on the properties of the stimulus spectrum in low frequency region. The detection threshold could be influenced by spectrum properties near the peak location. The data obtained are inconsistent with the hypothesis of identification of spectral peaks with formants being the intermediate procedure in phonetic interpretation of the vowel.
