VC transitions have often been found to be better cues for the identification of deleted consonants than CV transitions. The lower score for CV transitions could very well be due to an interfering "click sensation" caused by the abrupt begining of these transitions. In the present investigation the abrubt onset was eliminated by replacing the deleted(More)
A Letter in this Journal [Ohde, R. N. and Sharf, D. J., J. Acoust. Soc. Am. 69, 297-300 (1981)] deals with the identification of voiced and voiceless stops from vocalic transition + vowel stimuli edited from CV and VC syllables. The segmentation points were smoothed by applying a time window. With respect to an earlier study, in which straightforward(More)
An objective analysis has been performed on all 15 Dutch vowels pronounced in /hVt/ words by nine native Dutch, nine non-native, and six deaf males. Spectral representations of the vowel segments were created by determining the mean output levels of a bank of 16 filters (90-7200 Hz), with 1/3-oct bandwidths and logarithmic spacing of their center(More)
Speaking rate in general, and vowel duration more specifically, is thought to affect the dynamic structure of vowel formant tracks. To test this, a single, professional speaker read a long text at two different speaking rates, fast and normal. The present project investigated the extent to which the first and second formant tracks of eight Dutch vowels(More)
Earlier identification experiments with sweep tones are repeated with rising and falling single formant (band) sweeps, with durations ranging from 15 to 40 msec and sweep rates from 0 to 40 oct/sec. Steady-state portions of 100-msec duration are then added to the sweeps. The general conclusions are that the tendency to perceive level and slightly rising(More)
