Vowel spectra, vowel spaces, and vowel identification.
Twelve Dutch vowels, each pronounced by 50 male speakers, were analyzed in 18 filter bands comparable in bandwidth with the cat's critical band. By considering the sound levels (in decibels) in these filter bands as dimensions, with a principal-component analysis the 18 dimensions per sound were reduced to four factors which together explain 75% of the total variance. The configuration of the a...
متن کاملComparing Vowel Formant Normalization Methods
Results from a large-scale comparative study of vowel formant normalization methods are presented. Effectiveness of methods was evaluated by their ability to improve the equalization and alignment of speaker vowel spaces over raw Hertz measurements. Vowel-intrinsic methods performed poorly, while vowel-extrinsic, formant-intrinsic methods performed the best overall.
متن کاملVowel-specific effects in concurrent vowel identification
An experiment investigated the effects of amplitude ratio ~235 to 35 dB in 10-dB steps! and fundamental frequency difference ~0%, 3%, 6%, and 12%! on the identification of pairs of concurrent synthetic vowels. Vowels as weak as 225 dB relative to their competitor were easier to identify in the presence of a fundamental frequency difference (DF0). Vowels as weak as 235 dB were not. Identificatio...
متن کاملA study of two-formant models for vowel identification
An experiment has been performed where various two-formant models reported in the literature were assessed as to their ability to predict the formant frequencies obtained in a vowel identification task. An alternative model is proposed in which the auditory processing of vowel sounds is assumed to take place in two stages: a peripheral processing stage and a central processing stage. In the per...

Vowels as weak as -25 dB relative to their competitor were easier to identify in the presence of a fundamental frequency difference (delta F0). Vowels as weak as -35 dB were not. Identifi...
