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 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...

An experiment investigated the effects of amplitude ratio (-35 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 -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...
متن کاملFrequency warped modeling of vowel spectra: Dependence on vowel quality
The compact representation of harmonic amplitudes in the sinusoidal coding of speech is an important problem in low bit rate speech compression. A widely used method to achieve this is by the all-pole modeling of the spectral envelope. Often a perceptually warped frequency scale is applied in the all-pole modeling to improve perceived accuracy at low model orders. In this work, an attempt is ma...
