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 کاملA Comparison of Vowel Acoustics Between Older and Younger Adults
Previous research has shown a difference in vowel acoustics between older and younger adults, possibly related to age-related changes in vocal tract morphology. Data suggest that vowel acoustics may vary as a function of neighborhood density and word frequency in older adults, possibly due to the mediating influence of lexical access. However, no studies have examined the relationship of densit...
متن کاملVibrato and vowel identification
The influence of vibrato on vowel identification i s studied in synthesized vowel sounds with fundamental frequencies between 300 and 1000 Hz. Phonetically trained subjects were asked to identify these stimuli presented with and without vibrato a s any of 12 Swedish long vowels. Small and occasional effects a r e observed on the mean formant frequencies and the scatter between the responses. Ho...
