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 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...
متن کاملMeasurement of vowel nasalization by multi - dimensional acoustic analysis
When the velum lowers during vowels, the velopharyngeal port is opened, and there is acoustic coupling between the nasal cavity and the main vocal tract, giving rise to a distinct acoustic quality which we call nasality. Nasal coupling results in energy losses at low frequencies, damping of oral formants (especially F1), and introduction of nasal formants corresponding to the resonances of the ...

متن کاملVowel Duration and Spectra as Perceptual Cues to Vowel Quantity: a Comparison of Japanese and Swedish
A distinction in vowel quantity is typically realized acoustically by vowel duration. Research on the perception of Swedish vowel quantity supports this and further suggests that when the duration of a vowel is relatively long (due, e.g., to inherent duration), vowel quantity may not be adequately cued by duration alone and may also make use of the vowel spectra to distinguish vowel quantities....
