Parametric model of VT area functions: vowels and consonants
This is an extension of earlier work on vocal tract area function modelling (Fant, 1960, 1992, 1993; Lin, 1990) retaining a minimum of three independent control parameters in a more complex, physiologically oriented model providing a flexible choice of detail structure. Systematic perturbation analysis of vocal tract boundary conditions and of values of the independent control parameters have b...
متن کاملVocal Tract Warping for Normalizing Inter-Speaker Differences in Vocal Tract Transfer Functions
Vocal tract warping functions for normalizing vocal tract transfer functions of seven male subjects were calculated based on a vocal tract deformation method based on the vocal tract length sensitivity function. Vocal tract area functions for the five Japanese vowels of six subjects were tuned for their first four formant frequencies to be close to those of a target subject. The vocal tract war...
متن کاملVisualisation of the vocal tract based on estimation of vocal area functions and formant frequencies
A system for visualisation of the vocal-tract shapes during vowel articulation has been designed and developed. The system generates the vocal tract configuration using a new approach based on extracting both the area functions and the formant frequencies form the acoustic speech signal. Using a linear prediction analysis, the vocal tract area functions and the first three formants are first es...
متن کاملChanges of vocal tract shape and area function by F0 shift
Articulatory variation due to the production of vowels at five pitch frequency (F0) levels (110 Hz, 123 Hz, 130 Hz, 146 Hz, and 164 Hz) was analyzed by volumetric magnetic resonance imaging (MRI). Three Japanese male subjects produced sustained Japanese vowels /a/ and /i/. Observation of vocal tract area functions extracted from the MRI data revealed that F0 shift in vowel production affects no...
متن کاملRecovering gestures from speech signals: a preliminary study for nasal vowels
For nasal vowels, a gesture as simple as the lowering of the velum produces complex acoustic spectra. However, we still find a relative simplicity in the perceptual space; nasality is perceived easily. In this preliminary study, we use statistic method to recover the gesture of the velum. In order to reduce the extreme variability of nasal vowels, we introduced a simulation based on Maeda’s mod...
