On instantaneous vocal tract length estimation from formant frequencies
The length of the vocal tract and its relationship with formant frequencies is examined at fine temporal scales with the goal of providing accurate estimates of vocal tract length from acoustics on a spectrum-by-spectrum basis despite unknown articulatory information. Accurate vocal tract length estimation is motivated by applications to speaker normalization and biometrics. Analyses presented ...
متن کاملVocal-tract area-function parameters from formant frequencies
The basic three-pararneter vocal tract area function model of Fant [2] has been extended to allow for asymmetry and variable length of the tongue hump section as well as variations of the VT overalllength. An important class of articulations are those that conform with this model, mostly vowel sounds and consonants wi~hout . apical . modification or a secondary posterior art1culatton. Starmg ou...
متن کاملDetermination of the vocal-tract shape from measured formant frequencies.
We model the vocal tract as a lossless acoustic tube and consider the relationship between the resonant frequencies and the cross-sectional area function. Empirical results show that if the logarithm of the area function is band limited preserving only 2n Fourier components, the lowest n pole and n zero frequencies of the admittance function measured at the lips uniquely determine the area coef...
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 کاملVocal Tract Normalization Based on Formant Positions
This paper presents our initial results in a new approach to vocal tract normalization (VTN). In experiments based on continuous automatic speech recognition (ASR) the VTN procedure is in general carried out in both training and test phase. In the training phase it is used to obtain speaker independent acoustic models of phones. In the test phase it is used to convert input observations into ob...
