Parameterized VT area function inversion
The purpose of our study is to contribute tools for inversion of articulatory to acoustics relations, in specific to perform an estimate of vocal tract area-function parameters from formant frequencies. The inversion is performed in two steps. A first approximation is attained from either a codebook or a neural net and a final optimization is performed by an iterative interpolation for finding ...
متن کاملArticulatory synthesis of formant targeted sounds with parameters derived from the inverse solution of speech production
A new approach to produce high fidelity speech sounds by applying both the inverse solution of speech production and the pitchsynchronousarticulatory synthesis technique is presented. Given a formant trace target, the dynamic vocal-tract area function together with time variant VT length are estimated using an inverse solution of speech production. The improved Kelly-Lochbaum filter of the synt...
متن کاملA method to determine the area function of speech based on perturbation theory
A new method to determine the vocal tract area function of speech from given measured formants based on a new perturbation algorithm is proposed. Two models of VT area function with parameters that have direct relation to formant frequencies are used. A new perturbation algorithm with emphasis on arbitrary area changes and an automatic procedure is proposed. A corresponding computer program is ...
متن کاملVowel acoustic space development in children: a synthesis of acoustic and anatomic data.
PURPOSE This article integrates published acoustic data on the development of vowel production. Age specific data on formant frequencies are considered in the light of information on the development of the vocal tract (VT) to create an anatomic-acoustic description of the maturation of the vowel acoustic space for English. METHOD Literature searches identified 14 studies reporting data on vow...
متن کاملParametric 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...
