ABSTRACT This paper examines the degrees of correlation among vocal tract and orofacial movement data and the speech acoustics. Multilinear techniques are applied to support the claims that orofacial motion during speech is largely a by-product of producing the speech acoustics and further that the spectral envelope of the speech acoustics is better estimated by the 3D motion of the face than the mid-sagittal motion of the anterior vocal tract (lips, tongue, and jaw).

Unified physiological model of audible-visible speech production
In this paper, vocal tract and orofacial motions are measured during speech production in order to demonstrate that vocal tract motion can be used to estimate its orofacial counterpart. The inversion, i.e. vocal tract behavior estimation from orofacial motion, is also possible, but to a smaller extent. The numerical results showed that vocal tract motion accounted for 96% of the total variance ...
متن کاملFunctional Principal Component Analysis of Vocal Tract Area Functions
This paper shows the application of a functional version of principal component analysis to build a parametrization of vocal tract area functions for vowel production. Sets of measured area values for ten vowels are expressed as smooth functional data and next decomposed into a mean area function and a basis of orthogonal eigenfunctions. Interpretations of the first four eigenfunctions are prov...
متن کاملModeling of a speech production system based on MRI measurement of three-dimensional vocal tract shapes during fricative consonant phonation
This study, based on the measurement of three-dimensional (3-D) vocal tract shapes during fricative consonant phonation, presents a realistic modeling of a human speech production system. The 3-D shapes of a vocal tract and a dental crown were measured using Magnetic Resonance Imaging (MRI). A male subject was asked to produce the fricatives /s/ and /6/ while wearing a dental crown plate that c...
متن کاملDeriving vocal tract shapes from electromagnetic articulograph data via geometric adaptation and matching
In this paper, we present our efforts towards deriving vocal tract shapes from ElectroMagnetic Articulograph data (EMA) via geometric adaptation and matching. We describe a novel approach for adapting Maeda’s geometric model of the vocal tract to one speaker in the MOCHA database. We show how we can rely solely on the EMA data for adaptation. We present our search technique for the vocal tract ...
متن کاملSpeaker individualities of vocal tract shapes of Japanese vowels measured by magnetic resonance images
Three dimensional vocal tract shapes of three males and three females were measured from the magnetic resonance images that were taken during sustained phonation of the five Japanese vowels. Dimensional differences in the vocal tract length of the subjects were quantitatively measured by dividing the entire vocal tract into the oral, the pharyngeal and the laryngeal sections. To investigate mai...
