Palate-referenced Articulatory Features for Acoustic-to-Articulator Inversion
In: http://epublications.marquette.edu/cgi/viewcontent.cgi?article%3D1024%26context%3Dspaud_fac
Abstract: The selection of effective articulatory features is an important component of tasks such as acoustic-to-articulator inversion and articulatory synthesis. Although it is common to use direct articulatory sensor measurements as feature variables, this approach. fails to incorporate important physiological information such as palate heigh t and shape and thus is not as representative of vocal tract cross section as desired. We introduce a set of articulator feature variables that are palate referenced and nonnalized with respect to the articulatory working space in order to improve the quality of the vocal tract repr~sentation. These features include nonna lized horizontal positions plus the nornlalized palatal height of two midsagittal and one lateral tongue sensor, as well as normalized lip separation and lip protrusion. The quality of the feature representation is evaluated subjectively by comparing the variances and vowel separation in the working space and quantitatively. through measurement of acoustic-to-articulator inversion error. Resu lts indicate that the palate-referenced features have reduced variance and increased separation between vowels spaces and substantially lower inversion error than direct sensor measures.
