Abstract
A 3D model of the vocal tract to be used for articulatory and visual synthesis has been developed. The tract is modeled as a smoothly varying tube created of a polygon mesh that can be modified by seven articulatory parameters. The model is to be employed firstly for speech synthesis using e.g. direct calculations of the cross-sectional areas in the tract and secondly as a visual aid for pronounciation training, e.g. of hearing-impaired children.
