Recent progress in speech production imaging, articulatory control modeling, and tongue biomechanics modeling has led to changes in the way articulatory synthesis is performed [1].

Articulatory synthesis

From Wikipedia, the free encyclopedia. This synthesizer, known as ASY, [3] was a computational model of speech production based on vocal tract models developed at Bell Laboratories in the s and s by Paul Mermelstein, Cecil Coker, and colleagues.

The shape of the vocal tract can be controlled in a number of ways which usually involves modifying the position of the speech articulators, such as the tonguejawand lips.

In this paper we propose an extended approach, where the tube sections approximating the profile of the tract are conical instead of cylindrical.
