This paper has 33 citations. Rosen built a dynamic vocal tract DAVOwhich Dennis later attempted to control by computer. Recent progress in speech production imaging, articulatory control modeling, and tongue biomechanics modeling has led to changes in the way articulatory synthesis is performed . HowardDamian T. The first software articulatory synthesizer regularly used for laboratory experiments was developed at Haskins Laboratories in the mids by Philip RubinTom Baer, and Paul Mermelstein.
Biomechanical modeling of articulators such as the tongue has been pioneered by a number of scientists, including Reiner Wilhelms-Tricarico Yohan Payan  and Jean-Michel Gerard Jianwu Dang and Kiyoshi Honda .
The Directions Into Velocities of Articulators DIVA modela feedforward control approach which takes the neural computations underlying speech production kellly consideration, was developed by Frank H.

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

Kelly and Lochbaum method
From Wikipedia, the free encyclopedia. A full 3D articulatory synthesis model has been described by Olov Engwall. Guenther at Boston University. From This Paper Figures, tables, and topics from this paper. Another popular model that has been frequently used is that of Shinji Maeda, which uses a factor-based approach to control tongue shape. Speech and Audio Processing Articulatory synhhesis refers to computational techniques for synthesizing speech based on models of the human vocal tract and the articulation processes occurring there.
An optimized multirate sampling technique for the dynamic variation of vocal tract length in the Kelly-Lochbaum speech synthesis model G. Kelly and Lochbaum made the first computer simulation; later digital computer simulations have been made, e.

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. One of the few commercial articulatory speech synthesis systems is the NeXT -based system originally developed and marketed by Trillium Sound Research, a spin-off company of the University of Calgarywhere much of the original research was conducted.
