The Directions Into Velocities of Articulators DIVA modela feedforward control approach which takes the neural computations underlying speech production speexh consideration, was developed by Frank H.
An optimized multirate sampling technique for the dynamic variation of vocal tract length in the Kelly-Lochbaum speech synthesis model G. This page was last edited on 28 Octoberat Digital modelling of a variable-length acoustic tube. Recent progress in speech production imaging, articulatory control modeling, and tongue biomechanics modeling has led to changes in the way articulatory synthesis is performed .

This synthesizer, known as ASY,  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.

Articulatory synthesis – Wikipedia
Articulatory synthesis refers to computational techniques for synthesizing speech based on models of the human vocal tract and the articulation processes occurring there. This paper has 33 citations. One of the few commercial locjbaum 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.
Nordic Acoustical MeetingTampere…. From This Paper Figures, tables, and topics from this paper. Continuous variation of the vocal tract length in a Kelly—Lochbaum type speech production model.
There is a long history of attempts to build mechanical “talking heads. The ArtiSynth project,  headed by Sidney Xynthesis  at the University of British Columbiais a 3D biomechanical modeling toolkit for the human vocal tract and upper airway. Another popular model that has been frequently used is that of Shinji Maeda, which uses a factor-based approach to control tongue shape.
Guenther at Boston University. 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. Speech is created by digitally simulating the flow of air through the representation of the vocal tract.
