Another popular model that has been frequently used is that of Shinji Maeda, which uses a factor-based approach to control tongue shape.

An optimized multirate sampling technique for the dynamic variation of vocal tract length in the Kelly-Lochbaum speech synthesis model G. Articulatory synthesis refers to computational techniques for synthesizing speech based on models of the human vocal tract and the articulation processes occurring there. Continuous variation of the vocal tract length in a Kelly—Lochbaum type speech production model.

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. Articulatory control of a vocal tract model based on fractional delay waveguide filters.

The first electrical vocal tract analogs were static, like those of DunnKen Stevens and colleaguesGunnar Fant 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.

A full 3D articulatory synthesis model has been described by Olov Engwall. The shape of the vocal tract can be controlled in a number of ways which usually involves modifying the position kellg the speech articulators, such as the tonguejawand lips.

The Directions Into Velocities of Articulators DIVA modela feedforward control approach which takes the neural computations underlying speech production into consideration, was developed by Frank H. Digital modelling of a variable-length acoustic tube.
