Speech and Audio Processing An optimized multirate sampling technique for the dynamic variation of vocal tract length in the Kelly-Lochbaum speech synthesis model G. Biomechanical modeling of articulators such as the tongue has been pioneered by a number of scientists, including Reiner Wilhelms-Tricarico [5]Yohan Payan [6] and Jean-Michel Gerard [7]Jianwu Dang and Kiyoshi Honda [8].

A full 3D articulatory synthesos model has been described by Olov Engwall. 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]. Sampled-data representation of a nonuniform lossless tube of continuously variable length. This paper has 33 citations.

Case Study: The Kelly-Lochbaum Digital Speech Synthesis Model

Retrieved lovhbaum ” https: This is implemented by a digital ladder filter that is called the Kelly—Lochbaum model. Speech is created by digitally simulating the flow of air through the representation of the vocal tract. Another popular model that has been frequently used is that of Shinji Maeda, which uses a factor-based approach to control tongue shape.

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.

Articulatory synthesis refers to computational techniques for synthesizing speech based on models of the human vocal tract and the articulation processes occurring there.
