Modeling the biomechanical influence of epilaryngeal stricture on the vocal folds: a low-dimensional model of vocal-ventricular fold coupling.

PURPOSE Physiological and phonetic studies suggest that, at moderate levels of epilaryngeal stricture, the ventricular folds impinge upon the vocal folds and influence their dynamical behavior, which is thought to be responsible for constricted laryngeal sounds. In this work, the authors examine this hypothesis through biomechanical modeling. METHOD The dynamical response of a low-dimensional, ...

A three-dimensional model of vocal fold abduction/adduction.

A three-dimensional biomechanical model of tissue deformation was developed to simulate dynamic vocal fold abduction and adduction. The model was made of 1721 nearly incompressible finite elements. The cricoarytenoid joint was modeled as a rocking-sliding motion, similar to two concentric cylinders. The vocal ligament and the thyroarytenoid muscle's fiber characteristics were implemented as a f...

High-pitched voice simulation using a two-dimensional vocal fold model

Voiced sounds were simulated with a computer model of the vocal fold composed of a single mass vibrating both parallel and perpendicular to the airflow. The major improvement of the present model over the twomass model is that it has a wider continuous frequency range where self-excitation is possible both below and above the first formant frequency of the vocal tract. The two-dimensional model...

Laryngeal muscular control of vocal fold posturing: Numerical modeling and experimental validation.

A three-dimensional continuum model of vocal fold posturing was developed to investigate laryngeal muscular control of vocal fold geometry, stiffness, and tension, which are difficult to measure in live humans or in vivo models. This model was able to qualitatively reproduce in vivo experimental observations of laryngeal control of vocal fold posturing, despite the many simplifications which ar...

Towards an intermediate water wave model of vocal fold vibration: Evidence from vocal-fold dynamic sonography

A simplified water wave model was developed for predicting the global vibration of human vocal folds. As the depth of the liquids in the lamina propria is 1/2–1/20 of the wavelength, they were analogized to intermediate waters. The water wave model predicted elliptic orbits of the tissue particles with the major axis parallel to the surface, and these ellipses flattened with depth. This vibrati...
