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, ...
متن کاملTowards 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...
متن کاملMonitoring vocal fold abduction through vocal fold contact area.
A number of commercial devices for measuring the transverse electrical conductance of the thyroid cartilage produce waveforms that can be useful for monitoring movements within the larynx during voice production, especially movements that are closely related to the time-variation of the contact between the vocal folds as they vibrate. This paper compares the various approaches that can be used ...
متن کاملEstimation of Vocal Fold Characteristics using a Parametric Source Model
We describe a new method to estimate vocal cord dynamics using a parametric model of glottis movements in order to assess the health of the vocal cords and detect pathological conditions of the larynx. The underlying model is based on that proposed by the Fujisaki-Ljungqvist, modified by reducing the number of parameters. The choice of a parametric model enabled us to assess the impact of the v...
متن کاملA fluid-structure interaction model of vocal fold oscillation
Since fluid-structure interaction within the finite-element method is state of the art in many engineering fields, this method is used in voice analysis. A quasi two-dimensional model of the vocal folds including the ventricular folds is presented. First results of self-sustained vocal fold oscillation are presented and possibilities as well as limitations are discussed.
