Synthetic, Multi-Layer, Self-Oscillating Vocal Fold Model Fabrication

Self-oscillating, multi-layer numerical and artificial vocal fold models with thin epithelial and loose cover layers

Identification of geometric parameters influencing the flow-induced vibration of a two-layer self-oscillating computational vocal fold model.

Simplified models have been used to simulate and study the flow-induced vibrations of the human vocal folds. While it is clear that the models' responses are sensitive to geometry, it is not clear how and to what extent specific geometric features influence model motion. In this study geometric features that played significant roles in governing the motion of a two-layer (body-cover), two-dimen...

Simulation of vocal fold oscillation behaviour by a self-oscillating glottis model

As a good compromise between simplicity and approximation of real human vocal vold oscillation behaviour the Ishizaka-Flanagan two-mass model [I] is widely used in articulatory speech synthesis. But its poor results in modelling the oscillatory behaviour during glottal abduction/adduction and in modelling leakage flow during normal phonation are drawbacks. The two-mass model can be improved wit...

A Fast Robust 1D Flow Model for a Self-Oscillating Coupled 2D FEM Vocal Fold Simulation

A balance between the simplicity and speed of lumped-element vocal fold models and the completeness and complexity of continuum-models is required to achieve fast high-quality articulatory speech synthesis. We develop and implement a novel self-oscillating vocal-fold model, composed of a 1D unsteady fluid model loosely coupled with a 2D FEM structural model. The flow model is capable of robustl...

In vivo vocal fold cover layer replacement.

OBJECTIVES/HYPOTHESIS An animal vocal fold replacement model is needed to investigate treatments for vocal fold scarring. We developed a rabbit surgical model, hypothesizing that orthotopic vocal fold cover implants would attach and survive. We further hypothesized that superficial scarring would be limited, allowing unimpeded vibration. STUDY DESIGN Translational research: animal surgical st...
