Driving a self-oscillating vocal fold model with laryngeal muscle activations

Abstract

A self-oscillating model of the vocal folds (with arbitrary numbers of masses in the length, thickness, and depth dimensions) is driven by inputs that closely resemble muscle activations. With this model, EMG recordings and lung pressures can be used to simulate speech. In the present version, adduction-abduction and vocal fold tensing are probed to demonstrate the dynamics of laryngeal posturing and the corresponding phonation regimes.
