Physics-based synthesis of disordered voices

Jorge C. Lucero, Jean Schoentgen, Mara Behlau

The purpose of this work is the development of a synthesizer of disordered voices, i.e., a generator of sounds that mimic the vocal quality of speakers that suffer from a voice disorder or laryngeal pathology. A physics-based modeling strategy is followed for physiological fidelity and a direct relation between the physiology and the perception of vocal quality. The synthesizer is based on a smooth and asymmetric version of a lumped mucosal wave model of the vocal folds, coupled to a wave-reflexion analog of the vocal tract. In this paper, we report our progress and present results of synthetic voices with various levels of vocal frequency jitter, additive pulsatile noise at the glottis due to airflow turbulence, and tension imbalance between the left and right vocal folds.
