Abstract
The phonation process is responsible for generating voiced sounds, an essential and ubiquitous component of speech communication. Although it is long understood that the vocal tract geometry filters the sound to make different vowels, and that the ultimate sound source is attributed to the interaction between the laryngeal airflow and the vocal folds, quantitative studies are necessary for better understanding of the underlying physics of the phonation process and potentially better treatment of voicing pathologies. The goal of this study is to build an effective numerical tool and quantitative analytical tool to study the laryngeal airflow and the fundamental mechanism of sustained vocal fold vibration, in order to complement previous analytical and experimental studies, as well as make improvements to numerical simulation of the phonation process. Using these tools, vocal fold vibration induced by laryngeal airflow is simulated, with which the laryngeal flow dynamics are studied and the underlying physics of sustained vocal fold vibration is explained.
