OBJECTIVES: The vibration of the vocal folds produces the primary sound for the human speech. The vibration depends mainly on the pressure, airflow of the lungs, and the material properties of the vocal folds. In order to change them, muscles in the larynx stretch the vocal folds. This interplay is rarely investigated, but can give insight in the complex process of speech production. Most material properties studies are damaging the tissue; therefore, a nondestructive one is desired. METHODS: An ex vivo phonation experiment combined with the dynamic Pipette Aspiration Technique is used to investigate 10 porcine larynges, under manipulations of different adduction and elongation levels...
