3D-FE model of the larynx including the vocal folds, arytenoid, thyroid and cricoid cartilages was developed. The vocal fold tissue is modeled as a three layered material representing the epithelium vocal ligament and muscle. First, the frequency modal analysis of the model was performed for nonlinear material characteristics and increasing pre-stress of the vocal folds. Then the results of numerical simulation of the vocal folds oscillations excited by a prescribed aerodynamic pressure loading the surface of the tissue is presented. The FE contact elements are used for modeling the vocal folds collisions.
