Symmetrical vocal fold oscillations excited by aerodynamic forces resulting from fluid-structure interaction are considered. Animation of the vocal fold vibrations is performed and the Lambert’s emission cosine law is used for computation of radiant light intensity reflected from the visible vocal folds’ surface. The vibrations of the vocal folds are studied for increasing lung pressure at different fundamental frequencies and different prephonatory glottal half-gaps.
