In this paper the effect of the transglottal pressure on fundamental frequency of sustained voice is investigated using a two-dimensional flexible channel model of the vocal fold coupled with a one-dimensional unsteady flow model. The clinical measurement concerning this effect by other researchers shows that the mechanism involved in the vocal folds' vibration is different in a lower and a higher pitch range. We examine numerically the condition of mechanical properties of vocal folds which has the consistency with the experimental result. The result shows that there seems to exist a close relationship between the parameter values decided by numerical model and real larynx structure.
