Analysis of the Generation of the Vocal Fold Vibration

Abstract

In this paper the effect of the configuration of the vocal fold on voice generation is investigated using a two-dimensional flexible channel model of the vocal fold coupled with a one-dimensional unsteady flow model. Especially, we examine the relationship between vocal fold thickness and minimum lung pressure for voice generation. The numerical result shows that there exists an optimal thickness of the vocal fold for ease of phonation since the relationship has a U-shape.
