In this paper, we propose a method for analyzing spatial characteristics of the larynx during phonation by high-speed digital imaging. The laryngotopography was applied to the high-speed digital images of normal subjects, and patients with paralysis and cyst. The results show various modes of vibration of the vocal folds particular to the patients with paralysis and cyst and usefulness of the laryngotopograph for clinical purposes.
