Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, the laryngeal movements of ispiratory phonation were
observed using endoscopic high-speed digital imaging. During
inspiratory phonation, the glottal chink at the posterior potion of
the vocal folds was consitently observed. Three different vocal fold
vibratory patterns, such as fry, modal, and falsetto, were observed in
inspiratory phoation as well as in expiratory phonation. Mucosal wave
of inspiratory phonation propagated from the upper lips to the lower
lips, that is the opposite direction to the muscal wave of expiratory
