摘要：

A digital high-speed camera system for the endoscopic examination of the larynx allows recording speeds of up to 5,600 frames/s. Recordings of up to 1 s duration can be stored and used for further evaluation. Combined with an image processing program the system is able to render x-t diagrams of vocal cord movement. Data acquired from different locations of each vocal cord can be plotted separately. All of the known objective parameters of the voice can be derived from highspeed glottograms.
