<b><i>Purpose:</i></b> The aim of this study was to establish a method to observe vocal fold vibration using a low-cost high-speed laryngeal imaging system. <b><i>Procedures:</i></b> We assembled a high-speed imaging system with a consumer digital camera and a rigid laryngeal endoscope. The camera can shoot digital images at a rate of 1,200 frames per second and be purchased for about USD 1,000 in Japan. <b><i>Results:</i></b> We examined the normal and pathological vocal folds of 215 subjects with our new system and analyzed the vocal fold vibration in these subjects by playback of a video and kymograph images. <b><i>Conclusions:</i></b> Our high-speed laryngeal imaging system is highly cost-effective and can be a useful tool for examining the vocal folds of patients with voice disorders.
