Laryngeal imaging provides the laryngologist with diagnostic information and the speech pathologist with treatment planning information. The history of laryngeal imaging now spans over 150 years beginning with the work of Manuel Garcia. Since then, the technology of imaging has advanced from simply visual observation to mechanical stroboscopic images to high speed motion pictures of the larynx The purpose of this presentation is to identify factors in voice onset that can be identified from high speed digital imaging. High speed digital imaging has an advantage over videostroboscopy in that real time cycle to cycle vibratory characteristics of the vocal folds can be identified. Voice onset is often thought to be the key to identifying such disorders as spasmodic dysphonia and muscle tension dysphonia. The purpose of this study is to examine rate and symmetry of vocal fold vibration produced in various types of voice onset, namely normal breathy and hard attack.The advantages of high speed video compared to videostroboscopywill be discussed.

Dr. Thomas Murry is Professor of Speech Pathology in Otolaryngology, Department of Otolaryngology, Weill Cornell Medical College. He completed his Ph.D. and post-doctoral research fellowship at the University of Florida. Dr. Murry has distinguished himself as a clinician, scientist, and educator in the areas of voice disorders. His research in voice science encompasses neurolaryngology, outcomes of treatment of singers, performer?s voice disorders, and outcomes of multi-specialty treatments for voice and swallowing problems. Dr. Murry has published over 130 peer-reviewed articles on voice and swallowing in peer-reviewed journals and has presented over 500 lectures at conferences in the United States and t hroughout the world.
