Description
Title supplied by cataloger.
Photograph shows a voice experiment apparatus that helps to find the causes of stuttering. Dr. Ray K. Immel, dean of the University of Southern California School of Speech (not pictured), plans to use this device which records air pressure from mouth and nose and movements of tongue, larynx, each lip and so on. Contact apparatus is clamped onto the subject and tubes from it actuate "tambours," which write out the record, each "tambour" marking action of one particular organ. Dr. Immel says that while one sound is being made, muscles already are being brought into play for the next sound. This may give rise to conflicts that cause stuttering. Photograph dated October 30, 1931.
