Clinical Trial Summary

The purpose of this research project is to test the effects of exposure of different forms of tactile speech feedback on overt stuttering frequency.

Description:

A new medical grade device (FDA - category exempt) has been newly designed and built at the University of Mississippi within the departments of Communication Sciences & Disorders, Exercise Science, and Computer and Electrical Engineering. The device records either sound waves (via a small standard microphone) or three dimensional accelerometer data from the throat of a stuttering subject. This data is digitally signal processed, and "fed back" to the user in the form of a small vibrating disk/film that can be held between the fingers or mounted on the skin. This feedback data does not require the subject to attend to the incoming signal.
