This is an 18 year-old man demonstrating delayed auditory feedback (DAF) using a small, inexpensive pocket sized device. While DAF does not completely eliminate stuttering behaviors, it often reduces both primary and secondary characteristics of the disorder. There may be subpopulations who respond more favorably to DAF. Results are variable with the majority of individuals benefiting at some level from the DAF condition. The individual in this video had developed a longstanding behavior of foot stomping during blocks. Since the initiation of DAF, the stomping behavior has completely stopped and has not returned in subsequent months. His speech has also improved based on patient feedback, listener observations, and quantitative data.
Delayed auditory feedback is an underused tool for the treatment of stuttering. Watch video
