  Purpose: The present study examined the effects of Delayed Auditory Feedback (DAF) as a rate control intervention for dysarthric speakers with Parkinson's disease. Adverse reactions to relatively long delay intervals are often observed during clinical use of DAF, and may result from improper "matching" of the delayed signal. To facilitate optimal use of DAF, clinicians may need to provide instruction, modeling, and feedback. Therefore, the primary purpose of this study was to evaluate the impact of clinician instruction on the effectiveness of DAF in treating speech deficits. A related purpose was to compare the effects of different delay intervals on speech behaviors. Method: Three males with Parkinson's disease and an associated dysarthria served as participants in this singlesubject study. The A phases consisted of a sen.. View More»
