Abstract: |
In this case study, a 59-yr-old male with progressive supranuclear palsy and hypokinetic dysarthria wore a small, solid state, battery operated, delayed auditory feedback (DAF) device to reduce speech rate and to aid speech intelligibility. Measures of speech rate, intensity, and overall intelligibility indicate that when the instrument was worn, the S's speech was slower, vocal intensity increased, and intelligibility was markedly improved. The application of DAF to the treatment of communication disorders is discussed. |
