Influence of Altered Auditory Feedback Device Usage on Stuttering's Impact

Lawrence Molt and J. Scott Yaruss

This study examines the influence of the use of an altered auditory feedback device (AAF) on the perceived impact of stuttering for 15 adult stutterers. The Overall Assessment of the Speaker's Experience with Stuttering (OASES) was administered during initial qualifying testing for AAF usage, and again at 1 month, 3 months, 6 months, and 12 months after participants received the AAF device. Results are discussed in terms of changes in reactions to stuttering, functional communication, and quality of life measures. Relationships between AAF device usage patterns, speech fluency, and OASES scores are examined.
