采用一系列的单受试者实验，评估了频率改变听觉反馈（FAF）对四名口吃成年男性言语表现的影响。使用正负一个倍频程的改变，FAF与正常听觉反馈（NAF）进行了比较，在口头阅读和自发讲话的口吃间隔，无口吃的讲话率，和讲话自然的测量。还评估了两名对FAF有阳性反应的受试者的扩展FAF条件对自发言语的影响。结果显示，受试者对FAF的反应没有差异：一名受试者没有反应，另一名受试者产生了最初的临时反应，第三名受试者表现出言语质量下降，口吃减少最少，第四名受试者表现出言语表现的实质性和持续性改善。这些发现对目前关于口吃和FAF之间关系的研究和理论的一些启示进行了讨论。
A series of single-subject experiments evaluated the effects of frequency-altered auditory feedback (FAF) on the speech performance of four adult males who stutter. Using alterations of plus or minus one octave, FAF was compared with normal auditory feedback (NAF) in oral reading and spontaneous speech with measurements made of stuttered intervals, stutter-free speech rate, and speech naturalness. The effects of extended FAF conditions on spontaneous speech were also evaluated for two subjects who demonstrated a positive response to FAF. Results showed no consistencies across subjects in responses to FAF: One subject showed no response, another produced an initial temporary response, a third showed a deterioration in speech quality with minimal reductions in stuttering, and a fourth displayed substantial and sustained improvements in speech performance. Some implications of these findings for current research and theory about the relationship between stuttering and FAF are discussed.
