This study investigated the effects of altered auditory feedback on stuttering frequency during speech production at two different speech rates, Nine stutterers, who exhibited at least 5% dysfluency during a reading task, served as subjects. They read eight different passages (each 300 syllables in length) while receiving four conditions of auditory feedback: nonaltered, masking, delayed, and frequency altered. For each auditory feedback condition, subjects read at both a normal and a fast rate. Results indicated that stuttering frequency was significantly decreased during conditions of delayed and frequency altered auditory feedback at both speech rates (p < 0.05). These findings refute the notion that a slowed speech rate is necessary for fluency enhancement under conditions of altered auditory feedback. Considering previous research and the results of this study, it is proposed that there may be two interdependent factors that are responsible for fluency enhancement: alteration of auditory feedback and modification of speech production.
本研究调查了在两种不同语速的言语产生过程中，改变听觉反馈对口吃频率的影响。九名口吃者在阅读任务中表现出至少5%的不流畅，作为研究对象。他们阅读八篇不同的文章（每篇长度为300个音节），同时接受四种听觉反馈条件：未改变、掩蔽、延迟和频率改变。对于每种听觉反馈条件，研究对象分别以正常语速和快速语速进行阅读。结果表明，在两种语速下，延迟和频率改变的听觉反馈条件下，口吃频率均显著降低（p < 0.05）。这些发现驳斥了在改变听觉反馈条件下，减慢语速是提高流畅性所必需的这一观点。综合先前的研究和本研究的结果，有人提出，可能有两个相互依存的因素导致流畅性提高：听觉反馈的改变和言语产生的调整。
