The primary purpose of this study was to determine if the finding of Kalinowski et al. (1993) of dramatic reductions in stuttering under delayed auditory feedback (DAF) at normal and fast speech rates could be replicated. The second purpose was to determine if stuttering frequency is differentially affected by various delays in an attempt to identify the optimal delay for fluency enhancement for both normal and fast speech rates. Fourteen adult stutterers read eight different passages at either a normal or fast speech rate under non-altered auditory feedback (NAF) and DAF with delays of 25, 50 and 75 ms. Results showed that significant fluency enhancement occurred under DAF at both normal and fast speech rates at all DAF settings (p < 0.05). This finding corroborates the notion that a slowed rate of speech is not a necessary antecedent for fluency improvement under conditions of altered auditory feedback. In addition, the results indicated that 50 ms appears to be the shortest delay producing the maximum reduction in stuttering frequency.
本研究的主要目的是确定能否复制卡利诺夫斯基等人（1993年）的研究结果，即在正常语速和快速语速下，延迟听觉反馈（DAF）能显著减少口吃现象。第二个目的是确定口吃频率是否会受到不同延迟的差异影响，以便为正常语速和快速语速找到提高流畅度的最佳延迟时间。14名成年口吃者在未改变听觉反馈（NAF）以及延迟25、50和75毫秒的DAF条件下，以正常或快速语速朗读八篇不同的文章。结果表明，在所有DAF设置下，正常语速和快速语速时，DAF都能显著提高流畅度（p < 0.05）。这一发现证实了以下观点：在听觉反馈改变的情况下，语速减慢并非提高流畅度的必要前提。此外，结果表明，50毫秒似乎是使口吃频率降幅最大的最短延迟时间。
