To verify the effect of delayed auditory feedback on speech fluency of individuals who stutter with and without central auditory processing disorders.
The participants were twenty individuals with stuttering from 7 to 17 years old and were divided into two groups: Stuttering Group with Auditory Processing Disorders (SGAPD): 10 individuals with central auditory processing disorders, and Stuttering Group (SG): 10 individuals without central auditory processing disorders. Procedures were: fluency assessment with non-altered auditory feedback (NAF) and delayed auditory feedback (DAF), assessment of the stuttering severity and central auditory processing (CAP). Phono Tools software was used to cause a delay of 100 milliseconds in the auditory feedback. The "Wilcoxon Signal Post" test was used in the intragroup analysis and "Mann-Whitney" test in the intergroup analysis.
The DAF caused a statistically significant reduction in SG: in the frequency score of stuttering-like disfluencies in the analysis of the Stuttering Severity Instrument, in the amount of blocks and repetitions of monosyllabic words, and in the frequency of stuttering-like disfluencies of duration. Delayed auditory feedback did not cause statistically significant effects on SGAPD fluency, individuals with stuttering with auditory processing disorders.
The effect of delayed auditory feedback in speech fluency of individuals who stutter was different in individuals of both groups, because there was an improvement in fluency only in individuals without auditory processing disorder.
验证延迟听觉反馈对患有和未患有中枢听觉处理障碍的口吃者言语流畅性的影响。
参与者为20名7至17岁的口吃者，分为两组：患有听觉处理障碍的口吃组（SGAPD）：10名患有中枢听觉处理障碍的个体，以及口吃组（SG）：10名未患有中枢听觉处理障碍的个体。程序包括：使用未改变的听觉反馈（NAF）和延迟听觉反馈（DAF）进行流畅性评估，评估口吃严重程度和中枢听觉处理（CAP）。使用Phono Tools软件使听觉反馈延迟100毫秒。组内分析使用“Wilcoxon信号后测”，组间分析使用“Mann-Whitney”测试。
DAF导致SG组在统计学上有显著降低：在口吃严重程度量表分析中，类似口吃的不流畅频率得分、单音节词的阻塞和重复次数以及持续时间类似口吃的不流畅频率。延迟听觉反馈对SGAPD组（患有听觉处理障碍的口吃个体）的流畅性没有产生统计学上的显著影响。
延迟听觉反馈对两组口吃者言语流畅性的影响不同，因为只有未患有听觉处理障碍的个体的流畅性得到了改善。
