摘要： 目的观察发展性口吃者朗读汉语四字词时的言语产出异常并初步探讨其发生机制。方法应用语音反应时实验范式,采用计算机语音数据采集和语音分析技术,比较发展性口吃者与对照者之间朗读四字词的言语产出成绩。结果口吃组语音持续时间(VDT)为(791±82)ms,明显长于对照组(687±93)ms(t=3.42,P<0.01);但语音错误率(VER)和语音反应时(VRT)与对照组之间无显著性差异。结论发展性口吃者的言语流畅性障碍主要发生在言语运动阶段,可能与同时性语言加工任务干扰了言语产出任务有关。

Abstract: Objective To observe the abnormalities of speech production when developmental stutterers reading four-character Chinese words aloud and to discuss its etiology mechanisms. Methods The speech production results between the developmental stutterers and normal speakers when reading four-character Chinese words under the voice reaction time paradigm and computerize program in acoustic data analysis were compared. Results The voice duration time (VDT) of developmental stuttering group (791±82) ms was longer than that of the control group (687±93) ms (t=3.42,P<0.01),but the differences of voice reaction time (VRT) and voice error rate (VER) were not significant between these two groups. Conclusion The speech fluency disorders of developmental stuttering maybe mainly exist in the stage of speech movement, and probably due to the speech production disturbed with language processing.
