The purpose of this study was to compare the onsets, offsets, and durations of respiratory, articulatory, and laryngeal behaviors associated with the perceptually fluent speech of young stutterers (n = 8) to those of their normally fluent peers (n = 8). Simultaneous recordings of the targeted behaviors were made using noninvasive, minimally intrusive instrumentation. Specific temporal parameters of coordination--onsets, offsets, and durations of muscle activity and structural movement--were assessed within a particular component of the speech production system (e.g., onset of lower lip closing relative to lower lip opening muscle activity) as well as between different components (e.g., onset of rib cage deflation relative to onset of vocal fold contact for voicing). Results indicated that there were neither statistically significant nor apparent differences between the perceptually fluent speech of young stutterers and that of their normally fluent peers in terms of selected temporal characteristics of coordination. Findings suggest that the molar temporal characteristics of coordination for young stutterers' fluent speech production(s) are not appreciably different from those of their normally fluent peers and further, any temporal characteristics of stutterers' fluent speech that do differ from normal are probably brief, as well as subtle, in nature.
本研究的目的是比较8名年轻口吃者与8名正常流利同龄人在感知上流利言语时的呼吸、发音和喉部行为的起始、结束及持续时间。使用非侵入性、微创仪器对目标行为进行同步记录。在言语产生系统的特定组成部分内（如下唇闭合相对于下唇张开肌肉活动的起始）以及不同组成部分之间（如胸廓收缩起始相对于发声时声带接触起始）评估协调的特定时间参数——肌肉活动和结构运动的起始、结束及持续时间。结果表明，在选定的协调时间特征方面，年轻口吃者与正常流利同龄人在感知上流利言语之间既无统计学显著差异，也无明显差异。研究结果表明，年轻口吃者流利言语产生的整体时间特征与正常流利同龄人相比并无明显差异，而且，口吃者流利言语中任何与正常不同的时间特征可能在本质上也是短暂且细微的。
