We present a new approach to the investigation of dynamic ultrasound tongue imaging (UTI) data, applied here to analyse the subtle aspects of the fluency of people who stutter (PWS). Fluent productions of CV syllables (C = /k/; V = /ɑ, i, ə/) from three PWS and three control speakers (PNS) were analysed for duration and peak velocity relative to articulatory movement towards (onset) and away from (offset) the consonantal closure. The objective was to apply a replicable methodology for kinematic investigation to speech of PWS in order to test Wingate's Fault-Line hypothesis. As was hypothesised, results show comparable onset behaviours for both groups. Regarding offsets, groups differ in peak velocity. Results suggest that PWS do not struggle initiating consonantal closure (onset). In transition from consonantal closure into the vowel, however, groups appear to employ different strategies expressed in increased variation (PNS) versus decreased mean peak velocity (PWS).
我们提出了一种研究动态超声舌成像（UTI）数据的新方法，在此用于分析口吃者（PWS）言语流畅性的细微方面。分析了三名口吃者和三名对照者（非口吃者，PNS）的CV音节（C = /k/；V = /ɑ, i, ə/）的流畅发音，以研究相对于向辅音闭合（起始）和离开辅音闭合（结束）的发音运动的持续时间和峰值速度。目的是将一种可重复的运动学研究方法应用于口吃者的言语，以检验温盖特的断层线假说。正如所假设的，结果显示两组在起始行为上具有可比性。关于结束阶段，两组在峰值速度上存在差异。结果表明，口吃者在开始辅音闭合（起始）时并不困难。然而，在从辅音闭合过渡到元音时，两组似乎采用了不同的策略，表现为变化增加（非口吃者）与平均峰值速度降低（口吃者）。
