This project replicates and extends previous work on coarticulation in velar-vowel sequences in English. Coarticulatory data for 46 young adult speakers, 23 who stutter and 23 who do not stutter show coarticulatory patterns in young adults who stutter that are no different from typical young adults. Additionally, the stability of velar-vowel production is analysed in token-to-token variability found in multiple repetitions of the same velar-vowel sequence. Across participants, identical patterns of coarticulation were found between people who do and do not stutter, but decreased stability was found in velar closure production in a significant subset of people who stutter. Other people who stutter appeared no different than typical speakers. Outcomes of this study suggest that articulatory maturation in young adults who stutter is, on average, no different from typical young adults, but that some young adults who stutter could be viewed as having less stably activated articulatory sub-systems.
本项目复制并扩展了之前关于英语中软腭音与元音序列协同发音的研究。46名年轻成年说话者（23名口吃者和23名非口吃者）的协同发音数据显示，口吃的年轻成年人的协同发音模式与典型的年轻成年人并无差异。此外，在同一软腭音与元音序列的多次重复中发现的逐次差异中，分析了软腭音与元音发音的稳定性。在所有参与者中，口吃者和非口吃者之间发现了相同的协同发音模式，但在相当一部分口吃者中，软腭闭合发音的稳定性有所下降。其他口吃者与典型说话者没有差异。本研究结果表明，平均而言，口吃的年轻成年人的发音成熟度与典型的年轻成年人没有差异，但一些口吃的年轻成年人可能被视为具有激活不太稳定的发音子系统。
