英语方言中最基本的划分是卷舌音/非卷舌音的划分。历史上/r/-loss音变化的机制还没有很好的理解，但研究当代/r/-loss音变化的rhotic各种英语可以提供新的见解。我们知道，/r/弱化在当代苏格兰英语是一个手势定时为基础的现象，它是社会索引，但我们没有语音解释弱/r/变体在话语的最后位置的优势。本研究利用社会分层的会话超声舌成像语音语料库，探讨了边界语境，沿着其他语言和社会因素，如音节重音，后续辅音的地方和社会阶层，对/r/和强度的舌手势时间的影响。混合效应模型确定，话语的最后上下文条件更大的前舌手势延迟/r/和较弱的声音/r/s，但只在工人阶级的讲话。中产阶级的讲话显示/r/在话语最终位置没有前舌手势延迟，并且/r/在该位置被可听加强。目前还不清楚这种分歧是由于在这些社会阶层社区/r/的潜在舌头形状的变化，或者是否话语的最后位置提供了一个关键位置的性能的社会阶层使用/r/的显着变化。
The most fundamental division in English dialects is the rhotic/non-rhotic division. The mechanisms of historical /r/-loss sound change are not well understood, but studying a contemporary /r/-loss sound change in a rhotic variety of English can provide new insights. We know that /r/ weakening in contemporary Scottish English is a gesture-timing based phenomenon and that it is socially indexical, but we have no phonetic explanation for the predominance of weak /r/ variants in utterance-final position. Using a socially-stratified conversational ultrasound tongue imaging speech corpus, this study investigates the effects of boundary context, along with other linguistic and social factors such as syllable stress, following-consonant place and social class, on lingual gesture timing in /r/ and strength of rhoticity. Mixed-effects modelling identified that utterance-final context conditions greater anterior lingual gesture delay in /r/ and weaker-sounding /r/s, but only in working-class speech. Middle-class speech shows no anterior lingual gesture delay for /r/ in utterance-final position and /r/ is audibly strengthened in this position. It is unclear whether this divergence is due to variation in underlying tongue shape for /r/ in these social-class communities, or whether utterance-final position provides a key location for the performance of social class using salient variants of /r/.
