This paper presents acoustic and articulatory data from prevocalic /r/ in the non-rhotic variety of English spoken in England, Anglo-English. Although traditional descriptions suggest that Anglo-English /r/ is produced using a tip-up tongue configuration, ultrasound data from 24 speakers show similar patterns of lingual variation to those reported in rhotic varieties, with a continuum of possible tongue shapes from bunched to retroflex. However, the number of Anglo-English speakers using exclusively tip-up variants is higher than that reported in American English across all phonetic contexts. It is generally agreed that English /r/ may be labialised, but the exact contribution of the lips has yet to be explored. Lip camera data reveal significantly more lip protrusion in bunched tongue configurations than retroflex ones. These results indicate that the differing degrees of lip protrusion may contribute to maintaining a stable acoustic output across the different tongue shapes. An articulatory-acoustic trading relation between the sublingual space and the degree of lip protrusion is proposed. Finally, we suggest that Anglo-English /r/ has a specific lip posture which differs from that of /w/. We relate the development of such a posture to Anglo-English speakers’ exposure to labiodental variants and to the pressure to maintain a perceptual contrast between /r/ and /w/.

本文介绍了在英国非英语的非rhotic变体中，provocalic / r /的声音和发音数据。尽管传统的描述表明盎格鲁英语/ r /是使用向上倾斜的舌头配置制作的，但来自24位说话者的超声数据显示出与流变品种中报道的语言相似的舌头变异模式，并且可能出现连续的舌头形状，从成束到反折。但是，在所有语音环境中，仅使用小费改型的盎格鲁英语使用者的人数高于美国英语。人们普遍认为，英语/ r /可以用重音符号表示，但嘴唇的确切作用尚待探讨。唇部摄像头数据显示，成束舌头配置中的唇部突出明显多于反折舌头。这些结果表明，不同程度的嘴唇突出可能有助于在不同的舌头形状上保持稳定的声音输出。提出了舌下空间与嘴唇突出程度之间的发音-交易关系。最后，我们建议盎格鲁英语/ r /具有与/ w /不同的特定唇形。我们将这种姿势的发展与英语母语者暴露在唇齿间的变体以及保持/ r /和/ w /之间的感知对比的压力联系起来。我们建议盎格鲁英语/ r /的唇形不同于/ w /。我们将这种姿势的发展与英语母语者暴露在唇齿间的变体以及保持/ r /和/ w /之间的感知对比的压力联系起来。我们建议盎格鲁英语/ r /的唇形不同于/ w /。我们将这种姿势的发展与英语母语者暴露在唇齿间的变体以及保持/ r /和/ w /之间的感知对比的压力联系起来。
