使用多种语言的临床研究者已经注意到，眼轮匝肌发展较晚，并且容易出现临床上显著的发音错误。英语的卷舌音近音和西班牙语的卷舌颤音表现出舌头形状的差异之间的初级收缩沿着腭和次级收缩在咽部。这种区别在发音错误中常常被忽略。在这项工作中，我们推测是否在英语中看到的第二咽关节也可能是一个跨语言的特性rhotics，从而潜在的一个因素，在发音延迟和发音错误。我们描述了一个探索性的研究，分析从一个小样本的英语，马拉雅拉姆语，法语，波斯语和西班牙语为母语的成年人的超声视频中的卷舌配置。我们的研究结果证实，最有可能表现出后期掌握和发音错误的卷舌音也涉及到舌根向咽部收缩的运动，但这一结论必须在没有进一步研究的情况下保持暂时性。与此同时，临床策略，包括注意舌根以及舌前配置（如促进上下文与舌根运动）可能是值得探索的矫正不同语言的发音错误。
Clinical investigators working in a number of languages have noted that rhotics develop late and are subject to clinically significant misarticulations. The English rhotic approximant and the Spanish rhotic trill exhibit tongue shape differentiation between a primary constriction along the palate and a secondary constriction in the pharynx. This differentiation is often missing in misarticulations. In this work, we speculate whether the secondary pharyngeal articulation seen in English might also be a cross-linguistic characteristic of rhotics and thus potentially a factor in articulatory delays and misarticulations. We describe an exploratory study analyzing rhotic tongue configurations in ultrasound videos from a small sample of native adult speakers of English, Malayalam, French, Persian and Spanish. Our findings confirm that rhotic sounds most likely to show late mastery and misarticulation also involve tongue root movement toward a pharyngeal constriction, but this conclusion must remain tentative without further research. In the meantime, clinical strategies that include attention to tongue root as well as tongue front configuration (such as facilitative contexts with tongue root movement) may be worth exploring in remediation of rhotic misarticulations across languages.
