本研究的目的是通过考察发音和成人对所产生的音段的感知，更好地了解儿童是如何以及何时获得发音/L/(LEAP)和尾声/L/(PEELL)的。方法25名典型的3；0(岁；月)到7岁的澳大利亚说英语的儿童参与了一项诱发性模仿任务，在此过程中收集了音频、视频和语言的超声图像。这项研究的数据表明，对于澳大利亚英语学习的儿童来说，尾音/L/S的获得晚于首发/L/S，年龄较大的儿童在首发和尾音位置都产生更大比例的成人样/L/S，大致遵循美国英语学习儿童的既定标准。然而，尽管尾声/L/S的知觉与发音有关，但发音/L/S的发音几乎一致被认为是成年期的，尽管产生它们的发音有很大差异。结论儿童单胎发音/L/S的产生和知觉的差异与生理和语音发展有关。对未来的研究提出了建议，以梳理这些因素。
PurposeThe goal of this study was to better understand how and when onset /l/ (leap) and coda /l/ (peel) are acquired by children by examining both the articulations involved and adults' perceptions of the produced segments.MethodTwenty-five typically developing Australian English–speaking children aged 3;0 (years;months) to 7;11 participated in an elicited imitation task, during which audio, video, and lingual ultrasound images were collected. Transcribers perceptually rated audio, whereas video and ultrasound images were visually examined for the presence of adult-like articulations.ResultsData from this study establish that for Australian English–learning children, coda /l/s are acquired later than onset /l/s, and older children produce greater proportions of adultlike /l/s in both onset and coda positions, roughly following established norms for American English–speaking children. However, although perceptibility of coda /l/s was correlated with their articulations, onset /l/s were nearly uniformly perceived as adultlike despite substantial variation in the articulations used to produce them.ConclusionsThe disparity in the production and perception of children's singleton onset /l/s is linked to both physiological and phonological development. Suggestions are made for future research to tease these factors apart.
