本研究分析了10名学习苏格兰英语的儿童所产生的无齿牙槽擦音和后牙槽擦音的频谱和舌形动力学。同步超声舌象数据和声学数据被用来验证儿童的语音对比的产生。六个孩子一贯准确的生产摩擦目标,与一些跨辅音语音差异的方向先前表现为年龄较大的儿童和成人,以及一些不成熟的声学和发音的动态模式。仪器分析可以描述舌形的音位错误和语音失真的实现。有一些证据表明,发音的对比在产生知觉的对比之前。观察到的模式可以解释为复杂的发音要求摩擦生产,结合发展控制的发音器官。本文最后讨论了语音理论和言语治疗实践的结果的影响。
The study analysed spectral and tongue shape dynamics of voiceless alveolar and postalveolar fricatives produced by ten children learning Scottish English. Synchronised ultrasound tongue imaging data and acoustic data were used to characterise children's productions of the phonemic contrast. Six children had consistently accurate productions of both fricative targets, with some cross-consonant phonetic differences in the direction previously demonstrated for older children and adults, as well as some immature acoustic and articulatory dynamic patterns. Instrumental analyses made it possible to describe tongue shape for phonemic errors and phonetically distorted realisations. There was some evidence of articulatory contrast in production preceding contrast in perception. The observed patterns can be explained by the complex articulatory demands on the fricative production, in combination with the developing control of articulators. The paper concludes by discussing the implications of the results for phonological theory and for speech therapy practice.
