Analysis of phonological processes in the acquisition of complex onset in children with typical phonological development

ABSTRACT Objective: description and analysis of the phonological processes in the acquisition of complex onset by children with typical phonological development in the age ranges of 3;0 and 5;11. Methods: thirty-one students of a public day-care center in Maceió-AL, having no auditory, cognitive, or motor impairment, participated in this study. The data were collected using the ABFW Child Language Test (WERTZNER, 2004); spontaneous speech was also collected. Inferential statistical analysis of the data was performed, and the phonological processes were analyzed in the production of complex onset. Results: we found evidence for late acquisition of this syllabic component in the age range of 5;0-5;11 for both types of complex onsets. In relation to the prevalence of phonological processes, a statistically significant difference was observed between the different processes, with a prevalence of the simplified phonological process for C1V, when taking the two types of complex onset into consideration; however, the 5-year age group, in which there was a prevalence of liquid substitution, was an exception. Conclusion: the most observed phonological processes in children's speech were: simplification of C1V and liquid substitution. These results will contribute to the selection of the lexicon for evaluation and treatment of cases of atypical development.## 摘要 ### 研究目的 对年龄介于3;0至5;11岁的典型语音发育儿童在复杂复辅音声母（complex onset）习得过程中涉及的语音过程（phonological processes）进行描述与分析。 ### 研究方法 本研究招募了来自巴西阿拉戈斯州马塞约市一所公立日托中心的31名儿童，所有受试者均无听觉、认知或运动功能障碍。数据采集采用ABFW儿童语言测试（ABFW Child Language Test，WERTZNER, 2004），同时采集自发言语语料。随后对数据开展推断性统计分析，并针对复杂复辅音声母的产出情况展开语音过程分析。 ### 研究结果 两类复杂复辅音声母在5;0至5;11岁年龄段均存在习得延迟的证据。针对语音过程流行率的分析显示，不同语音过程的检出率存在统计学差异；综合两类复杂复辅音声母的整体数据来看，C1V简化语音过程的流行率最高，但5岁年龄组为例外，该组以流音替换（liquid substitution）为主。 ### 研究结论 儿童言语中最常见的语音过程为C1V简化与流音替换。本研究结果可为非典型语音发育个案的评估与治疗词汇选择提供参考依据。
