Abstract

Purpose: The purpose of this study was to investigate the cross-linguistic influences of Jamaican Creole (JC) and English on phonemic and vocal development in bilingual JC-English-speaking preschoolers.

Method: Sixteen typically developing children (12 females, M = 4 years; 4 months) completed the Diagnostic Evaluation of Articulation in Phonology Word Inconsistency Assessment subtest in JC and in English. Acoustic measures of voice onset time (VOT), VOT variability (VOT SD), mean fundamental frequency (f_o), and f_o variability (f_o SD) were extracted from each target word. Prevoicing was noted. Mixed models and regression models were analysed to understand the patterns of acoustic measures in each language, and the relationship between phonemic and vocal variability, respectively.

Result: Analyses showed a significant effect of language on f_o SD, wherein SD was greater in English than JC. JC spoken (percentage) was a significant positive predictor of VOT SD for voiced (short lag) productions. There was no relationship between phonemic and vocal variability measures.

Conclusion: Greater f_o SD in English may be due to linguistic f_o differences and speaking environment. Variability for voiced VOT is likely due to the continued maturation of vocal and articulatory control when children are developing adult-like productions, though longitudinal studies are needed.

双语学龄前儿童的音位和音高变异：牙买加克里奥尔语和英语的比较。

目的：本研究旨在调查牙买加克里奥尔语（JC）和英语对牙买加克里奥尔语-英语双语学龄前儿童的语音和发声发展的跨语言影响：16 名发育正常的儿童（12 名女性，男 = 4 岁 4 个月）分别用牙买加克里奥尔语和英语完成了语音发音诊断评估的单词不连贯评估子测试。从每个目标词中提取了发声时间 (VOT)、VOT 变异性 (VOT SD)、平均基频 (fo) 和 fo 变异性 (fo SD) 的声学测量值。注意到了前置发音。分析了混合模型和回归模型，以了解每种语言的声学测量模式，以及音位和发声变异性之间的关系：分析表明，语言对泡沫 SD 有明显影响，其中英语的 SD 比 JC 大。JC 口语（百分比）对发声（短滞后）的 VOT SD 有显著的正向预测作用。音位和发声变异性测量之间没有关系：结论：英语中更大的发声变异性可能是由于语言差异和口语环境造成的。发声 VOT 的变异性可能是由于儿童在发展类似成人的发音时，发声和发音控制不断成熟造成的，但还需要进行纵向研究。

期刊介绍： International Journal of Speech-Language Pathology is an international journal which promotes discussion on a broad range of current clinical and theoretical issues. Submissions may include experimental, review and theoretical discussion papers, with studies from either quantitative and/or qualitative frameworks. Articles may relate to any area of child or adult communication or dysphagia, furthering knowledge on issues related to etiology, assessment, diagnosis, intervention, or theoretical frameworks. Articles can be accompanied by supplementary audio and video files that will be uploaded to the journal’s website. Special issues on contemporary topics are published at least once a year. A scientific forum is included in many issues, where a topic is debated by invited international experts.
