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 (fo), and fo variability (foSD) 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 foSD, 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 foSD in English may be due to linguistic fo 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.
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.
