Abstract

Purpose: To examine voice onset time (VOT) for the t-k contrast in bilingual Saudi Arabic and English speakers, comparing typically developing (TD) children and those suspected of speech sound disorders (sSSD).

Method: In a cross-sectional observational study, single-word productions of initial /t/ and /k/ were elicited from 88 children aged 3;0-9;11 (48 TD, 40 sSSD). VOT was measured acoustically and analysed by language, consonant, group, and age.

Results: In TD children, VOT was longer and more variable in English than Arabic, with a significant cross-language difference for /k/ only. Age correlated with Arabic /k/ VOT and trended for English /t/. In sSSD children, VOT was longer and more variable in Arabic, with significant /t/-/k/ differences.

Conclusion: The /t/-/k/ contrast revealed language- and group-specific VOT patterns, suggesting SSD may affect voicing timing differently across languages. Future work should include repeated tokens, word positions, and dialectal variants.

典型发育和疑似语言障碍的沙特双语儿童/t/和/k/发音时间模式

目的：通过比较正常发育儿童（TD）和疑似语音障碍儿童（sSSD），研究沙特阿拉伯语和英语双语者的语音起音时间（VOT）对t-k对比的影响。方法：在一项横断面观察研究中，从88名3岁、0-9岁的儿童中引出/t/和/k/的单字发音。11人（48人，40人）。用声学方法测量VOT，并按语言、辅音、分组和年龄进行分析。结果：在TD儿童中，英语的VOT比阿拉伯语的VOT更长，变化更大，只有/k/有显著的跨语言差异。年龄与阿拉伯语/k/ VOT相关，与英语/t/ VOT相关。在sSSD儿童中，阿拉伯语的VOT更长，变化更大，有显著的/t/-/k/差异。结论：/t/-/k/对比揭示了语言和群体特定的VOT模式，表明SSD可能对不同语言的发声时间产生不同的影响。未来的工作应该包括重复符号、单词位置和方言变体。
