This study examines the influence of bilingual status, language-internal (complexity of L1 phonology), language-external (dominance), and lexical (L2 vocabulary score) factors on phonological production in French-speaking monolingual (n = 37) and bilingual children (n = 64) aged three to six years. Children participated in an object and picture naming task which tested different phonological features. The bilinguals' first languages were coded in terms of the complexity of these phonological features. In addition, the parents completed a questionnaire on their child's language dominance and the children were administered a vocabulary test in their L2. Results indicated that vocabulary was the principal predictor of phonological accuracy across both age groups. Apparent monolingual-bilingual differences and dominance effects could largely be explained by vocabulary scores: children who scored better on a vocabulary test obtained superior phonological accuracy. Language-internal effects were minimal and marginally influenced vowel accuracy only.
本研究考察了双语状态、语言内部（母语语音复杂性）、语言外部（主导地位）和词汇（第二语言词汇得分）因素对法语单语儿童（n=37）和双语儿童（n=64）在三到六岁时语音产生的影响。儿童参与了一项物体和图片命名任务，该任务测试了不同的语音特征。双语者的第一语言根据这些语音特征的复杂性进行编码。此外，父母还完成了一份关于孩子语言主导地位的问卷，孩子还参加了他们第二语言的词汇测试。结果表明，词汇是两个年龄组语音准确性的主要预测因素。明显的单语-双语差异和主导地位效应在很大程度上可以用词汇分数来解释：在词汇测试中得分更高的孩子获得了更高的语音准确性。语言内部因素的影响很小，仅对元音准确性有一定影响。
