This study examined Voice Onset Time (VOT) in monolingual and bilingual French-speaking children, aged 3 to 6 years (n = 42), and in monolingual adults (n = 15). The bilinguals consisted of those acquiring languages with a long lag – short lag (Bi – Long) and those acquiring languages with a lead – short lag contrast (Bi – Lead). We predicted differences between monolinguals and Bi – Long but no differences between monolinguals and Bi – Lead, given that children in the latter group have the same voicing contrast as French. Children and adults played a Memory game in which they produced target words containing stop consonants in word-initial position. Analyses examined the effect of bilingualism and control variables (age, place of articulation (PoA), vowel type) on positive VOT values and on the presence of lead voicing. Results indicated that monolinguals and both groups of bilinguals produced target voiced and voiceless stops with positive VOTs of similar magnitude. Nevertheless, Bi – Long children who were not dominant in French had longer VOTs than monolinguals, consistent with an influence of the L1 on French. Bi – Long children also produced marginally fewer tokens with lead voicing than monolinguals. In addition, results indicated that age, PoA, and vowel type influenced VOT.

这项研究调查了3至6岁的单语和双语法语儿童（n  =  42）和单语成年人（n  =语音发声时间（VOT） 15）。双语者包括那些具有长时滞-短时滞（Bi-Long）的语言，以及那些拥有领先-短时滞对比度（Bi-Lead）的语言。我们预计单语者和Bi–Long之间的差异，但单语者和Bi–Lead之间没有差异，因为后一组的孩子的发音对比与法语相同。儿童和成人玩记忆游戏，他们在目标词中产生包含停止辅音的目标词。分析检查了双语和控制变量（年龄，发音部位（PoA），元音类型）对正VOT值和主发音的影响。结果表明，单语者和两组双语者产生了具有相似幅度的正VOT的目标有声和无声停止。尽管如此，Bi –在法语中不占主导地位的长子的VOT比单语者长，这与L1对法语的影响一致。Bi –长孩子用铅发声的代币也比单语者少。此外，结果表明年龄，PoA和元音类型也会影响VOT。
