In a previous study, Dodane and Bijeljac-Babic (2017) found that French/AmericanEnglish children aged 3;6 to 6;0, bilingual from birth, produced disyllabic words which had acoustic properties for lexical stress (f0, syllable duration and intensity) that differed from those of monolingual peers, showing cross-linguistic influences. In order to check whether these acoustic differences between the productions of bilingual children and those of their monolingual French- or American English-speaking peers were perceptible by native monolingual adults, we investigated the perception of these words by French and American English native speakers. Using an Elo rating task, participants were asked to indicate in each trial which word out of two competitors was produced by a bilingual child. Words were produced by French- or American English-speaking monolingual children and by two groups of bilinguals, one dominant in French and the other in American-English. The results clearly show that both French and American English monolingual adults were successful in distinguishing the bilingual children from their monolingual peers, but only if they were not dominant in the language of the raters. The relationship between the acoustic correlates of word stress produced by children and the perception of some "accent" by native adult speakers seems more intricate than expected and is further discussed.
在之前的一项研究中，Dodane 和 Bijeljac-Babic（2017 年）发现，3 岁半到 6 岁的说法语/英语的双语儿童，从出生起就是双语者，他们所产生的双音节词具有词汇重音的声学特征（基频、音节时长和强度），与单语者的特征不同，表现出跨语言的影响。为了检验双语儿童的发音与他们的单语法语或英语同伴的发音之间的这些声学差异是否能被母语为单语的成年人察觉，我们研究了这些单词在以法语和英语为母语的成年人中的感知情况。我们使用 Elo 评级任务，要求参与者在每次试验中指出两个竞争者中的哪一个词是由双语儿童产生的。这些词是由说法语或英语的单语儿童以及两组双语儿童产生的，一组以法语为主，另一组以美式英语为主。结果清楚地表明，法语和英语母语的成年人都成功地将双语儿童与他们的单语同伴区分开来，但前提是他们在评价者的语言中不占主导地位。儿童所产生的词重音的声学特征与母语为成年说话者对某些“口音”的感知之间的关系似乎比预期的更复杂，我们进一步讨论了这一关系。
