Many children learn language, in part, from the speech of non-native speakers who vary in their language proficiency. To investigate the influence of speaker proficiency on the quality of child-directed speech, 29 mothers who were native English speakers and 31 mothers who were native speakers of Spanish and who reported speaking English to their children on a regular basis were recorded interacting with their two-year-old children in English. Of the non-native speakers, 21 described their English proficiency as 'good', and eight described their English proficiency as 'limited'. ANCOVAs, controlling for differences in maternal education and child language level, revealed significant effects of group on lexical and grammatical properties of child-directed speech that the literature has identified as positive predictors of child language development. These results suggest that the child-directed speech of native speakers and non-native speakers with good proficiency provide a richer database for language acquisition than the child-directed speech of speakers with limited proficiency.
许多儿童在学习语言的过程中，部分是通过母语非英语者的语言输入，这些母语非英语者的语言熟练程度各有不同。为了研究说话者的熟练程度对儿童导向言语质量的影响，研究人员记录了 29 名以英语为母语的母亲和 31 名以西班牙语为母语但定期用英语与孩子交流的母亲与他们两岁的孩子用英语互动的情况。在非母语者中，21 人表示自己的英语水平“良好”，8 人表示自己的英语水平“有限”。在控制了母亲教育程度和儿童语言水平的差异后，协方差分析显示，母语者和英语熟练程度良好的非母语者的儿童导向言语在词汇和语法特征上存在显著差异，而这些特征是儿童语言发展的积极预测因素。这些结果表明，母语者和英语熟练程度良好的非母语者的儿童导向言语比英语熟练程度有限的说话者的儿童导向言语为语言习得提供了更丰富的数据库。
