Despite the fact that in most communities interaction occurs between the child and multiple speakers, most previous research on input to children focused on input from mothers. We annotated recordings of Sesotho-learning toddlers living in non-industrial Lesotho in South Africa, and French-learning toddlers living in urban regions in France. We examined who produced the input (mothers, other children, adults), how much input was child directed, and whether and how it varied across speakers. As expected, mothers contributed most of the input in the French recordings. However, in the Sesotho recordings, input from other children was more common than input from mothers or other adults. Child-directed speech from all speakers in both cultural groups showed similar qualitative modifications. Our findings suggest that input from other children is prevalent and has similar features as child-directed from adults described in previous work, inviting cross-cultural research into the effects of input from other children.

尽管在大多数社区中，儿童和多个说话者之间发生了互动，但之前大多数关于儿童输入的研究都集中在母亲的输入上。我们注释了生活在南非非工业化莱索托的学习塞索托语的幼儿和生活在法国城市地区的学习法语的幼儿的录音。我们检查了谁产生了输入（母亲、其他孩子、成人），有多少输入是由孩子指挥的，以及它是否以及如何在不同的扬声器中变化。正如预期的那样，母亲在法语录音中贡献了大部分输入。然而，在塞索托的录音中，来自其他孩子的输入比来自母亲或其他成年人的输入更常见。来自两个文化群体的所有演讲者的面向儿童的演讲都表现出相似的定性变化。
