This methodological study in 33 two-year-olds shows that child speech (total utterances, word roots, MLU) occurs at about the same level in different settings (the familiar home vs. the unfamiliar laboratory), but that children speak more and in more differentiated ways with different people (mother vs. stranger). Child speech also shows significant short-term stability. Girls use more different word roots and speak in longer utterances than do boys. In spontaneous child speech, cross-context generalizations appear warranted, but they also depend on conversational partner and gender of child.
这项针对33名两岁儿童的方法学研究表明，儿童言语（总话语量、词根、平均语句长度）在不同环境（熟悉的家庭与不熟悉的实验室）中的出现水平大致相同，但儿童与不同的人（母亲与陌生人）交谈时，说话更多且方式更具差异性。儿童言语也显示出显著的短期稳定性。女孩比男孩使用更多不同的词根，并且话语更长。在儿童自发言语中，跨情境的概括似乎是合理的，但这也取决于对话伙伴和儿童的性别。
