Consistency of word production contributes to carers' ability to understand children's speech. Reports of the proportion of words produced consistently by typically developing preschool children, however, vary widely from 17% to 87%. This paper examines the quantitative (consistency count) and qualitative (e.g. phonemic analysis) characteristics of word consistency in 96 children aged 36-60 months. Children named 15 pictures twice, in separate trials, in the same assessment session. The mean consistency of the production for the whole group was 82%. Older children were more consistent than younger children. Girls were more consistent than boys. Words produced correctly in one trial and in error in another may indicate resolving error patterns. Words produced in error in two different ways provided useful evidence about the nature of inconsistent word production in typically developing children. The clinical and theoretical implications are discussed.
言语产出的一致性有助于照顾者理解儿童的言语。然而，关于正常发展的学龄前儿童一致性言语产出的比例，报告的范围从 17%到 87%不等。本文研究了 96 名 36-60 个月大的儿童在言语一致性的定量（一致性计数）和定性（例如音位分析）特征。儿童在同一评估时段的两次单独试验中命名 15 张图片。整个组的平均一致性为 82%。年龄较大的儿童比年龄较小的儿童更一致。女孩比男孩更一致。在一次试验中正确产生的词和在另一次试验中错误产生的词可能表明正在纠正错误模式。以两种不同方式错误产生的词为典型发展儿童的不一致言语产出的性质提供了有用的证据。讨论了临床和理论意义。
