成年人的语音表征通常被认为包括音素层面的子词汇信息。然而，有些人认为，幼儿的词汇表征更全面。如果幼儿使用整词表征，而成人使用音素表征，那么语音发展的一个组成部分包括从整体到分段存储语音信息的过渡。本研究通过调查词汇习得第一年（1;0-2;0）词内产出变异的流行率和模式来探讨这种转变的性质。纵向数据从四个典型的发展中国家的儿童进行了分析，以确定在每个年龄段的变化。变异模式进行了讨论，在有关的实足年龄和生产词汇量。结果表明，高的整体率的变化，以及对应于组合语音的发病变化的峰值，这表明语音重组可能开始有点晚于以前认为的。
Phonological representation for adult speakers is generally assumed to include sub-lexical information at the level of the phoneme. Some have suggested, however, that young children operate with more holistic lexical representations. If young children use whole-word representation and adults employ phonemic representation, then a component of phonological development includes a transition from holistic to segmental storage of phonological information. The present study addresses the nature of this transition by investigating the prevalence and patterns of intra-word production variability during the first year of lexical acquisition (1;0-2;0). Longitudinal data from four typically developing children were analysed to determine variability at each age. Patterns of variability are discussed in relation to chronological age and productive vocabulary size. Results show high overall rates of variability, as well as a peak in variability corresponding to the onset of combinatorial speech, suggesting that phonological reorganization may commence somewhat later than previously thought.
