The identification of appropriate lexical segmentations of the speech signal constitutes a problem for the language learner and the child language researcher alike. Articulatory precision and fluency criteria for identifying formulaic expressions, sub-lexical forms and target lexemes in linguistic productions are defined and applied to the analysis of two Danish children's language development between the ages of 1;0 and 2;0. The results of this analysis are compared to the results of applying standard distributional and frequency criteria in the tabulation of mean length of utterance and vocabulary profiles for both standard and non-standard lexical segmentations. It is argued that although the two methods yield converging profiles of development during the latter part of the period studied, articulatory precision and fluency criteria offer a more powerful tool for identifying alternative segmentation strategies in early language acquisition. Profiles of vocabulary development for these two children suggest that the solution to the segmentation problem may be an important trigger for their vocabulary spurts.
对语音信号进行恰当的词汇切分，这对语言学习者和儿童语言研究者来说都是个问题。定义了用于识别语言产出中公式化表达、次词汇形式和目标词位的发音准确性和流畅性标准，并将其应用于分析两名丹麦儿童在1岁至2岁之间的语言发展情况。将这一分析结果与在标准和非标准词汇切分的话语平均长度和词汇概况列表中应用标准分布和频率标准的结果进行比较。研究认为，尽管在研究阶段的后期，这两种方法得出了趋同的发展概况，但发音准确性和流畅性标准为识别早期语言习得中的替代切分策略提供了更有力的工具。这两名儿童的词汇发展概况表明，切分问题的解决可能是他们词汇量激增的一个重要触发因素。
