生成音系学家使用对比最小对来确定语言中的功能音系单位。这种技术已被扩展到临床目的，以获得音位库存与语音障碍的儿童，提供一个给定的儿童的语音系统，是有用的评估，治疗和进展监测的定性分析。在这项研究中，我们检查了来自可学习性项目（Gierut，2015 b）的275名语音障碍儿童的单字产出，以确认音素库存（一种语音知识的测量）和辅音准确性之间的关系-一种定量的关系测量，直接将儿童的语音产出与目标（即成人样）形式进行比较。此外，我们确定了潜在的百分比准确性的截止分数，可靠地分类的声音在或出一个孩子的音素库存在不同长度的语音声音探头。我们的研究结果表明，高达90%的英语辅音的音素功能，可以确定的百分比准确性为学龄前儿童与语音障碍时，一个足够大的和彻底的语音样本。
Generative phonologists use contrastive minimal pairs to determine functional phonological units in a language. This technique has been extended for clinical purposes to derive phonemic inventories for children with phonological disorder, providing a qualitative analysis of a given child's phonological system that is useful for assessment, treatment, and progress monitoring. In this study, we examine the single-word productions of 275 children with phonological disorder from the Learnability Project (Gierut, 2015b) to confirm the relationship between phonemic inventory - a measure of phonological knowledge - and consonant accuracy - a quantitative, relational measure that directly compares a child's phonological productions to the target (i.e. adult-like) form. Further, we identify potential percentage accuracy cutoff scores that reliably classify sounds as in or out of a child's phonemic inventory in speech-sound probes of varying length. Our findings indicate that the phonemic function of up to 90% of English consonants can be identified from percentage accuracy for preschool-age children with phonological disorder when a sufficiently large and thorough speech sample is used.
