本研究旨在描述言语过程中唇律协调的发展，并评估言语运动发展对语音发展的潜在影响。从四个年龄组的说话者中观察到含有双唇辅音的音节的产生（即，1岁、2岁、6岁和年轻人）。一个基于视频的运动跟踪系统被用来描述上唇、下唇的运动和规律。这些发音姿势的协调组织在生命的最初几年发生了巨大的变化，并在6岁以后继续进行完善。目前的研究结果是一致的唇和法律协调的发展的三个主要阶段的讲话：整合，分化和完善。这些发展过程中的每一个都需要存在不同的协调限制早期发音运动。这表明，这些限制将有可预测的后果，语音发展的顺序。
This investigation was designed to describe the development of lip and law coordination during speech and to evaluate the potential influence of speech motor development on phonologic development. Productions of syllables containing bilabial consonants were observed from speakers in four age groups (i.e., 1-year-olds, 2-year-olds, 6-year-olds, and young adults). A video-based movement tracking system was used to transduce movement of the upper lip, lower lip, and law. The coordinative organization of these articulatory gestures was shown to change dramatically during the First several years of life and to continue to undergo refinement past age 6. The present results are consistent with three primary phases in the development of lip and law coordination For speech: integration, differentiation, and refinement. Each of these developmental processes entails the existence of distinct coordinative constraints on early articulatory movement. It is suggested that these constraints will have predictable consequences For the sequence of phonologic development.
