This program of research will provide a better understanding of the early phonological development of children with cleft palate. Some children with cleft palate develop unusual speech patterns that have been labeled "compensatory" because they appear to be produced in response to an inability to achieve velopharyngeal closure and "maladaptive" because they are difficult to change once they have been established. Additionally, these patterns interfere with intelligibility and with the assessment of velopharyngeal function. Other children with similar structural problems do not develop these patterns. The studies proposed here will identify the factors associated with the development of undesirable articulation patterns and will describe the normal course of phonological development in children with cleft palate. This set of studies will follow a group of children with cleft palate and a matched group of normal children from the time they are 9 months old until they are 24 months old in an attempt to determine the origin and course of development of both adequate, appropriate phonological skills and compensatory patterns of articulation. All children will be seen once every three months. Additional speech samples will be obtained during the time children are learning to produce their first 50 words (all children). Acoustic analyses of the early vocalizations will be used to identify "speech-like" productions and both "speech-like" productions and meaningful words will be transcribed using standard IPA augmented by symbols designed for use with the speech of individuals with cleft palate. Within the cleft palate group, the relationship between the development of maladaptive compensatory articulation patterns (MCAP) in early speech and a number of factors will be examined. These factors include 1) hearing, 2) velopharyngeal competence, 3) the timing of primary palatal surgery relative to the onset of speech, and 4) the prelinguistic use of MCAP. The speech of children with cleft palate will be compared to the speech of non-cleft children to identify differences in the rate of acquisition of speech production milestones and differences in the frequency with which various phonemes and phoneme classes are targeted and produced by children with and without cleft palate.

这项研究计划将提供一个更好的了解早期 腭裂儿童的语音发育。有些孩子 腭裂发展出不寻常的语音模式， “补偿性”，因为它们似乎是对一种 无法实现咽闭合和“适应不良”，因为它们 一旦建立起来就很难改变。此外，本发明还 这些模式干扰了可理解性， 咽喉功能。其他有类似结构性问题的孩子也会这样做 而不是形成这些模式。这里提出的研究将确定 与不良发音发展相关的因素 模式，并将描述语音发展的正常过程中， 腭裂儿童 这组研究将跟踪一组腭裂儿童和一个 从9个月大到10个月大， 他们是24个月大，试图确定起源和过程， 发展适当的语音技能， 发音的补偿模式。每隔一段时间， 三个月在这段时间里， 孩子们正在学习产生他们的前50个单词（所有儿童）。 对早期发声的声学分析将用于识别 “类演讲”作品和“类演讲”作品和有意义的 单词将使用标准的国际音标转录， 用于腭裂患者的语音。在裂缝中 腭组适应不良的关系发展 早期言语中的补偿性清晰度模式（MCAP）和许多 将审查各种因素。这些因素包括1）听力，2） 腭部手术时机的选择 4）MCAP的前语言使用。的 腭裂儿童的语音将与 非唇裂儿童识别率的差异， 语音产生的里程碑和频率的差异， 各种音素和音素类是儿童的目标和产生的 有无腭裂
