As part of a special issue on case profiles in protracted phonological development (PPD), we present a Mandarin-speaking three-year-old boy from Shanghai with severe PPD and no other developmental concerns. In comparison with typically developing (TD) children and a peer group from Shanghai with PPD, he had a very low Whole Word Match score (3.7% of words matched the adult targets exactly), reflecting severe constraints on word structure, consonants and diphthongs/triphthongs. His phonological output resembled that of younger children in its absence of fricatives, liquids and diphthongs/triphthongs alongside fairly high match for word length, tones and monophthongs, labials /p/ and /m/ and dorsal /k/. However, less expected was a pervasive glottal stop substitution in onset. The analysis describes his needs in detail but also strengths that could be exploited in phonological intervention.
作为关于迁延性语音发育障碍（PPD）病例特征的特刊的一部分，我们呈现了一个来自上海、患有严重 PPD 但无其他发育问题的 3 岁男孩。与典型发育（TD）儿童和上海患有 PPD 的同龄组相比，他的整体词匹配得分非常低（只有 3.7%的词与成人目标完全匹配），这反映出他在词结构、辅音和双元音/三元音方面受到了严重限制。他的语音输出与没有摩擦音、流音和双元音/三元音的更年幼的儿童相似，而在词长、音调和单元音、唇音/p/和/m/以及后舌音/k/方面的匹配度则相当高。然而，出乎意料的是，在起始音中存在普遍的声门塞替代音。该分析详细描述了他的需求，但也指出了在语音干预中可以利用的优势。
