Abstract
ABSTRACT 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.
