Normative database of word production of Putonghua-speaking children — Beijing articulahon norms project: CASS_CHILD_WORD

The database is based on normative data of the phonological development of Putonghua-speaking children. Single word production of around 4000 normally-developing Putonghua-speaking children aged between 1;6 and 6;0 years in Beijing city proper was collected. The speech samples were obtained through picture-naming task. What was of primary concerns were the order of the acquisition of speech sounds and the typical error patterns in normally-developing children within different age bands. The normative data can offer reference for theoretical exploration, clinical assessment, intervention and rehabilitation, and help improve children speech recognition.
