Findings from Hong Kong Polytechnic University Provides New Data about Apraxias (Research Article Acoustic Analyses of Tone Productions In Sequencing Contexts Among Cantonese-speaking Preschool Children With and Without Childhood Apraxia of...).

A recent study conducted by researchers at Hong Kong Polytechnic University examined the fundamental frequency (F0) changes within syllables and the effects of syllable structure, lexical status, and syllable positions on F0 in Cantonese-speaking preschool children with and without childhood apraxia of speech (CAS). The study found that children with CAS had difficulty in varying F0 within syllables compared to those without CAS, indicating pitch variation difficulty and language-specific impairment profiles in CAS. The researchers suggest further investigations using objective measures to identify Cantonese speakers with CAS and cross-linguistic investigations using growth curve analysis and the tone sequencing task (TST).
