    Abstract

    In this study, we analysed phonetic and phonological consonant characteristics of cleft palate speech (CPS) at ages 5 and 10 in cleft palate with/without cleft lip (CP±CL) based on Cleft Audit Protocol for Speech – Augmented (CAPS-A) data collected in the Dental Hospital in Glasgow. The nature and extent of CPS characteristics at different ages were investigated. Video-recordings of 42 cleft palate (CP), unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP) boys and girls were analysed based on narrow transcription and automatic PROPH (profile of phonology) of types of articulation features. Results of this study showed that CP±CL children produce a significantly higher number of phonetic CPS characteristics than phonological processes at both ages.
