Phonological development of first language isiXhosa-speaking children aged 3;0–6;0 years: A descriptive cross-sectional study

Abstract

Standardized assessments of children’s isiXhosa phonology have not yet been developed and there is limited information about developmental norms in this language. This article reports on the phonological development of 24 typically developing first language isiXhosa-speaking children aged 3;0–6;0 years, in Cape Town, South Africa. The order and age of acquisition of isiXhosa phonemes, emergence and elimination of phonological processes and percentage consonants and vowels correct are described. A set of culturally and linguistically appropriate pictures was used to elicit single word responses that were recorded and transcribed. The study found that children had acquired most isiXhosa phonemes by 3;0 years although aspirated plosives, affricates, fricatives and clicks were still developing. In particular, the affricates and aspirated plosives were still developing in the 5-year-old children in this sample, suggesting that these may be the latest acquired segments. Children were able to produce basic word shapes by 3;0 years, but some of the words of 4–6 syllables were still being mastered by the 4- and 5-year-old children. Phonological processes that have been well documented for other languages were used by children in this sample (e.g. deaffrication, stopping and gliding of liquids). Findings presented for this pre-school-aged sample are related to theories of phonological acquisition to provide normative data on phonological development in isiXhosa-speaking children.
