The purpose of the study was to develop a core vocabulary list based on language samples from Sepedi-speaking children, in order to make it available as a resource to inform vocabulary selection for augmentative and alternative communication (AAC) systems for children in need of AAC from a Sepedi language background. METHOD : The speech of six typically developing Sepedi-speaking children aged 5–6 years was recorded using small body-worn audio recording devices. Children were recorded during their regular pre-school day. The recordings were transcribed, coded and analysed. RESULT : The composite transcript consisted of 17 579 words, of which 1023 were different words. The core vocabulary was determined by identifying all words that were used with a minimal frequency of 0.05%, and were used by at least half of the participants. The Sepedi core vocabulary consisted of 226 words that accounted for 88.1% of the composite sample. CONCLUSION : The core vocabulary determined in this study represents a small pool of reusable linguistic elements that form the grammatical framework of the Sepedi language. As such, is a valuable resource that can be used to assist with vocabulary selection for children who require AAC and who come from a Sepedi language background.en© 2020 Taylor & Francis Group.
