It was about one and a half years ago that I finally I arrived where I had always wanted to be and do what I had always wanted-- teach students, support small language communities and conduct research on African languages on my doorstep. The University of Cape Town and my new colleagues welcomed my efforts to establish the Centre for African Language Diversity-- CALDi as well as The African Language Archive-- TALA and I was recently appointed the Mellon Research Chair: African Language Diversity this initiative. The main aim of CALDi is to train young African scholars in descriptive linguistics and open up space for research into African languages at UCT with the hopes of countering the dominance of African linguistics outside the continent. It has been a great challenge for which my whole career has been a form of preparation...Read more

The development of phonological categories in children's perception of final voicing in dialects of English
Adult speech perception is characterized by perceptual integration which gives rise to trading relations: less evidence from one acoustic property can be offset by more evidence from another. This dissertation reports perceptual experiments with young children native in different dialects of English.
Identification results indicate that in perceiving final stop voicing, young children differ from adults in predominantly using either vowel duration or first formant offset frequency, rather than both. Which property children use appears to be a function of dialect background. Discrimination results suggest that integration may develop, at least for some contrasts, on the basis of learning patterns of covariation in the native language, with implications for theories of speech perception.
