The current distribution of Bantu languages is commonly considered to be a consequence of a relatively recent population expansion (3-5kya) in Central Western Africa. While there is a substantial consensus regarding the centre of origin of Bantu languages (the Benue River Valley, between South East Nigeria and Western Cameroon), the identification of the area from where the population expansion...

Tone in Bantu languages is rarely studied experimentally. This paper reports a production study which reveals the intricate interaction of tonal context and morphological structure in surface tone realization in Sepedi, a South African Bantu language.

Examination of a set of non-Bantu Niger-Congo languages shows that most are aspect-prominent languages, that is, they either do not encode tense —the majority case— or, as the quotation indicates, there is reason to think that some have added tense to an original aspectual base. Comparative consideration of tense-aspect categories and morphology suggests that early and Proto-Niger-Congo were as...

Linguistic divergence occurs after speech communities divide, in a process similar to speciation among isolated biological populations. The resulting languages are hierarchically related, like genes or species. Phylogenetic methods developed in evolutionary biology can thus be used to infer language trees, with the caveat that 'borrowing' of linguistic elements between languages also occurs, to...

The majority of sub-Saharan Africans today speak a number of closely related languages collectively referred to as 'Bantu' languages. The current distribution of Bantu-speaking populations has been found to largely be a consequence of the movement of people rather than a diffusion of language alone. Linguistic and single marker genetic studies have generated various hypotheses regarding the tim...

There are many reasc~s for wanting to measure the degree of phoae-tic similarity between members of a group of languages or dialects. The present study grew out of a research project which was designed to get data that might have a bearing on some of the practical problems which exist in Uganda. In the Southern part of Uganda, where two thirds of the nine million people live, there are numerous...

This paper is concerned with two types of word-level asymmetries and their interaction: leftright asymmetries and stem-word asymmetries. Two left-right asymmetries are examined from a wide range of languages, one morphological (the predominance of suffixation over prefixation), one phonological (the preference for anticipatory over perseverative phonology). Since phonological processes are ofte...

Much is already known about the prosodic systems of the indigenous South African languages from descriptions and analyses in the existing literature. All of the existing work has been carried out in the field of African studies or formal linguistics. In order to be able to implement the generalisations obtained into computational models in speech processing, the existing sources and results mus...
