Conference Paper
In this paper we model virtual buying cooperatives (VBC) with grammars of regulated rewriting and show that, if VBC relevant information is distributed over several successive VBC processes and must, in a later stage, be synchronised and co-ordinated, the formal grammar needs to be very powerful with respect to mode of derivation and thus generativ...
Conference Paper
Sepedi (Southern Bantu, S30) does not have grammaticalized focus prosody due to which focused constituents are unambiguously marked by prosodic prominence in one way or another. Nevertheless, prosodic traces of emphasis might still exist. The paper reports on a study that investigates acoustic traces of emphasis in Sepedi and their role for process...
Article
We report on a study that aimed to improve an existing tone label prediction algorithm for Sesotho, an official language of South Africa. Tone is an important prosodic feature of Sesotho, since speakers use tone to distinguish meaning. In order to implement tone in a Text-to-Speech system for Sesotho, a tone modeling algorithm must receive as input...
Conference Paper
We hereby present a technology model for improving the traditional supply chain process on which small enterprises in developing countries rely-upon for stock replenishment. Current procurement processes for small enterprises in emergmg economies are fostered by the lack of direct access to market and social factors influencing these enterprises. S...
Conference Paper
Full-text available
This article discusses the empirical assessments employed on two versions of a Sesotho tone labeling algorithm. This al-gorithm uses linguistically-defined Sesotho tonal rules to pre-dict the tone labels on the syllables of Sesotho words. The two versions differed in the number of tonal rules that they employ as well the lexical categories that the...
Conference Paper
Full-text available
We report on a study that involved the development of a corpus used to verify the performance of two tone labelling algorithms, with one algorithm being an improvement on the other. These algorithms were developed for speech synthesis pur-poses with the aim of improving the perceived naturalness as well as the intelligibility of the speech produced...
Conference Paper
Full-text available
This article reports on a study that involves im-proving a tone label prediction algorithm. Tone is an important prosodic feature for Bantu languages since these languages use it to distinguish meaning. Studies have shown that text-to-speech systems need detailed prosodic models of a language in order to sound natural to native speakers of the lang...
