  • Butgereit, LL; Botha, Adèle (IST-Africa 2009 Conference Proceedings, 2009-05)
    With the push to better school results in mathematics, science, and technology related subjects, often language education is moved into the background. In Africa, however, education is often not in the mother tongue of the ...
  • Louw, Johannes A; Davel, M (2006-11)
    Diphone-based speech synthesis has been researched for many years, and some of the most successful concatenative synthesis systems employ diphones. Such systems can produce very intelligible synthetic speech, but tend not ...
  • Sharma Grover, A; Plauche, M; Barnard, E (IEEE, 2009-04)
    This paper presents our work in the design of a SDS for the provision of health information to caregivers of HIV positive children. We specifically address the frequently debated question of input modality in speech systems; ...
  • Sharma Grover, A; Plauche, M; Barnard, E; Kuun, C (2009-04)
    This paper presents the work in the design of a SDS for the provision of health information to caregivers of HIV positive children. The authors specifically address the frequently debated question of input modality in ...
  • Grover, AS; Van Huyssteen, GB; Pretorius, MW (2010-05)
    Human Language technologies (HLT) have been identified as a priority area by South African government to enable its eleven official languages technologically. We present the results of a technology audit for the South ...
  • Govender, Avashna; De Wet, Febe; Tapamo, Jules-Raymond (Technische Universität Berlin, 2015-09)
    Hidden Markov Model (HMM)-based synthesis in combination with speaker adaptation has proven to be an approach that is well-suited for child speech synthesis. This paper describes the development and evaluation of different ...
  • Govender, Avashna; Nouhou, B; De Wet, Febe (IEEE, 2015-11)
    Acquiring large amounts of child speech data is a particularly difficult task. One could therefore consider the possibility to add existing corpora of child speech data to the severely limited resources that are available ...
  • Sefara, Tshephisho J; Mokgonyane, TB; Manamela, MJ; Modipa, TI (IEEE, 2019-08)
    Text-to-speech (TTS) synthesis systems are of benefit towards learning new or foreign languages. These systems are currently available for various major languages but not available for low-resourced languages. Scarcity of ...
  • Butgereit, L (IST-Africa 2009 Conference Proceedings, 2009-05)
    In a world where school books, pencils and paper have to compete with cell phones, IPODs, and MP3 players for pupils' attention, Dr Math entices pupils to practice basic mathematics skills by providing games and competitions ...
  • Moors, Carmen; Wilken, Ilana; Calteaux, Karen V; Gumede, Tebogo (ACM, 2018-09)
    Almost a decade has passed since the first audit on the state of HLT in South Africa was published in 2009. An increase in HLT R&D in South Africa since then, as well as developments in language resource management in the ...
  • Wilken, Ilana; Gumede, Tebogo; Moors, Carmen; Calteaux, Karen V (2018-12)
    Technology audits can play a significant role in surfacing information which can be used by researchers, policymakers and funders alike to build a country’s research and development system of innovation towards increasing ...
  • Modipa, TI; Davel, MH; De Wet, Febe (PRASA 2013 Proceedings, 2013-12)
    Code switching (the process of switching from one language to another during a conversation) is a common phenomenon in multilingual environments. Where a minority and dominant language coincide, code switching from the ...
  • Van Niekerk, DR; Barnard, E (18th Annual Symposium of the Pattern Recognition Association of South Africa (PRASA), 2007-11)
    When doing research into or building systems involving spoken language, one invariably relies on relevantly annotated speech data for analysis and incorporation into such systems. The authors investigate methods and ...
  • Badenhorst, J; Davel, MH; Barnard, E (PRASA, 2012-11)
    We improve on a piece-wise linear model of the trajectories of Mel Frequency Cepstral Coefficients, which are commonly used as features in Automatic Speech Recognition. For this purpose, we have created a very clean ...
  • Marivate, V; Sefara, Tshephisho J (2020-08)
    We study the effect of different approaches to text augmentation. To do this we use three datasets that include social media and formal text in the form of news articles. Our goal is to provide insights for practitioners ...
  • De Waal, A; Barnard, E (PRASA 2010, 2010-11)
    Topic models explain a collection of documents with a small set of distributions over terms. These distributions over terms define the topics. Topic models ignore the structure of documents and use a bag-of-words approach ...
  • Zerbian, S; Barnard, E (Interspeech 2008, 2008-09)
    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 ...
  • Carroll, M; Van Der Merwe, A; Lubbe, S (2009)
    The increasing dependence upon Information systems has resulted in concerns regarding its auditing processes. IS auditing has changed from auditing “around the computer” to auditing through and with the computer. However, ...
  • Harmse, Henriette; Britz, Katarina; Gerber, Aurona J (IOS Press, 2018-09)
    The W3C standardized Semantic Web languages enable users to capture data without a schema in a manner which is intuitive to them. The challenge is that, for the data to be useful, it should be possible to query the data ...
  • Cloete, Jacob PL; Barnard, E; Patel, Hina M (2004-08)
    The authors report on research aimed at gaining an improved understanding of how issues such as language, literacy and previous exposure to technology affect citizens' ability to access government services of different ...
