  • Botha, GR; Barnard, E (18th Annual Symposium of the Pattern Recognition Association of South Africa (PRASA), 2007-11)
    The authors investigate the factors that determine the performance of text-based language identification, with a particular focus on the 11 official languages of South Africa, using n-gram statistics as features for ...
  • Ndwe, TJ; Dlodlo, ME; Kuun, C; Sharma, Aditi (2008)
    The OpenPhone system is a health information system that is developed to cater for the information needs of caregivers who are caring for HIV/AIDS infected children in Botswana, southern Africa. The system is accessible ...
  • Ngassam, EK; Watson, BW; Kourie, DG (2010-08)
    With this poster, the authors on the denotational semantics of algorithms to suggest an abstraction of a string recognizer. The abstraction provides a unified formalism for representing FA-based string recognizers as an ...
  • Berglund, Martin; Bester, W; van der Merwe, B (Springer Cham, 2018-10)
    Whereas Perl-compatible regular expression matchers typically exhibit some variation of leftmost-greedy semantics, those conforming to the posix standard are prescribed leftmost-longest semantics. However, the posix standard ...
  • Ngassam, EK; Kourie, DG; Watson, BW (Association for Computing Machinery, 2010-10)
    Previous work on implementations of FA-based string recognizers suggested a range of implementation strategies (and therefore, algorithms) aiming at improving their performance for fast string recognition. However, an ...
  • Joubert, LJ; Davel, MH; Barnard, E; Zimu, V (PRASA, 2004-11)
    The need for a bootstrapping approach to the morphological decomposition of words in agglutinative languages such as isiZulu is motivated, and the complexities of such an approach are described. The authors then introduce ...
  • Britz, K; Varzinczak, I (Taylor & Francis, 2018-03)
    We investigate an aspect of defeasibility that has somewhat been overlooked by the nonmonotonic reasoning community, namely that of defeasible modes of reasoning. These aim to formalise defeasibility of the traditional ...
  • Barnard, E; Zarbian, S (2010-05)
    The authors investigate the acoustic realization of tone in continuous utterances in Sepedi (a language in the Southern Bantu family). Human labelers marked each of the 271 syllables in a 15-sentence corpus produced by a ...
  • Govender, Nicolin; Barnard, E; Davel, MH (Interspeech 2005, 2005-09)
    Much theoretical work has been done on the tonal structure of languages in the Bantu family. However, most of these studies are not supported by physical measurements, or even a consistent model for mapping from linguistic ...
  • Louw, A; Davel, M; Barnard, E (4th International Conference of the African Language Association of Southern Africa (ALASA), 2005-07)
    A general-purpose isiZulu text-to-speech (TTS) system was developed, based on the “Multisyn” unit-selection approach supported by the Festival TTS toolkit. The development involved a number of challenges related to the ...
  • Pretorius, L; Marais, Laurette; Berg, A (Springer, 2017-03)
    The Grammatical Framework (GF) not only offers state of the art grammar-based machine translation support between an increasing number of languages through its so-called Resource Grammar Library, but is also fast becoming ...
  • 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 ...
