  • Van't Wout, Magdalena C; Pieterse, Heloise; Ball, Shaun V (IEEE, 2019-10)
    An overview of the literature on military-related stress confirms that stress remains part of the deployed soldier’s life, whether it relates to concerns about his family back home, the nature of the military environment, ...
  • Mokgonyane, TB; Sefara, Tshephisho J; Manamela, MJ; Modipa, TI (IEEE, 2019-08)
    Speaker recognition is a technique that automatically identifies a speaker from a recording of their speech utterance. Speaker recognition technologies are taking a new direction due to rapid progress in artificial ...
  • 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 ...
  • Badenhorst, Jacob AC; De Wet, Febe (MDPI, 2019-08)
    When the National Centre for Human Language Technology (NCHLT) Speech corpus was released, it created various opportunities for speech technology development in the 11 official, but critically under-resourced, languages ...
  • Mokgonyane, TB; Sefara, Tshephisho J; Modipa, Thipe I; Mogale, MM; Manamela, MJ; Manamela, PJ (IEEE, 2019-01)
    Speaker recognition is a technique used to automatically recognize a speaker from a recording of their voice or speech utterance. Speaker recognition technology has improved over recent years and has become inexpensive and ...
  • Schlünz, Georg I; Dlamini, Nkosikhona; Tshoane, Alfred; Ramunyisi, Ndivhuwo S (IEEE, 2017-11)
    Text normalisation in text-to-speech synthesis comprises the segmentation and classification of the incoming text and the subsequent expansion of non-standard words into their standard word, spoken forms. We present a ...
  • Schlünz, Georg I; Dlamini, Nkosikhona; Kruger, Rynhardt P (Curran Associates, Inc, 2016-09)
    Text-to-speech synthesis can be an empowering communication tool in the hands of the print-disabled or augmentative and alternative communication user. In an effort to improve the naturalness of synthesised speech – and ...
  • Tönsing, KM; Van Niekerk, K; Schlünz, Georg I; Wilken, Ilana (Elsevier, 2018-06)
    BACKGROUND: In South Africa, many persons in need of augmentative and alternative communication (AAC) come from multilingual backgrounds. There is as yet a limited evidence base (locally and internationally) for the provision ...
  • Tönsing, KM; Van Niekerk, K; Schlünz, Georg I; Wilken, Ilana (AOSIS, 2019-04)
    Background: Augmentative and alternative communication (AAC) can assist persons with complex communication needs to communicate competently with a variety of communication partners in a variety of contexts. However, AAC ...
  • Casini, G; Straccia, U; Meyer, Thomas A (Elsevier, 2018-09)
    Description Logics (DLs) under Rational Closure (RC) is a well-known framework for non-monotonic reasoning in DLs. In this paper, we address the concept subsumption decision problem under RC for nominal safe ELO , a notable ...
  • Louw, Johannes A; Moodley, Avashlin (2016-12)
    In this paper we present a new cascading conditional random field based phrase break model for text-to-speech systems, trained on the speaker specific acoustic data that the text-to-speech voices are trained on. The training ...
  • Daykin, JW; Groult, R; Guesnet, G; Lecroq, T; Lefebvre, A; Léonard, L; Mouchard, L; Prieur-Gaston, E; Watson, Bruce (Prague Stringology Club, 2018-08)
    Online exact string matching consists in locating all the occurrences of a pattern in a text where only the pattern can be preprocessed. Classical online exact string matching algorithms scan the text from start to end ...
  • 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 ...
  • Badenhorst, Jacob AC; Martinus, Laura; De Wet, Febe (2019-01)
    Since the release of the National Centre for Human Language Technology (NCHLT) Speech corpus, very few additional resources for automatic speech recognition (ASR) system development have been created for South Africa’s ...
  • Casini, G; Meyer, T; Varzinczak, I (2018-10)
    In this paper we present what we believe to be the first systematic approach for extending the framework for defeasible entailment first presented by Kraus, Lehmann, and Magidor—the so-called KLM approach. Drawing on the ...
  • Leenen, Louise; Meyer, T (IGI Global, 2018-01)
    The Governments, military forces and other organisations responsible for cybersecurity deal with vast amounts of data that has to be understood in order to lead to intelligent decision making. Due to the vast amounts of ...
  • Botha, L; Meyer, Thomas; Penaloza, R (2018-10)
    Description Logics (DLs) that support uncertainty are not as well studied as their crisp alternatives, thereby limiting their use in real world domains. The Bayesian DL BEL and its extensions have been introduced to deal ...
  • Ramunyisi, Ndivhuwo S; Badenhorst, Jacob AC; Moors, Carmen; Gumede, Tebogo (ACM, 2018-09)
    Speech-driven command and control is increasingly gaining momentum in the world around us. Using human speech to control appliances in trendy living spaces allows a user to control many appliances remotely. This paper ...
  • Britz, K; Varzinczak, I (Springer, 2018-06)
    Modal accounts of normality in non-monotonic reasoning traditionally have an underlying semantics based on a notion of preference amongst worlds. In this paper, we motivate and investigate an alternative semantics, based ...
  • 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 ...
