  • Govender, Avashna; De Wet, Febe (IEEE, 2016-12)
    Building synthetic child voices is considered a difficult task due to the challenges associated with data collection. As a result, speaker adaptation in conjunction with Hidden Markov Model (HMM)-based synthesis has become ...
  • Davel, M; Barnard, E (PRASA, 2005-11)
    In this paper the authors describe a new approach to rewrite rule extraction and analysis, using Minimal Representation Graphs. This approach provides a mechanism for obtaining the smallest possible rule set – within a ...
  • Sahraeian, R; Van Compernolle, D; De Wet, Febe (SLTU 2014, 2014-05)
    This paper demonstrates the application of Intrinsic Spectral Analysis (ISA) for low-resource Automatic Speech Recognition (ASR). State-of-the-art speech recognition systems that require large amounts of task specific ...
  • Ndwe, J; Barnard, E; Dlodlo, M; Mashao, D; Kuun, C; Sharma, A (Springer, 2008-09)
    The OpenPhone project aims to design an Interactive Voice Response (IVR) health information system that enables people who are caregivers for HIV/AIDS infected children to access relevant information by using a telephone ...
  • Zulu, PN; Botha, G; Barnard, E (CSIR, 2007)
    Two methods for objectively measuring similarities and dissimilarities between the 11 official languages of South Africa are described. The first concerns the use of n-grams. The confusions between different languages in ...
  • Sharma Grover, A; Calteaux, K; Van Huyssteen, G; Pretorius, M (2010-10)
    South Africa is one of the few countries in the world that boasts a large number of official languages. Due to the efforts of the government and the local research and development (R&D) community all the official languages ...
  • Butgereit, L (African Science Communication Conference, 2006-12)
    Parent Run Science Clubs: A case study at Nooitgedacht 88 Primary School is a presentation case study presentation that will facilitate national, economic and social improvement through human capital development
  • Schlunz, Georg I; Barnard, E; Van Huyssteen, GB (PRASA 2010, 2010-11)
    One of the goals of text-to-speech (TTS) systems is to produce natural-sounding synthesised speech. Towards this end various natural language processing (NLP) tasks are performed to model the prosodic aspects of the TTS ...
  • Schlunz, 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 ...
  • Coetzee, L; Barnard, E (PRASA 2004, 2004-11)
    This paper analyses a number of disabilities, their assistive devices and the associated technologies in order to highlight the role pattern recognition plays in enabling accessibility and improving human computer interaction ...
  • Van Niekerk, DR; Barnard, E; Schlunz, Georg I (PRASA 2009, 2009-11)
    With the increasing prominence and maturity of corpus-based techniques for speech synthesis, the process of system development has in some ways been simplified considerably. However, the dependence on sufficient amounts ...
  • Van Niekerk, DR; Barnard, E (International Speech Communication Association (ISCA), 2009-09)
    The rapid development of concatenative speech synthesis systems in resource scarce languages requires an efficient and accurate solution with regard to automated phonetic alignment. However, in this context corpora are ...
  • Zerbian, S; Barnard, E (NISC, 2008)
    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 ...
  • Peche, M; Davel, MH; Barnard, E (2007-08)
    The authors investigate the addition of a new language, for which limited resources are available, to a phonotactic language identification system. Two classes of approaches are studied: in the first class, only existing ...
  • Govender, Natasha; Barnard, E; Davel, MH (Sabinet Online, 2007-06)
    Although the complexity of prosody is widely recognised, the lack of widely-accepted descriptive standards for prosodic phenomena has meant that prosodic systems for most of the languages of the world have, at best, been ...
  • 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 ...
  • Van Heerden, C; Kleynhans, N; Barnard, E; Davel, M (School of Computer Sciences, Universiti Sains Malaysia, 2010-05)
    We describe several experiments that were conducted to assess the viability of data pooling as a means to improve speech-recognition performance for under-resourced languages. Two groups of closely related languages from ...
  • Peche, M; Davel, M; Barnard, E (2008-11)
    A speech processing system is often required to perform in a different environment than the one for which it was initially developed. In such a case, data from the new environment may be more limited in quantity and of ...
  • Marais, L; Pretorius, L (Southern African Computer Lecturers Association (SACLA), 2015-07)
    Higher education in South Africa is, amongst others, characterised by student language diversity while the language of teaching and learning is mainly English. The University of South Africa has a language policy that is ...
  • Kgampe, M; Davel, MH (PRASA, 2011-11)
    Personal names are often pronounced in very different ways depending on the language background of the speaker. We seek to determine whether some of these pronunciations ‘errors’ are systematic and if so, in which ways. ...
