  • Van Niekerk, DR; Barnard, E (PRASA 2008, 2008-11)
    The quality of corpus-based text-to-speech (TTS) systems depends strongly on the consistency of boundary placements during phonetic alignments. Expert human transcribers use visually represented acoustic cues in order to ...
  • Badenhorst, JAC; Van Niekerk, DR; Barnard, E (2006-11)
    Improving the pronunciations of non-native language learners is an important task in a multilingual society. We focus on segmental aspects of pronunciation, and investigate the design of automated assistants that can be ...
  • Van Niekerk, DR (PRASA, 2011-11)
    The quality of corpus-based text-to-speech (TTS) systems depends on the accuracy of phonetic annotation (alignments) which directly influences the process of acoustic modelling. In this paper the author discusses the rapid ...
  • 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 ...
  • Van Niekerk, DR; Barnard, E (INTERSPEECH 2010, 2010-09)
    The authors present an initial investigation into the acoustic realisation of tone in continuous utterances in Sepedi (a language in the Southern Bantu family). An analytic model for the generation of appropriate pitch ...
  • Van Niekerk, DR; Barnard, E; Schlunz, G (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 ...
  • Van Niekerk, DR; Barnard, E (Elsevier, 2013)
    Pitch is a fundamental acoustic feature of speech and as such needs to be determined during the process of speech synthesis. While a range of communicative functions are attributed to pitch variation in speech of all ...
