  • Fuzzy information transmission analysis for continuous speech features 
    Oosthuizen, Dirk Johannes Jacobus; Hanekom, Johannes Jurgens (Acoustical Society of America, 2015-04)
    Feature information transmission analysis (FITA) estimates information transmitted by an acoustic feature by assigning tokens to categories according to the feature under investigation and comparing within-category to ...
  • On the current state of flotation modelling for process control 
    Oosthuizen, Dirk Johannes Jacobus; Craig, Ian Keith; Jämsä-Jounela, Sirkka-Liisa; Sun, Bei (Elsevier, 2017-12)
    Despite significant effort in modelling and simulating flotation circuits, comprehensive model based control and optimisation implementations on industrial circuits remain scarce. In this paper, the factors preventing more ...
  • The relative importance of spectral cues for vowel recognition in severe noise 
    Swanepoel, Rikus; Oosthuizen, Dirk Johannes Jacobus; Hanekom, Johannes Jurgens (Acoustical Society of America, 2012-10)
    The importance of formants and spectral shape was investigated for vowel perception in severe noise. Twelve vowels were synthesized using two different synthesis methods, one where the original spectral detail was ...
