  • Acoustic modelling of cochlear implants 
    Conning, Mariette (University of Pretoria, 2008-08-19)
    High levels of speech recognition have been obtained with cochlear implant users in quiet conditions. In noisy environments, speech recognition deteriorates considerably, especially in speech-like noise. The aim of this ...
  • Acoustic models of cochlear implants 
    Strydom, Trudie (University of Pretoria, 2010)
    Acoustic models are useful tools to increase understanding of cochlear implant perception. Two particular issues in modelling cochlear implant perception were considered in the present study, which aimed at improving ...
  • Objective determination of vowel intelligibility of a cochlear implant model 
    Van Zyl, Jan Louis (University of Pretoria, 2009-06-18)
    The goal of this study was to investigate the methodology in designing a vowel intelligibility model that can objectively predict the outcome of a vowel confusion test performed with normal hearing individuals listening ...
  • Vowel perception in severe noise 
    Swanepoel, Rikus (University of Pretoria, 2010)
    A model that can accurately predict speech recognition for cochlear implant (CI) listeners is essential for the optimal fitting of cochlear implants. By implementing a CI acoustic model that mimics CI speech processing, ...
