Author:Barnard, E; Gouws, E; Wolvaardt, K; Kleynhans, NDate:Nov 2004A number of issues realted to the development of speech-recognition systems with Hidden Markov Models (HMM) are discussed. A set of systematic experiments using the HTK toolkit and the TMIT database are used to elucidate matters such as the ...Read more
Author:Miya, WS; Mpanza, LJ; Marwala, T; Nelwamondo, Fulufhelo VDate:Oct 2008In this paper, a comparison between Extension Neural Network (ENN), Gaussian Mixture Model (GMM) and Hidden Markov model (HMM) is conducted for bushing condition monitoring. The monitoring process is a two-stage implementation of a classification ...Read more
Author:Van Niekerk, DR; Barnard, EDate:Nov 2007When 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 parameters for a baseline ...Read more
Author:Van Niekerk, DR; Barnard, E; Schlunz, Georg IDate:Nov 2009With 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 of relevant speech ...Read more
