  • Speech Segmentation Using Bayesian Autoregressive Changepoint Detector 

    Cmejla, R.; Sovka, Pavel (Společnost pro radioelektronické inženýrství, 1998-12)
    This submission is devoted to the study of the Bayesian autoregressive changepoint detector (BCD) and its use for speech segmentation. Results of the detector application to autoregressive signals as well as to real speech ...
  • Study and Application of Silence Model Adaptation for Use in Telephone Speech Recognition System 

    Novotny, J.; Sovka, Pavel; Uhlir, J. (Společnost pro radioelektronické inženýrství, 2004-09)
    This paper addresses the problem of the mismatch between a silence model and background noises which often occurs in a telephone speech recognition system (SRS) application. At first, the use of parallel model combination ...
  • Study of 2-input 2-output Blind Signal Separation by Output Decorrelation 

    Machuca, E.; Sovka, Pavel; Davidek, V. (Společnost pro radioelektronické inženýrství, 1998-12)
    The simulations and experiments representing the initial study of the output decorrelation approach to blind signal separation are presented in this paper. The definition of performance indexes for the evaluation and ...
