SPEECH/MUSIC DISCRIMINATION FOR RADIO BROADCASTS USING A HYBRID HMM-BAYESIAN NETWORK ARCHITECTURE

Robust Feature Extraction for Speech Recognition Based on Perceptually Motivated MUSIC and CCBC

The Discrete Wavelet Transform (DWT) is a transformation that can be used to analyze the temporal and spectral properties of non-stationary signals like audio. In this paper we describe some applications of the DWT to the problem of extracting in
