Abstract : The problem of speech/music discrimination is a challenging research problem which significantly impacts Automatic Speech Recognition (ASR) performance. This paper proposes new features for the Speech/Music discrimination task. We propose to use a decomposition of the audio signal based on wavelets, which allows a good analysis of non stationary signal like speech or music. We compute different energy types in each frequency band obtained from wavelet decomposition. Two class/non-class classifiers are used : one for speech/non-speech, one for music/non-music. On the broadcast test corpus, the proposed wavelet approach gives better results than the MFCC one. For instance, we have a significant relative improvements of the error rate of 39% for the speech/music discrimination task.
