Abstract  Abstract

The embodiment of the invention discloses a kind of audio signal classification method and apparatus, for classifying to the audio signal of input, this method comprises: according to the sound activity of current audio frame, determine whether to obtain the spectral fluctuations of current audio frame and be stored in spectral fluctuations memory, wherein, the spectral fluctuations indicate the energy fluctuation of the frequency spectrum of audio signalï¼›Whether it is the activity for tapping music or history audio frame according to audio frame, updates the spectral fluctuations stored in spectral fluctuations memoryï¼›According to the statistic of some or all of the spectral fluctuations stored in spectral fluctuations memory valid data, the current audio frame is classified as speech frame or music frames.
