Abstract  Abstract

Audio signal classification method. The method comprises: determining (101), according to voice activity of a current audio frame, obtaining a frequency spectral variation of the current audio frame and storing it in a frequency spectrum variation memory; Updating (102) frequency spectral fluctuations stored in the frequency spectral fluctuation memory, depending on whether the audio frame is percussive music or according to activity of past audio frames; And classifying (103) the current audio frame into a voice frame or a music frame according to statistics of some or all of the valid data of the frequency spectrum variations stored in the frequency spectrum variation memory. An audio signal classification apparatus is further provided.
