Abstract  Abstract

A method of classifying audio signals, comprising: determining (101), based on voice activity of a current audio frame, if a frequency spectrum fluctuation of the current audio frame is to be obtained and the spectrum fluctuation stored frequency in a memory of frequency spectrum fluctuations, where the frequency spectrum fluctuation denotes an energy fluctuation of a frequency spectrum of an audio signal; update (102), depending on whether the audio frame is percussive music, the frequency spectrum fluctuations stored in the frequency spectrum fluctuations memory; and classifying (103) the current audio frame as a voice frame or a music frame according to the statistics of part or all of the effective data of the frequency spectrum fluctuations stored in the frequency spectrum fluctuations memory.
