Abstract  Abstract

An embodiment of the invention discloses an audio signal classification method and device, which are used for carry out classification on input audio signals. The method comprises the following steps: according to sound activity of a current audio frame, determining whether obtaining spectrum fluctuation of the current audio frame and storing the spectrum fluctuation to a spectrum fluctuation storage device, wherein the spectrum fluctuation represents energy fluctuation of frequency spectrum of the audio signals; according to the result of whether the audio frame is a percussion music or the activity of a history audio frame, updating the spectrum fluctuation stored in the spectrum fluctuation storage device; and according to statistics of a part of or all of effective data of the spectrum fluctuation stored in the spectrum fluctuation storage device, classifying the current audio frame into a speech frame or a music frame.
