Disclosed in an embodiment of the present invention are a method and device for detecting an audio signal according to a frequency domain energy, the method comprising: receiving an audio signal frame; obtaining a frequency domain energy distribution of the audio signal frame, the frequency domain energy distribution representing an energy distribution characteristic of the audio signal frame in a frequency domain; obtaining, according to the frequency domain distribution of the audio signal frame, a maximum value distribution characteristic of the frequency domain energy distribution derivative of the audio signal frame; taking the audio signal frame and each frame within a preset neighborhood range of the audio signal frame as a frame set, the frame set comprising frames to be detected; and detecting the frames to be detected according to the maximum value distribution characteristic of the frequency domain energy distribution derivative of the frame set. An embodiment of the present invention can realize audio signal detection. |
