Abstract:
A method and an apparatus for detecting audio signals are disclosed. The input audio signal is detected to determine whether it is a background frame. The detected background signal is further detected according to a music characterization value and a decision rule. Therefore, background music can be detected, and the classifying performance of the voice/music classifier is improved.
