Abstract:
A method for detecting an audio signal and an apparatus, where the method includes determining an input audio signal as a to-be-determined audio signal, determining an enhanced segmental signal-to-noise ratio (SSNR) of the audio signal, where the enhanced SSNR is greater than a reference SSNR, and comparing the enhanced SSNR with a voice activity detection (VAD) decision threshold to determine whether the audio signal is an active signal. Therefore, the method and the apparatus can accurately distinguish an active voice and an inactive voice.

Claim (Index 15):
The non-transitory computer-readable medium according to  claim 13 , wherein the instructions, when executed by the one or more processors, further cause the one or more processors to:\n determine the reference SSNR of the audio signal; and determine the enhanced SSNR according to the reference SSNR of the audio signal.
