| 摘要 |
Embodiments of the present invention provide 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. According to the method and the apparatus provided in the embodiments of the present invention, an active voice and an inactive voice can be accurately distinguished. |
