Abstract
The present application discloses an automatic gain control method and apparatus for a voice interaction system, a system, and a computer-readable storage medium. The method comprises: receiving a voice signal; dividing the received voice signal into a plurality of sound signals of different sound sources by blind source separation; invoking a pre-trained wake-up word detection model to perform wake-up word detection on the sound signals of different sound sources respectively, to determine a sound signal in which a wake-up word is detected; calculating, based on the sound signal in which the wake-up word is detected, a gain required for automatic gain control of the voice interaction system, to adjust a volume of picked-up audio data within a preset range.
