Abstract
Embodiments of the present disclosure provide a voice wake-up method, apparatus, electronic device, and readable storage medium. The method includes: acquiring a deep feature encoded by a voice activity detection (VAD) encoding layer through a VAD decoding layer, the deep feature being extracted from a digital audio signal used for VAD encoding and voice wake-up encoding; determining whether each audio segment in the digital audio signal is a voice according to a probability that each audio frame in the digital audio signal is a voice frame, each audio segment including a plurality of audio frames; and when determining that the audio segment is the voice, indicating, by the VAD decoding layer, to input a deep feature of the audio segment into a voice wake-up decoding layer to perform voice wake-up. The embodiments of the present disclosure improve the accuracy of voice wake-up.
