Abstract

The embodiment of the present application discloses an application wake-up method, device, storage medium and electronic device, wherein the electronic device includes two microphones, which can collect two channels of audio data through the two microphones, and obtain the audio data played during the audio collection period. background audio data; then, according to the background audio data, perform echo cancellation processing on the two channels of audio data to eliminate self-noise; then, perform beamforming processing on the two channels of echo-cancelled audio data to eliminate external noise and obtain enhanced audio data; then, perform two-level verification on the text features and voiceprint features of the enhanced audio data, and wake up the voice interaction application when the two-level verification passes, so as to realize the voice interaction between the electronic device and the user. Therefore, the present application can eliminate the interference of self-noise and external noise, and use two-level verification to ensure verification accuracy, so as to achieve the purpose of improving the wake-up rate of voice interactive applications.

Description

technical field [0001] The present application relates to the technical field of voice processing, in particular to an application wake-up method, device, storage medium and electronic equipment. Background technique [0002] At present, with the development of voice recognition technology, electronic devices (such as mobile phones, tablet computers, etc.) can interact with users through voice interaction applications. For example, users can say "I want to listen to ** songs", and the voice After the interactive application recognizes the user's voice and recognizes the user's intention to listen to the *song, it plays the *song. It can be understood that the premise of the voice interaction between the user and the electronic device is to wake up the voice interaction application. However, in the actual use environment, there are often various noises, so that the wakeup rate of the voice interaction application is low. Contents of the invention [0003] Embodiments of th...
