Abstract

The embodiment of the invention discloses an application awakening method and device, a storage medium and electronic equipment. The electronic equipment comprises two microphones and can collect twochannels of audio data and obtain data of background audio played during audio collecting through the two microphones; then the two channels of audio data are subjected to echo cancellation processingaccording to the background audio data so as to cancel self-noise; then the two channels of audio data subjected to echo cancellation are subjected to beam forming processing so as to cancel externalnoise, and the enhanced audio data are obtained; and then text features and voiceprint features of the enhanced audio data are subjected to two-stage verification, when two-stage verification is passed, voice interaction application is awakened, and thus voice interaction between the electronic equipment and a user is achieved. Thus, interference of the self-noise and the external noise can be removed, verification accuracy is guaranteed through two-stage verification, and the purpose of increasing the awakening rate of the voice interaction application is achieved.

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...
