Abstract

The invention discloses a voice recognition method, device and storage medium. Wherein, the method includes: acquiring a multi-channel audio signal to be identified, the multi-channel audio signal including audio signals collected in multiple directions; acquiring the voiceprint feature of each audio signal in the multi-channel audio signal; Find the target channel audio signal whose voiceprint feature matches the target voiceprint feature of the preset target object; if the target channel audio signal is found in the multi-channel audio signal, extract the target channel audio signal from the multi-channel audio signal . The invention solves the technical problem of low voice recognition accuracy in complex sound environment.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a voice recognition method and device, and a storage medium. Background technique [0002] Reducing the interference that interferes with audio in complex sound environments is an important research direction in audio processing. Methods commonly used in the prior art to reduce audio interference include audio noise reduction, echo cancellation, and multi-tone zone suppression. However, the existing technology can only eliminate the electronic sound emitted by the device and the environmental echo of the microphone, and cannot eliminate the interference of the electronic sound of other devices and the speech interference of other individuals except the user. Individual voices interfere with even carrying out non-user intentions. It cannot distinguish the sound source information in this direction, and will send other sounds besides the user to the voice assistant for voice reco...
