Abstract

An embodiment of the invention discloses a voice signal separating method, a device thereof, electronic equipment and a storage medium. The method comprises the steps of acquiring the voice signal bymeans of a voice acquisition system, wherein the voice acquisition system comprises at least one pair of double-microphone unit which is composed of two microphones, wherein the position of each double-microphone unit is determined according to the position of a corresponding voice generating point; and separating the acquired voice signal by means of a wave beam forming algorithm, thereby obtaining a target voice source signal. Through the voice signal separating method, the device thereof, the electronic equipment and the storage medium, a target voice source signal can be accurately separated from the voice signal.

Description

technical field [0001] The invention relates to the technical field of signal separation, in particular to a voice signal separation method, device, electronic equipment and storage medium. Background technique [0002] At present, the application of speech recognition technology in the car cockpit is more and more extensive. Voice interaction enables the driver and passengers in the car to access in-car services more naturally and quickly, while also avoiding dangers and accidents that may occur due to the driver's eyes leaving the road. [0003] However, due to the interference of voice commands by people chatting in the car, the existing voice recognition technology cannot accurately determine the location of the voice source. Segments of speech are mixed together, and the user's voice signal cannot be accurately determined from the mixed speech. Contents of the invention [0004] The invention provides a voice signal separation method, device, electronic equipment an...
