Abstract

The invention relates to the field of artificial intelligence and particularly relates to pickup methods and device. A method comprises the steps of obtaining user information detected in a pickup range of smart equipment; determining a beamforming direction in the pickup range according to the user information; and controlling the smart equipment to carry out beamforming according to the determined beamforming direction. The beamforming direction is continuously adjusted through utilization of the detected user information, so beamforming directivity is high, requirements of different interaction scenes are satisfied, a pickup effect is improved, and user experience is improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a sound pickup method and device. Background technique [0002] With the development of smart technology, there are many smart devices that can perform voice interaction, such as robots, etc. Smart devices are getting more and more attention and popularity. How to effectively pick up sound with high quality is very necessary. [0003] In the prior art, the sound pickup method of smart devices is mainly to use beamforming (Beamforming) technology to pick up audio signals within the sound pickup range. However, in the center of the prior art, the beamforming direction is fixed. When it is large, the sound suppression in other directions is less, and the surrounding noise is easy to be misidentified. If the beamforming range is set to a small value, although the sound suppression in other directions is strong, when encountering a scene where multiple users face robot interacti...
