Abstract

The present invention relates to the field of artificial intelligence, in particular to a method and device for picking up sound, which acquires user information detected within the sound picking range of an intelligent device; and determines a beamforming direction within the sound picking range according to the user information; According to the determined beamforming direction, the smart device is controlled to perform beamforming. In this way, through the detected user information, the beamforming direction is continuously adjusted, and the beamforming directivity is good, which meets the needs of different interaction scenarios and improves the sound pickup effect. Improved user experience.

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...
