Document Type and Number:
WIPO Patent Application WO/2021/008000
Kind Code:
A1
Abstract:
Disclosed are a voice wakeup method and apparatus, an electronic device and a storage medium. The method comprises: receiving sound signals collected by a microphone (S110); carrying out fixed beamforming on the sound signals to generate a plurality of beam signals (S120); calculating the signal-to-noise ratio of each beam signal (S130); determining a wakeup direction by means of the signal-to-noise ratios (S140); and carrying out a voice wakeup operation according to a sound signal in the wakeup direction (S150). By means of the wakeup method, a system can accurately determine a wakeup direction in a low signal-to-noise ratio environment, thereby effectively improving the accuracy of voice wakeup.
