Abstract

The present disclosure relates to a voice wake-up method, an apparatus and a computer readable storage medium, and relates to the field of computer technology. The method of the present disclosure includes: beamforming a speech signal in a predetermined plurality of directions to obtain a plurality of beams; input the beam into the pre-trained keyword recognition model to obtain the probability ofthe keyword contained in the beam; according to the probability that the beam contains keywords and the signal quality of the beam, the beam pointing to the sound source direction is determined as the sound source beam; and whether to wake up the system or not is determined according to the characteristic matching results of the sound source beams at a plurality of consecutive times. The invention decouples the beamforming algorithm and the acoustic source localization algorithm without using the existing acoustic source localization method and the speech wake-up process, thereby avoiding theinfluence of the acoustic source localization accuracy on the beamforming algorithm azimuth, thereby improving the wake-up accuracy of the speech system and improving the user experience.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a voice wake-up method, device and computer-readable storage medium. Background technique [0002] With the development of computer technology, the need for information exchange between humans and machines is becoming more and more urgent. Voice, as one of the most natural ways of human interaction, has also become one of the most important ways that people hope to replace the mouse and keyboard to communicate with computers. With the development of smart terminals such as smart homes, smart vehicles, and smart conference systems becoming more and more urgent, the smart voice wake-up system technology as the entrance of smart terminals has received more and more attention. [0003] In the process of voice communication, it will be disturbed by the surrounding environment and the communication medium (such as echo, reverberation and interference sound source, etc.)...
