Abstract

The present application proposes a voice wake-up method and device. The voice wake-up method includes: acquiring a voice signal to be processed; decoding the voice signal according to a pre-generated search space to obtain a voice recognition result, wherein the search space Including the path where the anti-model is located, the anti-model includes a first anti-model, and the first anti-model is generated according to the word segmentation result training of the wake-up word; when the preceding preset number of words of the speech recognition result is obtained , judging whether the preset number of words contains at least part of the wake-up words; if not, directly determine not to wake up, and end the decoding of the speech signal. The method can reduce false wake-up rate, reduce power consumption, and the like.

Description

technical field [0001] The present application relates to the technical field of voice recognition, in particular to a voice wake-up method and device. Background technique [0002] Voice wake-up technology is a function with the attribute of switch entrance. The user wakes up by voice, and can initiate the operation of human-computer interaction, that is, the machine will only recognize the user's next voice command when it is awakened by the wake-up word spoken by the user. [0003] There are some voice wake-up technologies in related technologies, but they all have certain problems, such as high false wake-up rate, poor noise immunity, full network connection, high power consumption, only one wake-up word, and low wake-up sensitivity. Contents of the invention [0004] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0005] Therefore, an object of the present application is to propose a voice wake-up metho...
