Abstract

The invention discloses a method for improving a wake-up effect, and the method comprises the steps: carrying out the first verification through a wake-up model in response to the input audio of a user; and if the first verification is passed, sending the input audio into a semantic recognition module for secondary verification, and judging whether the verification of the wake-up model is valid wake-up or not according to a result of the semantic recognition module. The identification information and / or the semantic information are / is introduced to perform secondary verification on the primary verification result of the wake-up module, and the identification information and / or the semantic information are / is utilized to assist the wake-up decision, so that false wake-up can be reduced.

Description

technical field [0001] The invention belongs to the technical field of awakening, and in particular relates to a method and a device for improving the awakening effect. Background technique [0002] In related technologies, in current voice interaction products, wake-up words are usually set. In actual scenarios, products often need to be able to customize wake-up words, and in some scenarios, the number of customized wake-up words is large. [0003] In the process of implementing this application, the inventor found that the current mainstream wake-up word customization schemes are mainly based on signal and acoustic features, so some schemes may not be able to support non-enumerable wake-up words, and some schemes may have wake-up words The word string problem causes false wake-up. Some solutions also have a limit on the number of wake-up words. If the extended words required by the customer exceed the limit, it cannot be processed. Furthermore, for the false wake-up caus...
