Abstract

The present invention provides a voice wake-up method and a voice interaction device. The method includes the following steps that: voice input signals are received; the first similarity of the voice input signals and preset wake-up voice signals is determined according to a first acoustic model, and whether the first similarity exceeds a first preset threshold value is judged; and if the first similarity exceeds the first preset threshold value, second similarity between the speech input signals and the preset wake-up voice signals is determined according to a second acoustic model, and whether the second similarity exceeds a second preset threshold value is judged, if the second similarity exceeds the second preset threshold value, a voice interaction function is awaken, wherein the accuracy of the second acoustic model is higher than the accuracy of the first acoustic model. The voice wake-up method and the voice interaction device provided by the embodiment of the invention have the advantages of low power consumption and low wrong wake-up rate.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of voice recognition, and in particular, to a voice wake-up method and a voice interaction device. Background technique [0002] With the rapid development of speech recognition technology, the application scenarios of voice interaction are becoming more and more common. Smart TVs, smart cars, smart homes, and smart robots are the main application scenarios of voice interaction applications. As it gets higher and higher, the distance of man-machine voice dialogue is not limited to close talk (within 50cm). Now through multi-microphone technology, it has been able to realize long-distance voice interaction within 3-5 meters. [0003] At the same time, there is still a problem in long-distance voice interaction, that is, when to trigger voice radio and start recognition. There are two current technical solutions. One is to use a low-power chip to collect sound through the microphone arr...
