Abstract

The embodiment of the invention provides a voice wake-up method and a voice interaction method. The voice wake-up method comprises the steps of receiving a voice input signal; determining the similarity of the voice input signal and a preset wake-up voice signal exceeds a first preset threshold or not; if so, sending the voice input signal to a cloud server so as to enable the cloud server to perform voice recognition on the voice input signal and return a recognition result; receiving the recognition result which is returned by the cloud server and corresponds to the voice input signal; determining whether the similarity of the recognition result and the preset wake-up voice signal exceeds a second preset threshold or not, wherein the second preset threshold is greater than the first preset threshold; and if so, waking up a voice interaction function. The voice wake-up method and the voice interaction method provided by the embodiment of the invention can give consideration to the requirements of low power consumption and low error 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...
