Problems solved by technology

The higher the sensitivity of the device wake-up, the easier it is to trigger more false wake-ups
For example, when the user is chatting with others or watching TV, when the user speaks a word similar to the wake-up word or the TV broadcasts a word similar to the wake-up word, the smart speaker next to it may be awakened by mistake

Abstract

The invention relates to a voice wake-up method. The method comprises the steps: receiving a plurality of voice wake-up messages sent by a plurality of electronic devices, wherein each voice wake-up message comprises a distance and a wake-up energy value, the distance represents the distance between the electronic devices sending the voice wake-up messages and a sound source, and the wake-up energy value represents the energy value of a wake-up word sent by the sound source and received by the electronic devices sending the voice wake-up messages; according to the distances and the wake-up energy values in the plurality of voice wake-up messages of the plurality of electronic devices, determining whether the energy attenuation of the wake-up word emitted by the sound source conforms to theattenuation rule of the sound energy radiated by a point sound source; and when it is determined that the energy attenuation of the wake-up word emitted by the sound source does not accord with the attenuation rule of the sound energy radiated by the point sound source, sending a wake-up forbidding instruction to the plurality of electronic devices. According to the scheme provided by the invention, the false awakening rate of the device can be reduced.

Description

technical field [0001] The present application relates to a voice wake-up method, device and system. Background technique [0002] With the rise of the Internet of Things, smart home has been popularized to a certain extent, and smart home products are more and more widely involved in daily life, and voice interactive products are a typical representative. [0003] At present, most voice interaction products such as smart speakers pursue a high wake-up rate. In order to achieve a high wake-up rate, it is generally necessary to increase the wake-up sensitivity of the device. The higher the sensitivity of the device wakeup, the easier it is to trigger more false wakeups. For example, when the user is chatting with others or watching TV, when the user speaks a word similar to the wake-up word or the TV broadcasts a word similar to the wake-up word, the smart speaker next to it may be awakened by mistake. SUMMARY OF THE INVENTION [0004] The purpose of the present applicat...
