VOICE WAKE-UP METHOD, APPARATUS, AND SYSTEM

Title:

VOICE WAKE-UP METHOD, APPARATUS, AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2021/136037

Kind Code:

A1

Abstract:

A voice wake-up method comprises: receiving multiple voice wake-up messages sent by multiple electronic apparatuses, wherein each of the voice wake-up messages comprises a distance and a wake-up energy value, the distance indicates a distance between the electronic apparatus and a sound source, and the wake-up energy value indicates an energy value of the wake-up word received by the electronic apparatus that sends the voice wake-up message, the wake-up word being generated by the sound source; determining, according to the distance and the wake-up energy value of each of the multiple voice wake-up messages of the multiple electronic apparatuses, whether energy attenuation of the wake-up word generated by the sound source meets an attenuation pattern of acoustic energy radiated by a point sound source; and if the energy attenuation of the wake-up word generated by the sound source does not meet the attenuation pattern of acoustic energy radiated by a point sound source, sending a wake-up prohibiting instruction to the multiple electronic apparatuses. The invention reduces the accidental wake-up rate of apparatuses.
