Title:
METHOD AND SYSTEM FOR CANCELLING NOISE IN VOICE COMMUNICATION CONDUCTED BY INTELLIGENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/140070
Kind Code:
A1
Abstract:
The invention relates to a method and system for cancelling noise in voice communication conducted by an intelligent device. The method comprises: acquiring valid audio devices having audio data and located in the same wireless network as an intelligent device; when the number of the valid audio devices reaches a preset number, acquiring digital audio values of the valid audio devices requiring noise cancellation, determining echo cancellation weights for the respective valid audio devices requiring noise cancellation, and multiplying the digital audio values of the respective valid audio devices requiring noise cancellation by the corresponding echo cancellation weights; performing geometric attenuation on the digital audio values of the respective valid audio devices requiring noise cancellation which have been multiplied by the echo cancellation weighs, and taking the attenuated digital audio values as reference echo audio values; and cancelling noise according to the reference echo audio values. When a user uses an intelligent device to conduct voice communication, the invention can reduce interference of environmental and background noise with the voice communication, thereby improving user experience.
