Document Type and Number:
WIPO Patent Application WO/2018/233010
Kind Code:
A1
Abstract:
A denoising method and apparatus. The method comprises: receiving a first voice signal picked up by a microphone (S101); if it is detected, with the first voice signal, that a sensor is in an operation state, subtracting an interference noise signal, obtained in advance, from the first voice signal so as to obtain a first voice signal with the interference removed therefrom (S102), wherein the interference noise signal is an interference noise signal generated with regard to the microphone during the operation of the sensor, and the sensor and the microphone are packaged in the same module; and outputting the first voice signal with the interference removed therefrom (S103). By means of implementing the solution provided in the present application, interference in a signal collected by a microphone when the microphone and a sensor in a module operate together is reduced and the small size of the module, packaged with the microphone and sensor, is guaranteed.
