Document Type and Number:
WIPO Patent Application WO/2020/238203
Kind Code:
A1
Abstract:
A noise reduction method, a noise reduction apparatus, and a device capable of reducing noise. The method comprising: acquiring a sound input signal received by a target device (S101); performing noise reduction processing on the sound input signal using an external noise signal of the target device to obtain an external target sound signal (S102); and performing noise reduction processing on the external target sound signal using an internal noise signal of the target device to obtain a target sound signal (S103). The present method can not only avoid the influence of the external noise of the device on the accuracy of speech recognition, but also avoid the influence of the internal noise of the device on the accuracy of speech recognition of the device, so that both the effect of noise reduction processing and the intelligence of the device are improved.
