Title:
APPARATUS FOR NOISE CANCELING AND METHOD FOR THE SAME
Document Type and Number:
WIPO Patent Application WO/2020/138624
Kind Code:
A1
Abstract:
An embodiment of the present invention provides an apparatus for noise canceling that includes: an input unit configured to receive an input voice signal that is a target of noise canceling; and a processor configured to generate a first voice signal by canceling noise from the input voice signal on the basis of a noise canceling model which is trained using a plurality of reference voice signals through a deep learning algorithm, generate a second voice signal by canceling residual noise from the first voice signal on the basis of statistical analysis, and generate an output voice signal corresponding to the second voice signal.
