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; and one or more processors configured to perform a first noise cancellation using as input the received input voice signal to generate a first voice signal by cancelling noise from the input voice signal using a noise canceling model which is trained using a plurality of reference voice signals, perform a second noise cancellation using as input the first voice signal generated by the noise canceling model to generate a second voice signal in which residual noise is canceled from the first voice signal using statistical analysis, and generate an output voice signal comprising an encoding of the second voice signal.
