1. A method of acoustic echo cancellation (AEC), the method performed by at least one processor and comprising:
receiving an audio signal obtained from a microphone;
inputting the audio signal into a neural-network based AEC model, wherein the neural-network based AEC model is trained using a training audio signal; and
outputting an AEC signal from the neural-network based AEC model in which AEC is applied to the audio signal, wherein the AEC signal is a version of the audio signal in which acoustic echo noise of the audio signal is suppressed and target audio of the audio signal is sustained, and wherein the neural-network based AEC model outputs the AEC signal based on estimating a far-end non-linear distortion, a transition factor, and a non-linear transition function.
