The present disclosure relates to a speech enhancement apparatus, and specifically, to a method and apparatus for a target exaggeration for deep learning-based speech enhancement. According to an embodiment of the present disclosure, the apparatus for a target exaggeration for deep learning-based speech enhancement can preserve a speech signal from a noisy speech signal and can perform speech enhancement for removing a noise signal.

Disclosed are methods of encoding and decoding an audio signal using side information, and an encoder and a decoder for performing the methods. The method of encoding an audio signal using side information includes identifying an input signal, the input signal being an original audio signal, extracting side information from the input signal using a learning model trained to extract side information from a feature vector of the input signal, encoding the input signal, and generating a bitstream by combining the encoded input signal and the side information.

A residual echo estimator estimates a residual echo of a microphone signal input to a microphone as a reference signal is output through a speaker. The residual echo estimator estimates a magnitude of a residual echo of the reference signal at a current frame by using a magnitude of the linear echo of the reference signal at the current frame and a magnitude of the linear echo of the reference signal at a past frame, and updates weights to be applied to the magnitudes of the linear echo.
