Abstract: A speech enhancement method includes steps as follows. Subband decomposition processing is performed on at least two paths of target speech to obtain amplitude spectrums and phase spectrums of the at least two paths of target speech, where the at least two paths of target speech include: target mixed speech and target interference speech; a prediction probability of the target mixed speech including target clean speech in a feature domain is determined according to the amplitude spectrums of the at least two paths of target speech; and subband synthesis processing is performed according to the prediction probability and the amplitude spectrums and the phase spectrums of the at least two paths of target speech to obtain the target clean speech in the target mixed speech.
