Separation method and apparatus for separating far-field and near-field voice and wearable device

Abstract

The present application provides a far-field and near-field voice separation method and apparatus and a wearable device. The method includes: obtaining a near-field beamforming signal and a far-field beamforming signal according to microphone array signal obtained by first microphones in a target scenario and a beamforming algorithm; calculating a near-field voice masking matrix and a far-field voice masking matrix according to the near-field beamforming signal, the far-field beamforming signal and a bone conduction microphone signal; outputting a near-field voice according to the near-field beamforming signal and the near-field voice masking matrix; and outputting a far-field voice according to the far-field beamforming signal and the far-field voice masking matrix. In the present application, the near-field voice and the far-field voice can be effectively separated by fusing the bone conduction microphone signal and the traditional microphone array signal, so that the wearer voice and the far-field voice are obtained.
