Method for separating far-field and near-field voice, apparatus and wearable device

Abstract

The present application provides a method for separating a far-field and near-field voice 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 in a target scenario and a beamforming algorithm; calculating distinguishing features between the near-field beamforming signal and the far-field beamforming signal; obtaining a near-field voice probability of the microphone array signal according to the distinguishing features; and outputting a near-field signal and a far-field signal according to the near-field beamforming signal, the far-field beamforming signal and the near-field voice probability of the microphone array signal. In the embodiment of the present application, a near-field voice and a far-field voice can be effectively separated through the microphone array signal, so that the wearer voice and the far-field voice are obtained.
