摘要： An electronic device for generating a masking signal is described. The electronic device includes a plurality of microphones and a speaker. The electronic device also includes a processor and executable instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a plurality of audio signals from the plurality of microphones. The electronic device also obtains an ambience signal based on the plurality of audio signals. The electronic device further determines an ambience feature based on the ambience signal. Additionally, the electronic device obtains a voice signal based on the plurality of audio signals. The electronic device also determines a voice feature based on the voice signal. The electronic device additionally generates a masking signal based on the voice feature and the ambience feature. The electronic device further outputs the masking signal using the speaker.

摘要： A method for blind source separation based spatial filtering on an electronic device includes obtaining a first source audio signal and a second source audio signal. The method also includes applying a blind source separation filter set to the first source audio signal and to the second source audio signal to produce a spatially filtered first audio signal and a spatially filtered second audio signal. The method further includes playing the spatially filtered first audio signal over a first speaker to produce an acoustic spatially filtered first audio signal and playing the spatially filtered second audio signal over a second speaker to produce an acoustic spatially filtered second audio signal. The acoustic spatially filtered first audio signal and the acoustic spatially filtered second audio signal produce an isolated acoustic first source audio signal at a first position and an isolated acoustic second source audio signal at a second position.

摘要： Systems, methods, apparatus, and computer-readable media for dereverberation of a multimicrophone signal combine use of a directionally selective processing operation (e.g., beamforming) with an inverse filter trained on a separated reverberation estimate that is obtained using a decorrelation operation (e.g., a blind source separation operation).
