US Patent 10462422 Audio selection based on user engagement

In one embodiment, a method includes receiving audio input data from a microphone array of at least two microphones. The audio input data is generated by a first sound source at a first location and a second sound source at a second location. The method also includes calculating a first engagement metric for the first sound source and a second engagement metric for the second sound source. The first engagement metric approximates an interest level of a receiving user for the first sound source, and the second engagement metric approximates an interest level from the receiving user for the second sound source. The method also includes determining that the first engagement metric is greater than the second engagement metric, and processing the audio input data to generate an audio output signal. The audio output signal may amplify sound generated by the first sound source relative to the second sound source.
