Patent ID: 8392180

Claim:
A method comprising: processing an audio signal with an audio system to identify a first audio source; determining, with the audio system, a non-zero probability of a matching voice print for the first audio source; processing the audio signal with the audio system to identify a second audio source simultaneously present in the audio signal with the first audio source; determining, with the audio system, a non-zero probability of a matching voice print for the second audio source; determining whether the audio system stores an association between the first audio source and a gain for the first audio source; when the audio system stores the association between the first audio source and the gain for the first audio source, reading the gain for the first audio source and a gain for the second audio source, and applying a combination of the gain for the first audio source and the gain for the second audio source to a representation of the audio signal to produce an output audio signal, wherein applying the combination comprises: weighting the gain for the first audio source by the non-zero probability of the matching voice print for the first audio source and the gain for the second audio source by the non-zero probability of the matching voice print for the second audio source; and combining the weighted gain for the first audio source and the weighted gain for the second audio source to produce the combination; and outputting the output audio signal from the audio system.
