Claim 12:
13. A system, comprising:
at least one processor; and
at least one memory comprising instructions that, when executed by the at least one processor, cause the system to:
receive first audio data corresponding to a first representation of an utterance captured by a first microphone of a microphone array;
receive second audio data corresponding to a second representation of the utterance captured by a second microphone of the microphone array;
process the first audio data using a self-attention component to determine first attended data;
process the second audio data using the self-attention component to determine second attended data;
process at least the first attended data and the second attended data using a cross-channel attention component to determine third attended data corresponding to the first microphone, the third attended data representing correlation between the first audio data and at least the second audio data;
process at least the first attended data and the second attended data using the cross-channel attention component to determine fourth attended data corresponding to the second microphone, the fourth attended data representing correlation between the second audio data and at least the first audio data; and
process the third attended data and the fourth attended data to determine output data representing a first acoustic unit of the utterance.
