Classification: CPC G  H | IPC G

Claim 13:
14. A system comprising:
one or more processors; and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
receiving a first audio signal generated by a first microphone within an environment;
receiving a second audio signal generated by a second microphone within the environment;
analyzing the first audio signal and the second audio signal to determine that a first participant and a second participant are speaking within the environment;
generating, based at least in part on the first audio signal and the second audio signal:
first audio data that represents first speech of the first participant by attenuating second speech of the second participant from the first audio signal; and
second audio data that represents the second speech of the second participant by attenuating the first speech of the first participant from the second audio signal;

associating the first microphone with the first participant based at least in part on attenuating the second speech from the first audio signal;
associating the second microphone with the second participant based at least in part on attenuating the first speech from the second audio signal;
generating, based at least in part on the first audio data, an audio signature associated with the first participant;
determining a first similarity between the audio signature and a first stored audio signature;
determining that the first similarity is less than a threshold;
determining a second similarity between the audio signature and a second stored audio signature;
determining that the second similarity is greater than or equal to the threshold;
determining, based at least in part on the second similarity, an identifier associated with the second stored audio signature; and

generating a transcript that includes the first speech and the second speech, wherein the first speech is associated with the identifier.
