Adaptive noise cancellation for multiple audio endpoints in a shared space

An apparatus comprising:

• a microphone;
• a loudspeaker;
• a processor in communication with the microphone and the loudspeaker, the processor configured to:
• detect one or more an audio endpoints endpoint co-located with the apparatus at a first location;
• identify a selected audio endpoint of the one or more audio endpoints as a target noise source;
• obtain, from the selected audio endpoint, a loudspeaker reference signal associated with a loudspeaker of the selected audio endpoint;
• remove the loudspeaker reference signal from a microphone signal associated with the microphone to generate an adjusted microphone signal;
• and
• provide the adjusted microphone signal to at least one of a voice user interface (VUI) or a remote audio endpoint, wherein the remote audio endpoint is located remotely from the first location.

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor of a first audio endpoint, cause the processor to:

• detect one or more a second audio endpoints endpoint co-located with the a first audio endpoint at a first location;
• identify a selected audio endpoint of the one or more audio endpoints as a target noise source;
• obtain, from the selected second audio endpoint, a loudspeaker reference signal associated with a loudspeaker of the selected second audio endpoint;
• remove the loudspeaker reference signal from a microphone signal associated with a microphone of the first audio endpoint to generate an adjusted microphone signal;
• and
• provide the adjusted microphone signal from the first audio endpoint to at least one of a voice user interface (VUI) or a second third audio endpoint, wherein the second third audio endpoint is located remotely from the first location.
