Estimating room acoustic properties using microphone arrays

A device comprising:

• a microphone array comprising a plurality of acoustic sensors, wherein the microphone array records a first recording of a speech signal originating from a speaking user;
• and
• a controller configured to:
• receive a second recording of the speech signal recorded at a receiving audio assembly that is remote from the device, wherein the device and the receiving audio assembly are located within a room;
• select one or more audio frames in the first recording and one or more audio frames in the second recording that both occur over a same time period;
• and
• determine a transfer function for the room based in part on the selected one or more audio frames in the first recording and the selected one or more audio frames in the second recording.

A non-transitory computer-readable medium configured to store computer-readable instructions that, when executed by a processor, cause the processor to:

• receive a first recording of a speech signal from an origin audio assembly and a second recording that includes at least a portion of the speech signal, wherein the speech signal originates from a speaking user of the origin audio assembly and the second recording is recorded at a receiving audio assembly operated by a different user and both the origin audio assembly and the receiving audio assembly are located within a room;
• select one or more audio frames in the first recording and one or more audio frames in the second recording that both occur over a same time period;
• and
• determine a transfer function for the room based in part on the selected one or more audio frames in the first recording and the selected one or more audio frames in the second recording.
