Amazon patents system to pick best audio from multiple devices

1. A system comprising: data processing hardware; and memory in communication with the data processing hardware, the memory storing instructions that when executed on the data processing hardware cause the data processing hardware to: identify a plurality of first computing devices located within a first environment; provide a buffer command to the plurality of first computing devices, wherein each computing device of the plurality of first computing devices is configured to synchronously flush a respective buffer based on the buffer command; obtain, from the plurality of first computing devices, a plurality of first sets of audio data and associated metadata based on the buffer command, wherein each first set of audio data of the plurality of first sets of audio data comprises a respective audio frame for each time period of a plurality of time periods; dynamically select, for each time period of the plurality of time periods, a respective audio frame from the plurality of first sets of audio data based on the associated metadata; determine a second set of audio data based on dynamically selecting, for each time period of the plurality of time periods, the respective audio frame, wherein the second set of audio data comprises at least one respective audio frame obtained from each first computing device of the plurality of first computing devices; generate a continuous audio stream based on the second set of audio data; perform one or more of noise suppression, automatic gain control, or echo cancellation to the continuous audio stream and subsequently generate an output; and route the output to one or more second computing devices located within a second environment.
