    Abstract: A computing system may determine audio data representing a message that is to be provided to a first user, wherein the first user is associated with at least a first device and a second device. First data corresponding to an audio characteristic of a first physical environment in which the first device is located and second data corresponding to the audio characteristic of a second physical environment in which the second device is located may be determined, wherein the second physical environment is different than the first physical environment and the second data is different than the first data. The computing system may determine, based at least in part on the first data and the second data, that the second physical environment is better suited for outputting audio corresponding to the message than the first physical environment, and may send the audio data to the second device via a network to cause the second device to output the audio based at least in part on the second physical environment being better suited for outputting the audio than the first physical environment.

    Abstract: A computer-implemented method involves receiving a request corresponding to input provided by a user and generating first data associated with a response to the request. Second data associated with a proximity of the user to the first computing device may be received from the first computing device, and third data associated with a proximity of the user to the second computing device may be received from the second computing device. Based at least on the second data and the third data, it may be determined that the user is closer to the first computing device than to the second computing device. Based at least in part on the user being closer to the first computing device than to the second computing device, it may be determined that the response is to be sent to the first computing device.

    Abstract: The systems, devices, and processes described herein may asynchronously transfer audio signals from a voice-controlled device to a remote device. The audio signals may correspond to sound that is captured by multiple microphones of the voice-controlled device, which may then process the audio signals. The audio signals may also be transferred to the remote device for processing. Moreover, a determination of whether the voice-controlled device or the remote device is to process the audio signals may be based at least in part on the bandwidth of a network communicatively coupled to the voice-controlled device. The voice-controlled device may also cache and log the audio signals, and then asynchronously stream the audio signals to the remote device after the audio signals are initially processed, which may be based on the bandwidth of the network. The remote device may utilize the unprocessed audio signals to improve subsequent processing of audio signals.
