Abstract:
Example techniques relate to voice interaction in an environment with a media playback system that is playing back audio content. In an example implementation, while playing back first audio in a given environment at a given loudness: a playback device (a) detects that an event is anticipated in the given environment, the event involving playback of second audio and (b) determines a loudness of background noise in the given environment, the background noise comprising ambient noise in the given environment. The playback device ducks the first audio in proportion to a difference between the given loudness of the first audio and the determined loudness of the background noise and plays back the ducked first audio concurrently with the second audio.

Claim (Index 18):
A method to be performed by a playback device comprising a housing carrying at least a network interface, one or more microphones, an audio stage, one or more speakers, the method comprising:\n while playing back first audio in a given environment at a given loudness via the audio stage and the one or more speakers:\n (a) recording, via the one or more microphones, audio into a buffer; \n (b) detecting, within the recorded audio, a wake word to invoke a voice assistant service; \n (c) in response to detecting the wake word: (i) ducking the first audio while recording, into the buffer, audio representing a voice input to the voice assistant service and (ii) sending, via the network interface to one or more servers of the voice assistant service, the recorded audio in the buffer representing the voice input to the voice assistant service \n (d) receiving, via the network interface from the one or more servers of the voice assistant service in response to the voice input, second audio representing a spoken response to the voice input; and \n in response to receiving the second audio representing the spoken response to the voice input, ducking the first audio while playing back the ducked first audio concurrently with the second audio representing the spoken response to the voice input via the audio stage and the one or more speakers.
