Assignee: SONOS, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 16:
17. At least one non-transitory computer-readable medium comprising program instructions that are executable by at least one processor such that a first playback device is configured to:
capture, via at least one microphone, audio into one or more buffers;
analyze the captured audio using a first wake-word detection algorithm configured to detect a first wake word and a second wake-word detection algorithm configured to detect a second wake word, wherein the first wake-word detection algorithm corresponds to a first voice assistant associated with the first wake word, and wherein the second wake-word detection algorithm corresponds to a second voice assistant associated with the second wake word;
when one of the first wake-word detection algorithm and the second wake-word detection algorithm detects, in the captured audio, a wake word corresponding to a particular voice assistant of (a) the first voice assistant or (b) the second voice assistant, transmit, via a network interface over a local area network to a second playback device, a portion of the captured audio corresponding to a voice input;
after transmitting the portion of the captured audio, receive, via the network interface, at least one instruction that is based on the voice input in the portion of the captured audio; and
output audio based on the at least one instruction via one or more amplifiers configured to drive one or more speakers.
