Abstract
Disclosed herein are example techniques to support multiple voice assistant services. An example implementation may involve a playback device continuously capturing, via the at least one microphone, audio into one or more buffers and analyzing the captured audio using a first wake-word detection algorithm and a second wake-word detection algorithm. When one of the first wake-word detection algorithm or the second wake-word detection algorithm detects, in the captured audio, a wake-word corresponding to a particular voice assistant service of (a) the first voice assistant service or (b) the second voice assistant service, the playback device transmits the captured audio to one or more servers associated with the particular voice assistant service. After transmitting the captured audio, the playback device receives, via the network interface, at least one instruction based on the captured audio; and performs one or more actions based on the at least one instruction.
