Abstract
Disclosed herein are example techniques to support multiple voice assistant services. An example implementation may involve a playback device capturing audio from the one or more microphones into one or more buffers as a sound data stream monitoring the sound data stream for a wake word associated with a specific voice assistant service and monitoring the sound data stream for a wake word associated with the media playback system. The playback device generates a second wake-word event corresponding to a voice input when sound data matching the wake word associated with the media playback system in a portion of the sound data stream is detected. The playback device determines that the voice input includes sound data matching one or more playback commands and sends sound data representing the voice input to a voice assistant associated with the media playback system for processing of the second voice input.
