Abstract: Example techniques relate to local voice control in a media playback system. A satellite device (e.g., a playback device or microcontroller unit) may be configured to recognize a local set of keywords in voice inputs including context specific keywords (e.g., for controlling an associated smart device) as well as keywords corresponding to a subset of media playback commands for controlling playback devices in the media playback system. The satellite device may fall back to a hub device (e.g., a playback device) configured to recognize a more extensive set of keywords. In some examples, either device may fall back to the cloud for processing of other voice inputs.

Abstract: A first network microphone device (NMD) is configured to (i) detect a wake word included in a voice input, (ii) transmit, to a second NMD, an indication that the first NMD detected the wake word, (iii) receive, from the second NMD, an indication that the second NMD detected the wake word, (iv) begin processing the voice input to determine a response, (v), determine a delay time for transmitting an arbitration message indicating that the first NMD will respond to the voice input, and (a) if the first NMD receives, during the delay time, an arbitration message indicating that the second NMD will respond, refrain from transmitting the arbitration message or (b) if the first NMD does not receive, during the delay time, an arbitration message indicating that the second NMD will respond, (i) transmit the arbitration message to the second NMD, and (ii) respond to the voice input.
