I’d like to suggest that support for multiple wakewords could be used for more than just running multiple pipelines.
Commercial voice assistant smart speakers like Google Home or Alexa can cancel/stop alarms, or stop playing music, when the user says “Stop”. Home Assistant’s voice assistant should also have this capability.
What if we were to support multiple wakewords, and use “Stop” as a secondary wakeword that could stop timers, and perhaps send commands to HA to stop playback on media devices?
