This is one advantage of a system with a constrained set of commands/grammars, as opposed to the Alexa/Siri model of trying to process all arbitrary text while in active mode. It can simply ignore/discard any invocations which don't match those specific grammars (and no need to wait to confirm that the device is awake). "Computer, turn lights to 50%" -> "turn lights to fifty percent" -> {action: "lights", value: 50} "My new computer has a really beefy graphics card" -> "has a really beefy graphics card" -> {action: null}
