And you can't rely on alternative cues, either. What if it's fixed into a location, such as a car, and the potential speaker is speaking precisely because they're busy and can't unlock the device any other way than by spoken word? Something like, "OK Google, find nearest detour" while in the middle of negotiating a traffic jam in an unknown place could certainly be visualized.
