How many urgent messages do you need to dictate while you're running without your phone?
I'm actually surprised that the watch would work for that without the phone.
It wouldn't have network, so it works offline by itself and saves the urgent message until it regains a network connection?
I'm very thankful that I'm not physically impaired so I'm not forced to rely on the garbage that is the current state of voice commands.
I find it so infuriating to use that I won't do it, but you go for it. Perhaps your training data will improve it enough to eventually arrive at a usable state.
