If you look on the wear store, apps that create rows of icons on your watch face are very popular. I think that shows that this is a common concern.
Its just too annoying for most people to use.
What voice recognition reminds me of, is a disobedient / distracted little kid, the kind you have to tell everything twice.
I'm not sure my success rate is any better than that typing on my iPhone.
I've noticed UIs always get "needier" over time. Call it VLM's Law. In the old days a dumbphone could be operated tactile in total darkness without looking at it at all. Then smartphones came along which needed occasional glances at the screen to verify the screen and touch screen position/orientation (portrait vs auto-rotated landscape). Now you need to stare continuously at the screen to watch mistakes in the speech to text dictation system as you slowly, tediously, agonizingly argue with a machine.
How clumsy of a UI, like going thru life wearing oven mitts. And VLMs Law is it always gets worse over time. It'll take a lot of work, but we'll find a way to make UIs even more painful.

Maybe it's because I'm from Minnesota and sound like Don LaFontaine, but Google's voice recognition is easily 95% or better for me. Probably closer to 98%, even on spoken sentences for sending emails or texts. When I'm navigating, or trying to call someone, it's closer to 99%.
