"I paused a bit too long thinking of a word and it just started responding to my obviously half spoken sentence. Trying again it just became stressful as I had to rush my words out to avoid an annoying response to an unfinished thought."

I'm a native speaker and this was my experience as well. I had better luck manually sending the message with the "push to hold" button.

Same. It cuts off really quick when I'm trying to phrase a complex prompt and I wind up losing my work. So I go to the manual dictation mode, which works really nicely but doesnt give me the hands off mode. I admit, the hands off mode is often better for simpler interactions, but even then, I am frequently cut off mid-prompt.
