yea i tried switching voice to us english female street name and i think it shut up even faster. I wonder if it's due to using offline mode on this trip? Anyways my experience thus far is like at least 3 miles of no updates to your path, and it will stop talking. Looks like there are others with the same experience.

It's not critical I guess but it's nice to get a warning after 50clicks of driving straight to wake you up and not miss your exit lol
