I dunno...I agree Bujold seems to be a bit stilted, but consider Patrick Stewart for the first half of TNG's first season...
This is a different stiltedness. Picard was this tightwad (almost said "tight-ass") career officer with no family and not many friends. His character was stilted, and intended to be that way.
With Bujold, that's who she actually
"Captain, we are being hailed. That is, if you don't mind...if it isn't too intrusive."
