I don't speak Russian, but when the remains of the Czar were DNA matched and reburied in St. Petersburg, Time magazine's article mentioned that the descendants of the Romanovs who came to the church spoke a style of Russian not typically heard-- a court style of Russian that is heavily infused with French pronunciation and sounds. The writer of the article said it was very elegant sounding. I guess the equivalent for English speakers would be Queen Elizabeth II's way of speaking, but yeah -- I know this analogy doesn't *completely work*.
