I have heard the Monaco royals speak. They speak English with an American accent. Also, they speak French like the French.kimebear said:I know that its widely acknowledged that the Monaco royals speak accent free English, but what about their French? Does Monaco have a different dialect of French than France does? If they do, do the royals speak it without an accent as well?? I've heard them speak French, but my own French is so poor I can't tell.
