I've always thought it's pronounced as the 'royce' in the car brand "Rolls
Royce."
That's how I do it anyway, but I could be wrong.
ETA: As far as I can tell by a Wiki search, Rolls
Royce is split between North
America and Germany (by way of Volks Wagen I think), by both car- and plane engine manufacturing. So there could be some
German influence on the pronunciation.
