Locally it comes out as something like 'roo - ray' There is a syllable at the end of 'roo' that is barely discernable 'roo-i'. And the 'ray' is slightly nasal. You really need to be face to face with a man from Wester Ross to get it right.
It's very gratifying to know that the Gallic fails to differentiate between red, white and king. I knew there was a reason why my ancestors learned English.
