Here's a breakdown of the pronunciation:
* Roo: Like the English word "roo" but with a slightly more open "oo" sound.
* DOHLF: The "D" is soft, almost like a "d" in the English word "the". The "L" is pronounced clearly, and the "F" has a similar sound to the English "f".
The accent on the last syllable (the "e") is not pronounced.
