I am Polish and could pronounce it for you but will try to write it down for native English speaker.
It would be something like: Carol Voy-ti-wa
In Polish language letter "W" is spelled hard like "v" in "volvo" (same e.g. with Polish leader's name Walesa).
Second syllable "ti" sounds hard too like the last syllable in "liberty".
The last syllable, "wa", sounds like in the word "why" but without pronouncing the last "y"
I hope it helped (rather than confused even more :-)
Best regards
Pawel
