What is the correct pronunciation of 'vicis volo'?

Answer 1

It depends what kind of Latin you're speaking...

Ecclesiastical Latin (Church Latin) is pronounced exactly as if it were Italian.

Classical Latin (Roman Latin) is pronounced with slight differences.

Any good Latin dictionary should have a pronunciation guide in the front (or back) which tells you how to pronounce vowel sounds correctly based on the type of Latin you're after, most of the consonant sounds remain the same as English with a few exceptions.

V's are pronounced like W's in Classical Latin.
V's are pronounced like V's in Ecclesiastical Latin.

J's (or rather, I's when used as consonants at the beginning of words,) are pronounced like Y's (or J's) in Classical Latin (and maybe Ecclesiastical Latin too...)

Every letter in Latin is pronounced, there are NEVER silent letters.

If you're looking for a Classical Latin pronunciation try:

Wick-is (Vicis) Woe-low (Volo)

(and the "is" ending in "Wick-is" is like the "is" in "miss").
