Fr. A,
Here's a small lesson on pronunciation.
Doamne miluieşte.
The 'oa' in the word Doamne is a dipthong and pronounced very close to 'wah' in English. Whenever you see a diacritical mark under the letters 't' or 's' (in fact, it will never be found under any other letter), it will be pronounced as 'sh' for the 'ş' and 'ts' (think the last two letters in the word cats) respectively. Also, when the letter 'e' follows the letter 'ce' it's pronounced 'che' as in the first two letters in the word church.
Watch out: in che, chi, ch is not "ch" but "k." Similarly, ghe is hard g.
When you see a diacritical mark above the letter 'a' (it'll look like a smile or a 'v') it affects the pronunciation of that letter as well. 'A' will be pronounced 'uh' (as in the last two letters in the word duh).
So, using our example phrase above, it's pronounced 'Dowahmne mee-luee-eshte' and means "Lord, have mercy".
Also, the letter 'j' is pronounced like the first two letters in the actress' name Zha Zha Gabor found in the phrase Doamne ajuta meaning something like 'God help us' or 'thank God'.
This is pretty much all you need:
