Salve!
I've been taking Latin for a few years--I'm not exactly an expert-- but I do know multiple of the conjugations, declensions, simple conversational Latin and phrases, and the pronunciations and annunciations, so I can likely help you out a bit
To get you started, the vowels are fairly simple. It helps to practice them and learn them well
In Latin...
The English vowel "a" is pronounced "ah" as in "father", unless otherwise marked
The English vowel "e" is pronounced "a" (long a) as in "late", unless otherwise marked
The English vowel "i" is pronounced "ee" as in "need", unless otherwise marked
The English vowel "o" is pronounced "oh", as in "no", no change there, unless otherwise marked
The English vowel "u" is pronounced "oo", as in "new", unless otherwise marked
The Latin alphabet is nearly the same as the English, with multiple differences. An important thing to note is that there is no w in the Latin language. You'll probably find it easier to just read this
pronunciation guide. However, take note that there are two different forms of Latin--Classical, which was spoken by the ancient Romans, and Ecclesiastical, which is what's widely spoken in universities and churches. So depending on which you're planning on taking, the link I gave you was for Ecclesiastical, which is more widely spoken today and easier to study. I can't write much now, but I'll gladly go over some conversational greetings later!
