the other marks don't inflect on your voice at all, just the acute accent.
You need to go over some basic grammar things with your professor. Ask him/her about the antecedent, the cedent & there's a third part of the word that I can't remember right now.
Depending on where the accent is, that is how you pronounce the rest of the word.
Most of what you said wasn't that bad, but there's some words you have problems with (longer words) and also things like "ou, oti, ouk, outo, auto," etc. Those you had some definite problems with.
Thanks for responding. so overall how did I sound?
I would give you a 6-7 out of 10. there is definite room for improvement in several areas, but you were understandable. I would say you're very close, but like i said...you need to iron some things out. Listening to Greek all the time is very helpful. being surrounded by it or even immersed in it is even better. Listening to recordings of the psalms, or gospel lessons, etc. I think will help you because then when you see the word you'll already know what it's supposed to sound like.
Beyond that, you should definitely check with your professor about how to pronounce things, especially about rules on accents and all that. That was very helpful for me.
