YES;

There are plenty of ways to say "yes" in Korean but the correct way is "ye" since that's what it is translated into when you romanize the hangul.

I have also seen people use "nae" and "neh" for it. I don't think it really matters because people will probably know what you mean anyways. 

NO;

Just like "yes" there are a few ways to say "no" in Korean.

The correct way to say it is "Ani-yo" since that is the way it is translated when you romanize the hangul.

The other ways to say it are "Ani-ya" and "Ani"
