Rock-onn, I have changed your thread title (I don't think it's the first time I've had to do this). Titles should include some/all of the words/phrases you are querying.
I don't find either of your sentences particularly natural. They're both grammatically correct but "to speak evil" is not something most of us would use. It sounds like it's from a very old text. Do you simply mean that the person says unpleasant things about you?
