Barr recorded a podcast interview with her longtime friend Rabbi Shmuley Boteach.
She also lamented that some people didn't accept her explanation blaming the sleep drug Ambien for a tweet that likened former Obama adviser Valerie Jarrett to a person created by the Muslim Brotherhood and "Planet of the Apes".
He released the podcast early on Sunday morning, a day after ABC rehired most of the cast of the rebooted show with reported plans to launch a new show, "The Connors", about the popular working class family, but without the original show's namesake. He initially decided not to air the interview.
Barr said she tried to get Ms Jarrett's phone number to apologise to her personally, but couldn't find it. "Because you know, even though I didn't have that in my head it came out that way". "But I didn't mean it the way they're saying I meant it". And that's what's so painful. And that's what I wanted to apologize to her for. "When you hurt people even unwillingly there's no excuse". I've done something egregious and I don't want to be defended.
"She's not really built to be on top of that pyramid, in charge of a lot of people, responsible for them, because she has her own struggles".
After Barr's Twitter rant, Boteach said he "reached out to her and told her that she has a responsibility, in the name of repentance and her commitment to Judaism, to make this right".
"I have black children in my family", she said.
"I'm a lot of things". But I'm not stupid, for God's sake. I would never do that and I didn't do that. I just wouldn't do that. I didn't do that. And if they do think that I am so sorry that I - ya know - it was so unclear and stupid.
She blamed sleeping pills for her tweet - an explanation some people do not accept.
"There's no excuse. I don't excuse it".
"I said to God, 'I am willing to accept whatever consequences this brings because I know I've done wrong". I don't want to get any more racism going from what I did, I don't want that. But they don't ever stop. "And that's really weird too because if I don't speak for myself, who will speak for me". And as a Jew, it's just frightful.
Though "Roseanne" prompted outrage for jokes about characters of color and an episode some critics called Islamophobic, it built up an enormous television audience.
