I don't think she speaks. The "husband" is claiming she said this before her accident. Her family says that she is responsive through facial expressions and gestures. I doubt they have seen her lately.
Glenn Beck came to Fla a few months ago to seek support for the "parents" position in this case... it seems he has some personal experience with a disabled child, or member of family. He's very adamant about her living.
He spoke about it on his radio program and made quite a big deal about it... VERY Passionate plea to the public. I happen to agree for what it's worth.
