L.A.
She sounds like a super Scripter. Is she saying lines or words? do you know where she is getting the line from?
My nephew went through this and will every once in a while he would do this till he was a teen. .. His mom will make a loud clap and then tell him, this is not time to say these words. And then later when he has down time allow him 3 minutes to script.
He was repeating lines from videos or video games, so she made him earn time to each these or play these by having him read.. For as long as her read a book, play quietly, clean his room or played outside, he could then watch a video..
He would flit around so much that the actual time did not always add up to much time..
Let me reassure you, he just graduated from High School and is going to attend college out of state. He has kept up with his therapies and still can call on any of them when he has set backs..
