Did anyone else recently notice that Annie got one of her voice files back?

She has this new squeal that I'd never heard before two or three days ago, but when I looked it up, it turns out that she used to have it, and then it was gone for a long time. Now it's back! Anyone else notice? It was part of her old voice where she had a much higher pitch in her voice. She says it when she Q's I think...

Listen between 0:11 - 0:16 in that video. It's one of those noises that she makes again now.
