Why does Ayu move her mouth to vibrato?

Really? Her vibratos were kind of dull (and barely were there...)

As for me her vibratos since 2004 are the best vibratos ever, I just love it when she makes them long and exaggerated XD. It gives her voice a great quality.

I think she moves her mouth that it will be more convinient to make it or just a habit. Most of the singers who do vibratos well I saw them doing it.
