Is she 'hard of hearing'?
If so, I'm sorry but if she doesn't have either a disease or a natural impediment, there is no reason for her not to enunciate. It almost sounds like she's going for the "little girl" dialect, and thats a bit creepy...
I would think the director of Betrayal would encourage her to "sound out" her lines prior to the first take but maybe the intended bit is vulnerable little girl being naughty for the first time... I half expect her Boss to grab her by the scruff of the neck and tell her to "Woman up"!
She is quite striking but when she starts to speak the allure, for me, is lost. I would really like to hear your thoughts on her choice to speak in "victim" and if you think is as farcical as I , and if you think her choice is just that of a lazy tongue or physical challenge.
Some would say she is just ment to be eye candy and better silent but I think part of a whole desirable package includes the willingness to express oneself my clearly and without verbal distraction. Is it just time for me to clean my ear trumpet?
