She is a six-year-old child, female, and has a special requirement for her character. Daria starts off the series by being nonverbal, a lot like Cyprus. As the series goes on she starts to do more and more talking but does have periods of time where her voice may sound strained or she will stutter a times. This is important for her character primarily because it is supposed to show that Daria will never be as chatty as other students and may indeed have some points were she will be nonverbal which is why I would like to make sure that throughout the series this is taking note of her character. If you would like to this role is preferred to people who have selective mutism or is someone who is willing to research into it.
