She's only 12 so she should have a younger/higher pitched voice print.

Sukie is actually a mute character so she doesn't have any spoken lines, but I need someone that is able to convey emotion through reactionary sounds-- like hums and gasps.

Sukie has had a very tough life and doesn't trust people because of it. She's very shy and lonely. As an orphan, she wants nothing more than to find a family to call her own.
