Hello Nahla -
The Avatars themselves & their appearance is completely independent of the voice that you assign to them.
As we all know - it is impossible to know what language/ accent a person (or animal/robot/unicorn :-)) speaks just by their appearance. In the same way, our Voki characters can speak with any voice you choose to assign to them.
Hope this helps,
The Voki Team
