Will you consider adding a rich variety of high quality (premium) children's voices? You have very few at the moment and they lack range like some of the adult voices have; expressiveness and emotions that can be selected as needed.

Also, will it be possible to add a feature so we can instruct voices to laugh or giggle (since they are practically voice actors)? I haven't seen this in any tool yet, but several of the projects I am working could use that and being able to make this happen will certainly set you apart.
