It's likely that the cost of hiring a voice actor is significantly lower than that of an on-screen actor. Plus, many voice actors perform multiple roles in the same television program. As an example:
Dragonball Z Kai
Sean Schemmel: Goku and King Kai
Christopher R. Sabat: Piccolo, Vegeta and Yamcha
Also, some voice actors perform on many different series, such as:
Shinji Ikari on "Neon Genesis Evangelion"
Hanataro Yamada on "Bleach"
Akito Tenkawa on "Martian Successor Nadesico"
Shampoo on "Ranma 1/2"
Spike on "My Little Pony: Friendship Is Magic"
Bulma on "Dragonball Z Kai"
Hyatt on "Excel Saga"
Shii on "Puni Puni Poemi"
Ao on "Grrlpower!"
With a CGI character, it should just be a matter of getting the right voice actor.
