Hi...
Cartoon Animator 4 doesn't include ANY text to speech voices. The voices you see are those included with your operating system.
There are some extra voices available but these are generally pretty poor quality and sound very robotic.
For best results you will be better off using a service like Replica which offers really a large range realistic human voices, but instead of downloading them, you just generate an audio file which you can then load into Cartoon Animator. You can check out the quality on the page below.
