Cartoon Animator 5 doesn't come with any text to speech voices nor did Cartoon Animator 4. Both products just use the compatible voices that are found installed on your computer and those included with your Windows OS such as David and Zira. I'm not sure which extra voices you had in CTA4 but it may be that these were older voices and are no longer compatible.
Overall you may find it much easier to use a text to speech service like Replica where can choose from a large library of voices, add your text, and then save as an audio file for use in CTA5.
