How to Choose
The best voice depends on the book's tone. Ask yourself:
- Is the book serious or playful? Deep voices (George, Adam) for serious. Energetic voices (Charlie) for playful.
- First-person or third-person? First-person benefits from a conversational voice. Third-person works better with a more neutral narrator.
- Single narrator or character voices? Some AI voices handle emotional range better than others.
