(EXPIRED) Lazybird AI Dramatized Narration (Lifetime Deal)
With Lazybird (affiliate link) you can create a full cast audiobook with an AI voice for each character. And you can give the AI character voices instructions on mood, tone and speed. This is the first tool I’ve found with this kind of stage direction.
This is a lifetime deal and the version now will be the worst it will ever be. AI voices get better every year.
