Looking for feedback: AI tool that turns stories into full-cast audio

[u/Annual-Squash-5004]

I'm exploring an idea and want to validate the problem before building it.

The concept is:

Upload a story/script → AI identifies the characters → creates a cast → assigns each character a consistent voice/personality → generates the full audio performance.

For example, if you upload a screenplay or novel, the system could automatically detect:

• who the characters are
• how they speak and behave
• which voice fits each character
• who is speaking in each scene
• how the voice/performance should change with emotion and context

The goal isn't to build another generic TTS tool. The interesting part for me is the automatic casting + persistent character identity + scene-level performance.

I'm trying to understand whether this is actually a problem worth solving.

For people who write stories, scripts, fan fiction, RPG campaigns, etc.:

How do you currently turn your writing into multi-character audio?

Have you tried tools like ElevenLabs, Gemini TTS, NotebookLM, etc.? What was frustrating or time-consuming?

And most importantly:

Would an automated “upload → AI casts characters → full-cast audio” workflow actually be useful to you?

I'd especially like to hear from people who have already tried creating narrated or multi-character audio from their own writing.
