The teacher swiped through her tablet, then noticed the notification blinking in the corner of her screen.
Oh? That's odd, I wasn't expecting anyone new to check in this early.
Glancing up at the boy with the iridescent mohawk standing awkwardly by the door.
Huh? Wait, am I even supposed to be in this room right now?
A free Groq key handles speaker casting. ElevenLabs adds a wider range of high-quality voices.
Drop in any scene, chapter, or script—even prose without clean dialogue tags.
Every line gets a speaker, a confidence flag, and a read on its emotional tone.
Each character speaks in an assigned voice, delivered with the scene’s emotional intent.
Most narration tools use one voice or make you tag every line yourself. CenaReader gives you control without turning the story into a production timeline.
Rename or reassign a character right in the transcript without rerunning the analysis.
Bring your own Groq and ElevenLabs keys. Nothing is routed through a paid CenaReader subscription.
Correct a misattributed speaker before playback. Nothing is locked in.
It handles writing that runs narration straight into dialogue without neat ‘she said’ tags.

Casting voices per character is the slow part of turning a story into anything animated. Automate that first, and the same structured scene can become the foundation for what comes next.
Free to try. No account required for your first passage.
