AI Performance Studio

Give your script a voice — and a face.

Audiobooks, podcasts, video scripts, game voicelines. Renea AI performs your text with voices you direct line by line, then hands back the facial animation to match — mastered, ready to ship, and callable from your own code.

The studio

From a raw script to a finished release.

Narration, casting, direction, facial animation, mastering, QA and publishing — the whole job in one place, not five tools stitched together.

Import any script

EPUB, PDF, DOCX, Markdown, or pasted text. Renea AI auto-detects chapters, scenes, and titles, so a long document's structure carries straight into the audio — then narrates the whole thing unattended and emails you when it's done.

Narrators that perform

Expressive neural voices that breathe and pause. Premium narrators even act out inline tags like <laugh> and <sigh> — not flat text-to-speech. Preview every voice free.

Cast every character

Renea AI finds the dialogue, works out who's speaking, and performs each character in a voice you pick — narrator in one, the hero in another, the villain in a third. A cast recording from one manuscript.

One-tap studio mastering

Finish with professional presets — Audiobook (ACX), Podcast, Warm — or build your own chain: compressor, EQ, gain and reverb, baked into the final audio.

Guaranteed Audible-ready

Turn on ACX mode and every chapter is mastered to Audible's exact spec — peak, loudness, and noise floor — with a pass/fail report so your upload is never rejected.

Say every name right

Renea AI scans your manuscript and flags the names it might trip on. Add a pronunciation once, and every voice says it the same way across the whole book.

Proof-listen, not re-listen

A QA pass flags the passages worth a second listen — a rushed line, a dropped word, a tricky name — so you check a shortlist instead of the whole book.

Export for any platform

One click gives you the right file for each store: a chaptered M4B for Audible and Apple Books, CBR MP3 for ACX, lossless WAV for distributors, or a single track for YouTube.

Promote it in a tap

Turn any passage into a shareable audiogram — cover art, an animated waveform, and your caption — sized for Reels, TikTok, or a feed post.

Multi-voice casting

Give every character their own voice.

Renea AI reads the dialogue, works out who's speaking, and performs each character in a voice you choose. The narration stays in your narrator's voice; everyone else comes alive. A full cast recording — from a single manuscript, no second narrator required.

  • Automatic dialogue detection and speaker attribution
  • A distinct voice and delivery for each character
  • Narration and un-cast lines stay with your narrator

Emotional direction

Don't just generate the line. Direct it.

The same sentence can land a dozen ways. Renea gives you the controls a director would reach for — the emotion, how hard it lands, the mood of the whole take — and applies them to the voice and the face together.

  • Let it read the room
    Leave direction on auto and Renea works the emotion out from the writing and the read itself, then performs it.
  • Or call it yourself
    Switch to a manual mix, dial the emotions you want, and set how hard they land. Per line, not per project.
  • Direct in the script
    Tags like <laugh> and <sigh> are performed where you put them, and they override whatever the text implied.

Facial animation

The voice already knows what the face should do.

Every line you generate can come back as a facial performance — lip sync that matches the words, and a face that carries the emotion behind them. Not a mouth flapping on a loop: brows, cheeks, eyes and head, moving because of how the line was read.

Performance track
52 ARKit channels30 fpsEmotion-conditioned

Loading the track…

Eight of the 52 channels in this take's track, read live off the frame that's playing. The full track ships as JSON.

Direction, moment by moment

Renea reads the direction from four places, in order: what you set, the tags in your script, the writing itself, then the read. Every track tells you which one won — highlighted spans are ones you or your script asked for.

A blendshape track

52 ARKit channels plus head and neck rotation, per frame, at the frame rate you ask for.

Word-timed captions

SRT and WebVTT straight from the same alignment that drives the mouth.

A share-ready video

The performance rendered on a Renea avatar with captions burned in — nothing to set up.

Into your engine

ARKit is the channel set MetaHuman and face-capture tools already speak; our Unreal plugin drops the track onto a character.
