The voices

Give every character a voice.

Premium voices can laugh, sigh and react where you tell them to. Express voices are quick and clear for everyday audio. Renea finds the dialogue in your book and gives each character their own voice.

Renea works out who is speaking for you. Anything you haven't cast stays 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 manual, pick the emotions you want and how strong they are. You can do it line by line.
  • ✓
    Direct in the script
    Type a tag like <laugh> or <sigh> where you want it, and the narrator does it right there.

Facial animation

The voice already knows what the face should do.

Any line you make can come with a face. The lips match the words, and the brows, eyes and head move with the feeling in the voice, because they follow how the line was actually read.

Loading the track…

Eight of the 52 face controls in this take, moving live with the video. You get all of them with every line.

Direction, moment by moment

Renea decides the feeling from what you set first, then the tags in your script, then the writing, then the voice itself. The highlighted moments are the ones you asked for.

Face animation

Mouth, eyes, brows and head, all moving with the line. Ready for your own characters.

Captions that match

Subtitles timed to every word, so they line up with the mouth.

A video to share

The line performed by a Renea character, with captions on. Nothing to set up.

Straight into Unreal

Our Unreal plugin puts the animation on your character for you, MetaHumans included.

Production automation

Redo any line, play the whole script through, work in batches and keep every version. It works like a small studio team.

Developer API

Everything on this page also works from your own code, with a cost estimate before you spend. Same credits as the studio.

Developers

Two calls from text to a performing face.

Everything in the studio is an API. Generate voicelines from your game build, your pipeline, or your own product — and get the facial performance back with them.

    Keys you issue yourself
    Make a key in Studio → Developers. It's shown once, we keep only a hash, and revoking it takes effect immediately.
  • ✓
    Safe to retry
    Send an Idempotency-Key and a repeated call returns the original job instead of generating — and charging — twice.
  • ✓
    Price it before you run it
    Estimate endpoints for speech and animation return the credit cost of a job without creating one.

Simple pricing, paid in credits

Plans are priced by how much finished narration you make each month. Retakes are included and making the same take again is free, so you only use credits when you make something new. Pay yearly and you get about two months free.
