AI scene partners that listen to every word, react in real time, and never drop a cue.
You just perform.
You know the work. The hours alone with a script. Reading both parts. Imagining the responses.
Oteria changes that. Paste your script, cast the voices, and rehearse with a partner that’s always ready — one that listens to every word and never misses a cue.
Paste text, drop a PDF, or photograph a printed page. Messy formatting? AI cleanup rewrites it in one click.
Assign AI voices to every character but yours. Warm baritone for the lead. Crisp British for the villain. Fifty voices, every archetype.
Speak your lines aloud. Oteria listens, matches, and cues the next voice instantly. The orb reacts to every word.
Performance mode for self-tapes. Hide-my-lines for memorization. Prose reader for long-form content. And more.

Sarah
Mature, reassuring female
Calm and gentle. Reads kind by default; turns sinister without changing tone.
Liam
Confident young male
Bright and social. The peer, the brother, the best friend.
George
Warm British male
Distinguished and articulate. The professor, the narrator, the gentleman.
Jessica
Playful young female
Bright and expressive. The classmate, the love interest, the confidante.
Chris
Deep authoritative male
Commanding presence. The detective, the general, the voice of reason.
Matilda
Upbeat middle-aged female
Warm and energetic. The mother, the teacher, the professional with heart.
Direct the delivery
DETECTIVE: [softly] I know what you did. SUSPECT: [laughs nervously] You have no idea. DETECTIVE: [whispers] Try me.
Audio direction tags shape how the AI delivers each line — whispers, shouts, laughter, pauses. Your scene partner doesn’t just read. It performs.
Forgiving mode for first reads, strict mode for word-perfect memorization. The matcher adapts to contractions, paraphrases, and natural speech.
Minimal UI, dark screen, just the orb. Built for recording audition tapes — no reflections off your face on camera.
Photograph a printed script page. AI extracts the text, cleans the formatting, and you're ready to rehearse in seconds.
Paste messy text from any source. One click strips stage directions, fixes formatting, and structures it for rehearsal.
Not a script? Paste any passage, pick a voice, and listen. Textbook chapters, articles, your own writing — read aloud beautifully.
Set the beat between lines — tight for rapid-fire, slow for drama. Per-line pause markers let you shape every moment.
Whether you’re taping an audition alone or running a full table read with your cast, Oteria adapts to the way you work.
Performance mode gives you a dark screen, the orb, and nothing else — no reflections, no distractions, just you and the scene. Record your best take with a reader that actually performs.

Browse the voice libraryOur story
Oteria started when Jack, an actor directing a short film, needed to perform opposite an AI therapist — a real speaking character in the scene, not a voiceover. Nothing on the market could pull it off. So he teamed up with his friends at Graybridge Labs and together we built exactly what the film needed. The tool turned out to be something every actor needs.
Read the full storyOteria uses your device microphone and a fuzzy speech matcher that listens to what you say and matches it against your lines in the script. When your line is recognized, it cues the next character's voice automatically.
No. Forgiving mode recognizes paraphrases, contractions, and natural variations. Strict mode is there for when you want word-perfect memorization — you choose the mode that fits where you are in the rehearsal process.
That's exactly what Oteria replaces. Every AI voice is expressive and responsive — whispers, shouts, laughter, pauses. Your scene partner performs the other roles so you can react naturally, even when you're recording alone.
