Your partner reads the other roles and listens for your cue. Rehearse at your own pace, as many times as you need.
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 for your line and responds to your cue.
Paste text, drop a PDF, or photograph a printed page. AI cleanup helps tidy the formatting. Check the result against your original.
Assign voices to every character but yours. Listen to the samples and choose the age, accent and character that serve the scene.
Speak your lines aloud. Oteria listens for your cue, then plays the next voice. Repeat a line or skip ahead whenever you need.
Performance mode for self-tapes. Hide-my-lines for memorization. Record your performance and listen back as an MP3.

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 a closer word match. The matcher handles contractions and some missed or misheard words.
A dark screen, the orb and dimmed controls to reduce reflections while you film with a separate phone or camera.
Photograph a printed script page and turn it into editable dialogue. Check the words against the original, then cast the voices.
Tidy page numbers, headers and messy formatting for rehearsal. Review the cleaned script before you run it.
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 hearing a scene before the cast meets, Oteria fits around your rehearsal.
A dark screen and dimmed controls keep the focus on your scene. Film with your phone or camera while Oteria reads the other roles.

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. He couldn’t find a tool that suited the performance. So Jack developed Oteria around the performance the film needed: expressive voices, audio direction, and a speech matcher that follows the actor’s lines. He is now sharing it with other actors through private access.
Read the full storyOteria listens through your microphone for the words in your script. When it recognises your line, it plays the next character's cue. You can also advance manually if it mishears you.
Forgiving mode tolerates some missed or misheard words. Strict mode requires a closer word match. Both compare words from the script, not just their meaning, and neither guarantees word-perfect delivery.
Oteria can read the other roles while you film with your phone or camera. Choose a voice, shape its delivery and test a short exchange first. Always follow the audition brief's requirements about readers and AI tools.
