Features of text-to-speech avatars
Enter a script and create a talking avatar
Paste your script and the avatar speaks it back with natural lip-sync and matching expression. The text to video engine turns written words into a finished talking clip in minutes, so you edit by changing the text instead of re-recording a single line.

1,100+ avatars and 300+ AI voices
Choose a presenter from 1,100+ realistic avatars, then pair it with the AI voice generator and its 300+ voices. Match voice to avatar, adjust tone and pacing, and every scene keeps the same face and delivery across the whole video.

Bespoke avatar from a 15-second clip
Create a digital twin of yourself in Avatar V from a single 15-second video, with no eligibility form or studio booking required. The model maintains your face and voice across wide, medium and close-up shots, ensuring your bespoke avatar remains consistent throughout.

Talking avatars in 177+ languages
Type once and generate the same talking avatar in more than 177 languages and dialects, with voice cloning that carries your tone into every version. Regional accents and phoneme-level lip sync ensure every language sounds like a native recording rather than a machine dub.

Direct gestures and long scripts
Direct the avatar in plain English, asking it to look at the camera, lean forwards or remain calm, so its delivery suits the message. A single pass can render up to 30 minutes of continuous talking-head video, maintaining a consistent likeness and voice throughout lengthy scripts.


Traditional training shoots require studios and reshoots for every edit. Turn your script into an avatar-led module, then revise the text and regenerate it whenever a policy or product detail changes, without having to book a crew.

Filming daily short-form content burns hours. Use an AI talking head to post consistent clips for TikTok, Instagram, and X, keeping the same on-screen presenter so your channel builds recognition without you being on camera.

Localizing footage means re-recording for each market. Generate one avatar video, then use the AI video translator to ship it in 177+ languages, so global teams hear the message in their own language.

Screen recordings alone can feel rather flat. Pair a talking avatar with your product walkthrough to explain features step by step, then regenerate the script whenever the interface or pricing changes, keeping every demo up to date.

Recording the same pitch for every prospect does not scale. Script one message, swap in names or details, and send personalized avatar videos at volume, so outreach feels one-to-one without hours on camera.

Having presenters deliver routine updates live ties up on-air talent. Broadcast and media teams can script an avatar presenter to deliver news segments or localised forecasts on demand, updating the video as the story develops without having to restage a shot.
