How to make an AI avatar (a consistent character that speaks)
In short
An AI avatar is a presenter you never have to film — a consistent face that speaks your script to camera. Here is how to make an AI avatar, step by step.
An AI avatar is a presenter you never have to film: a consistent character that looks into the camera and speaks your script, with a natural voice and matching lip-sync. Use one as the face of a channel, a brand spokesperson or a talking-head ad. Here is how to make an AI avatar, step by step.
1. Choose or upload a face
Pick a character from the avatar library — different looks and vibes — or upload your own. This is the face people will see every time, so choose one that fits your brand or channel and stick with it for consistency.
2. Write the script
Write what the avatar should say, spoken-style: short sentences, one clear idea per line, a hook up front. Keep it to the length you need — a tight 15–30 seconds carries a social clip better than a rambling minute.
3. Pick the voice and language
Choose the voice and language the avatar speaks in. The voice becomes part of the character, so match its tone to the face and the message, and keep it the same across videos so the avatar feels like one person.
4. Generate the talking video
Generate; the avatar delivers the script to camera with natural movement and lip-sync, ready in minutes. Reuse the same face and voice for every video so your presenter stays recognisable across a whole series.
Summary
An AI avatar is now a face, a script and a voice — a consistent presenter with no camera, studio or on-screen talent. In FATTLY you pick the avatar, write the script and generate the talking video.
Frequently asked questions
Can I reuse the same avatar across videos?
Yes — that is the point. Keep the same face and voice and your presenter stays consistent across a whole series, so viewers recognise your channel or brand.
Do I need to film or show my own face?
No. You choose a character from the library or upload one; the movement, voice and lip-sync are generated. Nothing is filmed.
What can I use an AI avatar for?
A faceless channel presenter, a brand spokesperson, talking-head ads, explainers, product intros — anywhere you want a consistent face delivering a script without a shoot.
