Is a digital human the same as an AI avatar?
In short
Not quite. A digital human is a computer-generated likeness that looks like a person, usually photorealistic. The term doesn’t say whether an actor or an AI supplies the words. AI avatar says who is speaking. That is why we call our characters AI avatars. Anyone listening to them should know that an AI is talking.

01Real or not
The AI avatar’s face doesn’t tell you what it is
During a live test, a tester said of the AI avatar, “der ist ja gar nicht echt,” German for “that one isn’t even real.” It was meant as a provocation.
The tester was right all the same, and you can’t tell by looking at it. It is photorealistic. So its name has to say what its face keeps quiet.
02The term
Behind a digital human there may be a person
In film, an actor often plays the digital role. Motion capture transfers their movements and facial expressions to the likeness, and the lines come from the script. At a live show, someone backstage sometimes moves the likeness in real time and lends it their voice.
When a similar likeness answers visitors’ questions at a trade fair booth, an AI may be composing the answers. Standing in front of it, you cannot tell the difference.
03Distinctions
Each term answers a different question
- What does it look like?
Digital human
Describes the look and nothing else. The likeness in a film counts, and so does the one at the trade fair booth.
- Whom does it stand for?
Avatar
An image or a shape that stands in for someone, from a profile picture to a player’s own body in a video game.
- Who is speaking?
AI avatar
An avatar whose words an AI composes. That is what Albert, Vera, Tina and Ken are.
- Whom is it modeled on?
Digital twin
A recreation of a real person, with their face or their voice. If an AI generates it and it could be taken for real, the EU AI Act treats it as a deepfake, and whoever uses it must, as a rule, disclose that.
One face can carry several of these answers. Fraunhofer IAO, a German research institute, has developed a photorealistic AI avatar of Joseph von Fraunhofer, who died in 1826. You can talk to him in real time, and in a May 2026 press release the institute itself calls him a digital twin.
04Our choice
Why we stick with “AI avatar”
Digital human would stress what the audience can already see on the screen. AI avatar names what they can’t, and our characters’ video can carry the term as a permanent caption.
Our characters aren’t digital twins either. Unlike the digital Joseph von Fraunhofer, none of them has a real-life model. Albert, Vera, Tina and Ken are made up.
05For organizers
Three questions tell you more than the term on a proposal
- 01
Is an AI speaking, or a person?
If a person controls the likeness, plan for them like a speaker, with a rehearsal and a seat backstage. If an AI speaks, it needs a briefing on the topic, and someone has to be able to step in.
- 02
How will the likeness be labeled?
If it is modeled on a real person, the deepfake rules may apply. Put in writing who handles the disclosure. Also ask whether the audience will see a notice on screen.
- 03
Who reads along, and who can cut it off?
An AI can get things wrong. Ask whether anyone sees the answer before it is heard, and who operates the stop button on the day.
We also have a person on the technical side during the event, seated next to your sound engineer at the mixing desk and bringing the laptop and the tablet. Unlike at a live show, they don’t lend the AI avatar a voice. The AI composes the words, and the stop button belongs to the moderator.
The AI Act appears here only where it bears on the terms. None of this is legal advice for your event.
