For an avatar to understand sign language, every single sign needs to be described precisely. Through these annotations, the AI gradually learns to understand German Sign Language – and eventually to perform it itself.

In sign language, every detail matters. To ensure our avatars are always understood clearly, we rely on a multi-stage quality assurance process – from the first recording to the final round of revisions.

We at alangu welcome the 15 principles in the "Ethical Framework on AI and Sign Language" from the European Union of the Deaf (EUD) and take them very seriously.

How is a video with our sign language avatar actually created? Using motion capture, 3D animation, and a great deal of expertise, real signs are transformed into a lively, accessible avatar. A look behind the scenes at modern technology and deaf expertise.

Award-winning DFKI spin-off alangu merges AI research, avatar technology, and community expertise – and is now opening an impact investment round to scale internationally.
