LLM & AI Pipeline
Text, audio and video are interpreted by our multimodal AI pipeline. Domain fine-tuning gives the model the vocabulary and context it needs to understand HKSL-related content.
Our technology combines LLM intelligence, HKSL grammar, motion capture and a generative 3D avatar engine. Together, these layers turn everyday digital content into accessible sign-language video.
→ A language-first pipeline for real-world communication.

The LLM learns from text and audio, while the HKSL database, motion references and avatar engine turn that understanding into visual language.

Text, audio and video are interpreted by our multimodal AI pipeline. Domain fine-tuning gives the model the vocabulary and context it needs to understand HKSL-related content.

The language layer reorganises meaning into natural HKSL grammar instead of translating word by word. This preserves sentence structure, context and signing order.

Reference signing data and high-definition video capture the movement, timing and expression needed to communicate the translated sequence clearly.
The HKSL AI engine maps language and motion onto a controllable 3D avatar, producing consistent, reusable signing content at scale.

The final signing video can be delivered through websites, apps, documents and public-service experiences wherever people need access to information.
The database is the bridge between AI understanding and natural signing. It brings together HKSL vocabulary, grammar patterns, 3D model data, high-definition video and curated signing references.
