Indian Sign Language · Inclusive AI
Speech to sign, in near real time.
Our ISL engine turns live speech and text (announcements, alerts, notices and conversations) into accurate Indian Sign Language performed by expressive 3D avatars. Motion is generated dynamically rather than stitched from pre-recorded clips, so it works for unscripted, real-time content at public-infrastructure scale.
What makes it work
- True ISL grammarRe-ordered into ISL's own sentence structure, not word-by-word signing.
- Facial expression & non-manual markersQuestions, negation and emphasis conveyed as Deaf signers expect.
- Dynamic 3D motion synthesisSmooth, natural transitions generated live for any sentence.
- Near real-time renderingOptimised pipeline keeps signing in step with announcements.
- Renders anywhereStation signage, kiosks, web, mobile apps and video calls.

Accessibility at scale
Dynamic generation means any new announcement is signed instantly (no studio recording, no human interpreter bottleneck), making ISL access practical across entire networks of stations, offices and screens. Already deployed for a major Indian railway zone, with ISL translation in under 50 ms on a plain CPU.
Built for two-way conversation.
Alongside speech-to-sign, camera-based ISL recognition converts signing into text and speech, enabling Deaf citizens to converse at counters, kiosks and on video calls.
