Transforming Railway Announcements into Indian Sign Language (ISL) for Deaf and Hard-of-Hearing Passengers
Real-Time ISL Translation
AI converts audio announcements to sign language video instantly
Millions of passengers are excluded from critical railway announcements every day
Audio-only announcements at railway stations completely exclude Deaf and Hard-of-Hearing (DHH) passengers from receiving critical travel information.
India has over 63 million people with hearing disabilities – one of the largest DHH populations in the world, with limited accessibility infrastructure.
Missing announcements about platform changes, delays, or emergencies can lead to missed trains, confusion, and serious safety risks.
The Rights of Persons with Disabilities Act, 2016 mandates accessible public services. Railways must comply with accessibility standards.
"Every announcement that goes unheard is an opportunity for inclusion that's missed."
An AI-powered system that converts railway announcements into Indian Sign Language in real-time
The Indian Sign Language Public Announcement (ISL-PA) system is an innovative AI-powered solution designed to make railway station announcements accessible to Deaf and Hard-of-Hearing passengers.
Using advanced speech recognition, natural language processing, and AI avatar technology, the system automatically translates audio announcements into accurate ISL videos displayed on station screens.
The entire translation process happens in under 2 seconds, ensuring passengers receive ISL interpretation simultaneously with the audio announcement.
