Speak with
silent hands.
Hear with eyes.
SignSetu turns Indian Sign Language into spoken words — and voice into signs — in real time. Build empathy, foster awareness, and connect inclusively with the Deaf and hard-of-hearing community.
Why ISL accessibility matters more than ever.
Global Isolation
Most digital content lacks sign language support, leaving millions of ISL users isolated from critical information.
63 Million+ Voices
In India alone, over 63 million people are deaf or hard-of-hearing, yet professional translators are scarce.
Dignity in Communication
Accessibility isn't a feature; it's a fundamental right. SignSetu provides the dignity of real-time understanding.
"The biggest barrier isn't the inability to hear, but the lack of tools that bridge the gap between spoken words and the visual beauty of Indian Sign Language."
Bridge the gap with smarter tools
