Sign letters with your hand — Voxetu speaks them aloud
India is home to an estimated 18 million Deaf people, and Indian Sign Language (ISL) is their first language. Voxetu now recognises ISL hand gestures using your phone's front camera and speaks the finished word aloud — no gloves, no sensors, no extra hardware.

Real examples
Deaf-blind user, age 34 — Pune
"I have been using ISL all my life but my hearing carers do not understand sign language. Now I sign letters into Voxetu and it speaks them aloud — my carer hears every word. I signed H-E-L-P W-A-T-E-R and the app said it clearly. First time in years I communicated without an interpreter." — Rahul S.
ISL teacher using Voxetu with students — Delhi
"I use Voxetu in my ISL classroom. A student signs a letter, the app types it, and they see immediately whether they got it right. One student's V showed 91% confidence, but his W only showed 43% — he instantly understood he needed to spread his fingers more." — ISL Teacher
ALS patient who knows ISL — Kolkata
"My father was a CODA (child of deaf adults) and knew ISL his whole life. When ALS took his voice and hands, he was left with only minimal finger movement. The ISL mode detects even partial hand shapes — his first signed word in Voxetu was L-O-V-E." — Daughter
