Teen builds Hindi AI tool to help paralysis patients speak
With no other options in Hindi, Paraspeak offers a breakthrough in speech recognition for dysarthric patients.
An Indian teenager has created a low-cost AI device that translates slurred speech into clear Hindi, helping patients with paralysis and neurological conditions communicate more easily.
Pranet Khetan’s innovation, Paraspeak, uses a custom Hindi speech recognition model to address a long-ignored area of assistive tech.
The device was inspired by Khetan’s visit to a paralysis care centre, where he saw patients struggling to express themselves. Unlike existing English models, Paraspeak is trained on the first Hindi dysarthic speech dataset in India, created by Khetan himself through recordings and data augmentation.
Using transformer architecture, Paraspeak converts unclear speech into understandable output using cloud processing and a neck-worn compact device. It is designed to be scalable across different speakers, unlike current solutions that only work for individual patients.
The AI device is affordable, costing around ₹2,000 to build, and is already undergoing real-world testing. With no existing market-ready alternative for Hindi speakers, Paraspeak represents a significant step forward in inclusive health technology.
