sign language translated into natural speech in real time

Custom-built dual-hand smart gloves equipped with EMG, flex, and IMU sensors that capture sign language gestures with high fidelity—processed by a machine learning pipeline with AI grammar correction to produce natural, coherent sentences in near real-time.

End-to-End Pipeline

01

Gesture Capture

Flex sensors detect finger bend angles, EMG sensors read muscle activation, and IMUs track hand orientation—all sampled at high frequency across both hands simultaneously.

02

Signal Processing

Raw sensor data is filtered, normalized, and converted into feature vectors. The C++ firmware on the microcontroller handles real-time signal conditioning before transmission.

03

ML Classification

A Scikit-Learn model classifies gesture feature vectors into ASL signs. The model was trained on a custom-collected dataset of dual-hand gesture sequences.

04

Grammar & Speech

An AI-powered grammar correction module converts raw sign sequences into natural, coherent English sentences, then synthesizes speech output in near real-time.

Real-World Impact

Deaf & Hard-of-Hearing Communication

Enables seamless, real-time communication between sign language users and non-signers without an interpreter, breaking down one of the biggest daily barriers.

Education & Classrooms

Allows deaf students to participate in mainstream classrooms with live speech translation of their signing, promoting inclusive education.

Healthcare Access

Empowers deaf patients to communicate directly with healthcare providers during emergencies and consultations without relying on third-party interpreters.

Assistive Technology Research

Advances the field of wearable AI by demonstrating a full end-to-end system—from sensor capture to natural language output—published as peer-reviewed research.
