SignTalk AI Translator

Real-time AI system for sign language translation, breaking communication barriers and promoting inclusivity for deaf communities.

Project Image

The SignTalk AI Translator project develops revolutionary technology to bridge communication barriers between deaf and hard-of-hearing communities and the broader hearing world. By leveraging advanced computer vision, machine learning, and natural language processing, SignTalk creates real-time translation systems that convert sign language gestures into spoken language and text, enabling seamless communication across diverse settings. Our research addresses the critical accessibility challenges faced by millions worldwide who use sign language as their primary means of communication. The system employs sophisticated computer vision techniques to recognize hand shapes, movements, facial expressions, and body language that constitute sign language, then translates these into natural language outputs with appropriate context and intonation. SignTalk represents a comprehensive approach to accessibility technology, combining gesture recognition, linguistic analysis, and human-computer interaction to create inclusive communication solutions that work across different sign languages, lighting conditions, and user abilities.

Objectives

SignTalk AI Translator pursues transformative objectives to create inclusive communication technology that empowers deaf and hard-of-hearing communities while advancing the field of human-computer interaction.

Advanced Gesture Recognition

Develop highly accurate computer vision systems capable of recognizing complex sign language gestures including hand shapes, movements, facial expressions, and body language in real-time across diverse users and environments.

Real-time Language Translation

Create optimized AI models that provide instantaneous translation from sign language to spoken language and text with natural intonation, context awareness, and grammatical correctness.

Multi-modal Communication Support

Support bidirectional translation between multiple sign languages (ASL, BSL, ISL, etc.) and spoken languages, enabling communication across linguistic and cultural boundaries.

Adaptive Learning Systems

Implement continuous learning mechanisms that adapt to individual signing styles, regional variations, and new vocabulary while maintaining privacy and user personalization.

Accessible Technology Design

Develop user interfaces and interaction models that prioritize accessibility, ease of use, and integration with existing assistive technologies for the deaf community.

Methodology

Our research methodology integrates computer vision, machine learning, linguistics, and human-centered design to create comprehensive sign language translation technology.
