SignBridge

Our AI-driven accessibility overlay revolutionizes communication for deaf and mute individuals by bridging the gap that exists in mainstream video calling platforms. Using advanced computer vision and deep learning, the system detects English Sign Language gestures in real time via webcam and instantly converts them into clear audible speech and synchronized subtitles—all without requiring any modifications to the underlying video call application. Unlike existing solutions that depend on specialized hardware, external interpreters, or complex platform integrations, our overlay operates as lightweight, universal software compatible with any mainstream video platform. The system prioritizes privacy and performance through on-device processing, ensuring minimal latency while protecting user data. By providing dual voice and subtitle output, the solution creates an inclusive communication experience for both deaf/mute users and hearing participants. The innovation addresses a critical market need: millions of individuals globally face social isolation and exclusion during digital communication due to lack of integrated sign language translation tools. Our platform democratizes accessible communication, empowering underserved communities while opening pathways to educational, professional, and personal opportunities. With over 1.5 million deaf and mute individuals in Bangladesh alone, the solution targets a significant market with immediate impact potential, while remaining scalable across languages, platforms, and use cases globally.
