Global Bridge

A real-time voice translation and sign language translation application with video chat capabilities that helps connect with people worldwide.

Features

• Speech Recognition: Uses the built-in browser API (Web Speech) to capture your spoken words.
• Real-Time Translation: Calls a translation service (like Google Translate API) or a local mock translator to convert recognized text.
• Sign Detection: Optional integration with TensorFlow handpose + Mediapipe to detect simple sign language gestures.
• UI Panel: A draggable, resizable panel over your Google Meet window, with toggle buttons for starting/stopping translations.
• Minimize: Collapses to a small icon so it doesn’t obstruct your video call.

Requirements

-Chrome Browser (ideally version 88 or above), since it relies on Chrome’s built-in SpeechRecognition. -Microphone Access: The extension asks for mic permission to do speech recognition.
