SEHAT is a modern, multilingual video consultation platform designed to break down language barriers. Using real-time speech recognition, translation, and synthesis, it enables seamless communication between users speaking different languages.
In an increasingly connected world, language differences can be a significant obstacle to effective communication, especially in critical sectors like healthcare and international business. SEHAT (meaning "health" in Hindi) addresses this challenge head-on by providing an intuitive video calling experience with powerful, real-time translation capabilities.
This project integrates secure WebRTC video streams with the Google Translate API to capture, translate, and voice-synthesize conversations, allowing all participants to communicate effortlessly in their native language.
- Secure Video Meetings: Peer-to-peer, encrypted video and audio streams powered by WebRTC.
- Real-time Translation: Instant speech recognition and translation between multiple languages.
- Multilingual Support: Supports a wide range of languages including English, Hindi, Kannada, and more.
- Voice Synthesis: Reads translated text aloud, creating a natural conversational flow.
- Room-Based Meetings: Simple, shareable links for joining private consultation rooms.
- Responsive UI: A clean, modern, and easy-to-use interface that works on all devices.
This project leverages a modern tech stack to deliver a real-time experience:
- Node.js: Server-side JavaScript runtime.
- Express.js: Minimalist web framework for Node.js.
- Socket.IO: Enables real-time, bidirectional event-based communication.
- WebRTC: Provides peer-to-peer communication capabilities in the browser.
- Google Cloud Translate API: Powers the speech recognition and translation features.
