LingoYou

Real time captions, translation and AI voice interpretation for live events

WebRTCmediasoupSpeech to TextAI TranslationNode.js

LingoYou is a real time communication platform built to remove language barriers from live meetings, webinars and online events. It delivers live speech to text captions, real time translation and AI generated voice interpretation across multiple languages while supporting natural multi speaker conversations.

The system runs on a scalable WebRTC architecture built on mediasoup, which keeps audio and video latency low while the server handles transcription and language processing. Each speaker is processed independently so captions stay accurate and clearly attributed even when several people talk in the same session.

It is designed for professional and high stakes settings such as international meetings, classrooms, conferences and live events where timing and reliability matter. The platform handles simultaneous interpretation, clean subtitle rendering and synchronized playback of the translated audio so every participant follows along in their own language.
