Audio Transcription Live

Audio Transcription is a powerful extension that turns your browser into a real-time interpreter. It captures any audio playing in a tab (transcribing it via Whisper AI) or reads existing video subtitles, translates them live, and reads the results back to you via Text-to-Speech (TTS).

🌟 Designed with privacy and efficiency in mind, it is optimized to run smoothly on low-resource computers and operates as independently from cloud services as possible. Compatible with Linux, Windows, and macOS, this extension acts as a true Live Interpreter for any media stream.

✨ Key Features:

• 🎬 Subtitle TTS Mode: Read aloud and translate existing subtitles from YouTube, Twitch, or any HTML5 video without needing a local server.
• 🌐 Source Language Control: Rely on smart auto-detection, or manually select the subtitle language for maximum accuracy.
• 🗣️ Real-Time Speech-to-Speech: Listen to live translations with a natural, fluid voice that buffers complete sentences for a seamless experience.
• 📝 Live Audio Transcription: Fast and accurate transcription from scratch using your local machine's processing power with OpenAI's Whisper AI (WhisperLive server required).
• 🤖 Instant Translation: Translate live text using Google Translate (free) or the latest Google Gemini (Flash-Lite) & Gemma 4 AI models.
• 🖼️ Flexible UI Modes: View transcripts in a floating overlay or a dedicated Standalone popup window.
• 🛡️ Total Privacy: Local audio processing and transparent open-source code.

⚙️ SERVER INSTRUCTIONS & SOURCE CODE:

The Subtitle TTS mode works completely out-of-the-box. However, to use the advanced "Live Audio Transcription" feature, you must run the local WhisperLive server on your computer.
