StreamVox - AI Live Translator

StreamVox is your lightweight, real-time translation companion for Windows. It instantly adds live subtitles and translation to any audio playing on your PC. Whether you're on an international Zoom call, watching a foreign-language stream, playing a game with global teammates, or enjoying a movie, StreamVox breaks down language barriers in real time. It's designed for simplicity and ease-of-use, working seamlessly in the background. The tool captures audio directly from your system, specific apps, or microphone, processes it with ultra-low latency AI, and displays the translation in a customizable, always-on-top overlay. With a strong focus on privacy—your audio is never stored—and support for over 49 languages, StreamVox is the essential micro-tool for students, professionals, gamers, and content consumers who need instant understanding without the complexity.

Smart Per-App Audio Capture

Isolate and translate audio from only the applications you choose, like Zoom, Chrome, or Discord. This smart feature automatically ignores background noise and other system sounds, ensuring your translations are clean, accurate, and focused solely on the content that matters to you. It gives you precise control over your audio sources.

Customizable Transparent Overlay

The translation appears in a floating window that stays on top of any other application. You can fully customize the display to suit your needs: adjust font size from 12px to 72px, change text color, and modify the overlay's transparency. This ensures subtitles are readable without blocking your view, perfect for gaming or watching videos.

Bidirectional & Multi-Source Audio Modes

StreamVox offers three flexible audio modes to fit any scenario. Capture 'System Audio' for movies and streams, use 'Microphone' mode to translate your side of a conversation, or employ the powerful 'Per-App Capture'. This bidirectional capability lets you translate both what you hear and what you say in real time.

Extensive Language & Privacy Support

Access real-time translation for 49+ input and 49+ AI-powered target languages. The app interface itself is available in 12 languages for global accessibility. Most importantly, StreamVox is built with a privacy-first design; all audio is processed instantly on the fly and is never recorded or stored on any server.

International Calls & Virtual Meetings

Translate conversations live on platforms like Zoom, Microsoft Teams, Google Meet, and Discord. Follow along with colleagues or clients in your native language during business conferences, online classes, or community meetings, making cross-language collaboration smooth and natural.

Gaming & Live Streaming

Get real-time subtitles for in-game voice chat from teammates around the world. StreamVox helps you coordinate and socialize in multiplayer games without language barriers. Streamers can also use it to understand and interact with a global audience commenting in different languages.

Watching Foreign Media & Streams

Enjoy YouTube videos, Netflix shows, Twitch streams, or anime without waiting for official subtitles. Simply play the content and let StreamVox overlay live translations directly on your video player. It's perfect for consuming international news, entertainment, and educational content.
