About StreamVox - AI Live Translator

Multi-Source Audio Capture with Per-App Isolation

StreamVox offers three distinct audio capture modes to suit any situation: System Audio, Microphone, and Per-App Capture. The Per-App isolation feature is particularly advanced, allowing users to select specific applications like Zoom, Chrome, or Discord for translation while automatically ignoring all other background noise and system sounds. This ensures clean, focused subtitles by capturing only the audio you intend to translate, which is critical for maintaining clarity during meetings or while gaming.

Intelligent and Customizable Transparent Overlay

The application utilizes a persistent transparent overlay that stays on top of any other window or full-screen application. Users have extensive control over its appearance, including adjustable font size (from 12px to 72px), text color, and overlay opacity. This customization allows the subtitles to be integrated unobtrusively into the viewing experience, whether for cinematic immersion during movies or for quick readability during fast-paced gaming sessions and live streams.

Extensive Language Support and Bidirectional Translation

Powered by advanced AI, StreamVox supports an impressive repertoire of 49+ input languages and can translate into 49+ target languages. Furthermore, the application supports bidirectional translation, meaning it can translate both incoming system audio (like a caller's voice) and your own microphone input in real time. This facilitates natural two-way conversations where all participants can communicate in their preferred language, making it ideal for business calls and international collaborations.

Privacy-First Architecture and Ultra-Low Latency

StreamVox is built with a strong commitment to user privacy. All audio processing for translation is performed in real-time, and the audio data is never stored on servers or locally after the translation is complete. Coupled with its optimized ultra-low latency AI engine, this ensures that translations appear almost instantaneously, making conversations feel natural and fluid without disruptive delays that can hinder real-time interaction and comprehension.
