StreamVox - AI Live Translator

StreamVox represents a significant evolution in personal computing, transforming your Windows PC into a universal communication hub. It is a real-time AI translator that adds live subtitles and instant translation to any audio source on your computer. This tool is designed for the modern, globally-connected user, breaking down language barriers that once hindered productivity and entertainment. Whether you're a professional navigating international video calls, a gamer collaborating with teammates worldwide, a student consuming foreign-language content, or simply someone connecting with friends and family abroad, StreamVox empowers you to understand and be understood. Its core value proposition lies in its seamless, privacy-first integration into your existing workflow. By processing audio locally with ultra-low latency AI and offering a customizable, always-on-top overlay, StreamVox doesn't require you to change how you work or play—it simply enhances your capability to participate in a multilingual world, turning every audio stream into an accessible conversation.

Smart Per-App Audio Capture

StreamVox evolves beyond basic system-wide capture with its intelligent per-app isolation. You can select specific applications like Zoom, Chrome, or Discord for translation, while automatically ignoring all other background noise and audio. This precision ensures translations are clean, accurate, and relevant, transforming a cluttered audio environment into a focused communication channel. It's a foundational feature that marks the shift from passive translation to active, context-aware assistance.

Customizable, Transparent Overlay

The application features a dynamic floating overlay that stays on top of any window or full-screen application. You have complete control over its appearance, allowing you to adjust font size (from 12px to 72px), text color, and, crucially, the overlay's transparency. This lets you integrate subtitles naturally into your viewing experience, whether for immersive gaming, watching movies, or during critical presentations, without obstructing valuable screen real estate.

Bidirectional Translation Modes

StreamVox supports a mature two-way communication flow. You can translate incoming system audio from calls, games, or videos, and simultaneously translate your own microphone input for outgoing speech. This bidirectional capability facilitates natural, real-time conversations, allowing all parties to communicate in their preferred language. It's the feature that turns a simple subtitle tool into a genuine dialogue facilitator.

Extensive Language & Privacy Framework

With support for 49+ input and AI-powered target languages, and an app interface localized in 12 languages, StreamVox is built for a global audience. This extensive support is coupled with a strict privacy-first architecture. All audio is processed in real-time for translation and is never stored or sent to external servers, ensuring your conversations, meetings, and media consumption remain completely confidential and secure.

Professional International Meetings

Elevate your global business communications by using StreamVox in Zoom, Microsoft Teams, or Google Meet. Get real-time subtitles for every participant, allowing you to follow complex discussions and technical details without language being a barrier. This transforms international collaboration from a challenge into a seamless part of your professional growth, ensuring you never miss a critical point.

Immersive Gaming & Live Streaming

For gamers and streamers, StreamVox unlocks a new level of community and competition. Understand in-game voice chat from international teammates or provide live translated subtitles for your audience. The line-by-line display mode is perfect for fast-paced chat, helping you coordinate strategies and engage with a global viewer base in real-time, fostering a more inclusive community.

Accessible Foreign Media Consumption

Progress from waiting for official subtitles to instant understanding. Watch foreign-language films on Netflix, follow creators on YouTube, or enjoy live streams on Twitch with live translations overlaid directly on the video player. This use case democratizes content, allowing you to explore a vast world of media and education on your own terms, without delay.

Connected Personal Communication

Bridge personal gaps by translating mobile phone calls live on your PC screen through Phone Link integration. Communicate clearly with friends and family abroad during video or audio calls on any platform. This personal application of the technology strengthens connections, making distance and language differences a minor detail rather than a division.

Is my audio data kept private with StreamVox?

Yes, absolutely. StreamVox is built with a privacy-first principle. All audio processing for translation is done in real-time using on-device AI capabilities. The audio is never recorded, stored, or sent to any external cloud servers. Your conversations and media audio remain entirely on your computer.

What are the system requirements for StreamVox?

StreamVox requires a PC running a 64-bit version of Windows 10 or Windows 11. A stable internet connection is necessary for the AI translation processing, and a microphone is required if you wish to use the bidirectional translation feature for your own speech.

Can I use StreamVox for free?

Yes, StreamVox offers a Free Starter plan that provides 20 minutes of translation time per day at no cost forever. This allows you to fully test the core features, such as per-app capture and the customizable overlay, during short meetings or media sessions before deciding to upgrade for more extensive use.

How does the per-app audio capture work?

This smart feature allows you to select individual applications (e.g., your browser, Discord, or a specific game) from a list. StreamVox will then capture audio only from those selected sources, effectively isolating it from all other system sounds, music, or notification noises. This results in cleaner, more accurate translations focused solely on the content you need.

The Pro plan ($8.99/month) includes 40 hours of translation per month. The Pro+ plan ($14.99/month) offers 70 hours monthly.
