StreamVox - AI Live Translator

StreamVox - AI Live Translator is a revolutionary Windows application designed to dismantle language barriers in real-time. It functions as a powerful, intelligent layer over your entire PC audio ecosystem, providing live subtitles and instant translation for any sound source. Whether it's a multilingual business call on Zoom, an untranslated foreign film on Netflix, a fast-paced in-game voice chat, or a live-streamed conference, StreamVox processes the audio and displays translated text directly on your screen with ultra-low latency. It is built for a global audience: professionals engaging in international collaboration, gamers connecting across regions, students and enthusiasts consuming foreign media, and anyone who needs to understand or be understood without language constraints. Its core value proposition lies in its seamless, privacy-first, and highly customizable integration into the Windows experience, offering a universal translation tool that is both powerful enough for professional use and accessible enough for daily personal enrichment.

Universal Audio Capture & Per-App Isolation

StreamVox offers three distinct audio capture modes to fit any scenario. You can capture your entire system audio, use just your microphone, or, most powerfully, utilize Per-App Capture. This feature allows you to isolate audio from specific applications like Zoom, Chrome, or Discord individually. This means you can translate a meeting in one window without capturing background music or notifications from other apps, ensuring clean, focused subtitles and automatically ignoring irrelevant noise.

Intelligent, Customizable Floating Overlay

The application employs a transparent overlay that stays on top of any other window or full-screen application, from video players to video games. This "invisible" smart overlay is highly customizable, allowing you to adjust font size (from 12px to 72px), text color, background, and crucially, the overlay's opacity. You can make it nearly transparent for a subtle guide or more solid for easy reading, with all preferences saved automatically for a consistent experience.

Extensive Language Support & Bidirectional Translation

Powered by advanced AI, StreamVox supports an impressive array of 49+ input languages and can translate into 49+ target languages. This extensive support ensures coverage for most global languages. Furthermore, it supports bidirectional translation, meaning it can translate both incoming system audio (what you hear) and outgoing microphone audio (what you say), facilitating two-way conversations in real-time during calls or meetings.

Privacy-First Architecture & Low Latency AI

StreamVox is built with a strong commitment to user privacy. All audio processing for translation is done in real-time, and the audio data is never stored on servers or recorded, ensuring your conversations and media consumption remain confidential. This is coupled with an ultra-low latency AI engine that delivers translations quickly enough to keep pace with live dialogue, making interactions feel natural and seamless rather than disjointed.

International Business Calls & Virtual Meetings

Professionals can use StreamVox to participate confidently in global meetings on platforms like Zoom, Microsoft Teams, or Google Meet. By capturing the app's audio directly, it provides real-time subtitles of colleagues speaking in different languages, breaking down communication barriers and ensuring no nuance is lost in critical discussions, all while maintaining meeting flow with low-latency translations.

Consuming Foreign Media & Live Streams

Movie enthusiasts, anime fans, and viewers of international content on YouTube, Netflix, or Twitch can watch videos without relying on official or fan-made subtitles. The overlay works on top of any video player, providing instant live translation of dialogue and commentary, unlocking a vast world of content previously inaccessible due to language constraints.

Cross-Language Gaming & Streaming

Gamers playing on international servers or watching foreign streamers can use StreamVox to understand in-game voice chat, strategy calls, and live commentary. The line-by-line display mode is perfect for fast-paced gaming chats, allowing players to react in real-time and fully engage with a global gaming community without language being a hindrance.

Translating Mobile Phone Calls on PC

Through integration with Microsoft's Phone Link feature, StreamVox extends its capability to mobile communications. Users can connect their iPhone or Android phone to their PC and see live subtitles and translations for their phone calls displayed directly on their computer screen, turning any mobile conversation into a translatable, text-aided dialogue.

Is my audio data stored or recorded by StreamVox?

No. StreamVox operates on a strict privacy-first principle. All audio processed for live translation is handled in real-time by the AI engine and is never stored on disk, uploaded to a permanent server, or recorded. The translation happens instantaneously, and the audio data is discarded immediately after processing, ensuring complete confidentiality.

What are the system requirements for StreamVox?

StreamVox is designed for modern Windows operating systems. It requires a PC running Windows 10 or Windows 11 (64-bit versions). You will need a stable internet connection for the AI translation processing to function, as well as standard audio input/output devices (speakers and a microphone if using bidirectional translation).

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 plan includes access to all 49+ supported languages and core features like system and microphone capture, allowing you to fully test and experience the application's capabilities before committing to a paid subscription for more usage time.

How does the Per-App Capture feature work?

The Per-App Capture feature allows you to select specific running applications (e.g., Discord, Chrome, Zoom) from a list. StreamVox will then only capture and translate the audio from those selected apps, ignoring all other system sounds and audio from unselected applications. This is ideal for focusing on a single meeting or media source without interference from notifications, music players, or other background noise.

The Free Starter plan is $0 forever and provides 20 minutes of translation per day. The Pro plan costs $8.99 per month for 40 hours of translation time monthly.
