StreamVox - AI Live Translator

StreamVox is a powerful, real-time AI translation and live subtitle application designed exclusively for Windows PCs. It solves the pervasive problem of language barriers by instantly translating any audio source on your computer into your preferred language. Whether you're on an international Zoom call, watching a foreign-language stream on Twitch, playing a multiplayer game with global teammates, or enjoying a movie without official subtitles, StreamVox provides immediate understanding. Its core value proposition lies in its seamless, privacy-first integration into your existing workflow. The application acts as an intelligent, transparent overlay that captures audio, processes it with ultra-low latency AI, and displays translated subtitles directly on your screen without interrupting your activity. It is built for professionals, gamers, content consumers, and anyone who needs to communicate or consume media across languages. By offering per-app audio capture, it ensures you only translate what you need, eliminating background noise and focusing on clarity. With support for 49+ languages and a flexible pricing model that includes a generous free tier, StreamVox empowers users to break down language walls instantly and effortlessly.

Per-App Audio Capture & Isolation

This intelligent feature allows you to target translation for specific applications only. Instead of capturing all your PC's audio, you can isolate and translate sound from individual programs like Zoom, Discord, Chrome, or a game. This smart isolation automatically filters out background noise from other apps, notifications, or system sounds, ensuring the translation is focused, accurate, and relevant only to the content you care about. It provides unparalleled control over your audio environment.

Customizable, Always-on-Top Overlay

StreamVox displays translations in a transparent overlay window that stays on top of any other application, whether it's a full-screen game or a video player. You have full control over its appearance to suit your needs: choose between line-by-line mode for fast-paced chats or paragraph mode for natural reading. Adjust the font size (from 12px to 72px), text color, and, crucially, the window opacity to make the subtitles as visible or as unobtrusive as you desire, creating a perfect viewing experience.

Bidirectional Audio Translation

StreamVox doesn't just translate what you hear; it can also translate what you say. It supports capturing both system audio (the sound coming from your PC) and your microphone input simultaneously. This bidirectional capability is essential for live conversations, allowing you to speak in your native language and have your words translated for others on the call, and vice-versa. It facilitates true two-way, real-time communication without requiring all parties to use the same language.

Phone Link Integration for Mobile Calls

Extend StreamVox's power to your smartphone calls. By using Microsoft's Phone Link feature to connect your iPhone or Android to your Windows PC, StreamVox can capture the audio from your mobile calls. This means you can see live subtitles and translations for your phone conversations directly on your computer screen, turning any mobile call into an accessible, cross-language dialogue without needing any special setup on the other person's device.

International Business Meetings & Calls

Professionals can participate confidently in global meetings on platforms like Zoom, Microsoft Teams, or Google Meet. StreamVox provides real-time subtitles, allowing you to follow every word spoken by international colleagues or clients in your native language. The low latency ensures the conversation feels natural, and the per-app capture keeps the translation focused solely on the meeting audio, ignoring other desktop distractions.

Gaming with Global Teams

Gamers playing multiplayer titles with international friends or on global servers can overcome language barriers in voice chat. StreamVox translates team communications in real-time, displayed as an overlay on your game screen. This allows for coordinated strategy, clear callouts, and social interaction, enhancing teamwork and the overall gaming experience regardless of the languages spoken by other players.

Consuming Foreign Language Media

Enjoy movies, TV shows, YouTube videos, Twitch streams, and other content in any language without relying on official or fan-made subtitles. Simply play the media in your browser or media player, and StreamVox will overlay accurate, real-time translations. This is perfect for watching live streams, news broadcasts, or educational content that hasn't been formally translated, opening up a world of media.

Translating Mobile Phone Conversations

For personal or business calls on your smartphone where language is a barrier, StreamVox's Phone Link integration is a game-changer. Connect your phone to your PC, and the app will transcribe and translate both sides of the conversation live on your monitor. This makes communicating with family, friends, or service providers in another language straightforward and effective.

Is my audio data private and secure?

Yes, StreamVox is built with a privacy-first philosophy. Your audio is processed in real-time by the AI translation engine and is never stored on StreamVox's servers or your local disk. The processing happens on-the-fly to generate the subtitles, and the raw audio data is discarded immediately afterward, ensuring your conversations and audio remain confidential.

What are the system requirements for StreamVox?

StreamVox requires a PC running a 64-bit version of Windows 10 or Windows 11. You will need a stable internet connection for the AI translation processing to function. The application is downloaded and installed via the official Microsoft Store, ensuring easy updates and secure distribution.

How does the per-app audio capture work?

When you select "Per-App Capture" mode, StreamVox presents a list of currently running applications that are outputting audio. You can then select one or more specific apps (e.g., Chrome, Discord, a game executable) from this list. StreamVox will then isolate and capture audio only from those selected sources, ignoring all other system and application sounds for clean, focused translation.
