Professional captioning for live events and streams. StreamTranslate delivers our industry-leading speech AI accuracy in 125+ languages with OBS and vMix integration — enterprise captioning quality at creator-friendly prices.
Caption Your Live Event TodayThe line between a live event and a live stream has blurred almost completely. A corporate product launch is simultaneously a live event for in-person attendees and a live stream for remote viewers. A gaming tournament is a live event for venue attendees and a Twitch stream for online viewers. A university conference is a live event in its lecture hall and a YouTube Live broadcast for students who could not make it.
This convergence means that captioning for live events and captioning for live streams is increasingly the same problem. You need captions that work for the physical space, captions that overlay on the stream, and potentially captions in multiple languages for international audiences — all running simultaneously, all with the same accuracy and latency requirements.
StreamTranslate handles all of it. The our industry-leading speech AI engine processes your event audio in real time, delivering captions via OBS browser source that can be overlaid on your stream output, displayed on event signage, or both. The 125-language support covers everything from English-to-Spanish translation for a US-based audience to full multilingual broadcasts for international conferences. See how to set it up for your specific event format.

Integrates with OBS for streaming setups and vMix for professional broadcast productions. Works with any video switcher or production software that supports browser sources.
For years, enterprise-grade live event captioning required enterprise-grade budgets. CART stenographers billing at $150-300 per hour, simultaneous interpreters charging thousands per day, captioning agencies with multi-day booking requirements — the cost of professionally captioned live events was a barrier that excluded smaller organizations, nonprofits, universities, and startups from offering the level of accessibility their audiences deserved.
our industry-leading speech AI changes the economics. The same ASR accuracy that enterprise broadcast companies use is now available through StreamTranslate at pricing accessible to event organizers of any size. Whether you are running a 50-person webinar or a 5,000-person virtual conference, StreamTranslate delivers advanced AI-powered captions in 125 languages without the per-hour, per-language billing structure that makes traditional enterprise captioning prohibitively expensive.
For event organizers already using OBS or vMix for their live broadcast production, the integration path is straightforward. Add StreamTranslate as a browser source in OBS, or use vMix browser input to pull in the caption overlay. The captioned output can then be directed to your stream destination, your event platform, or both. Check our pricing page to find the plan that fits your event schedule.
