Quick Answer
YouTube Live auto-captions are unreliable for real-time use. StreamTranslate provides true real-time subtitles via OBS browser source — baked directly into your video output. Create a room at streamtranslate.live/control, copy the URL, add to OBS as Browser Source at 1920x1080.
Why YouTube Live Needs External Subtitle Tools
YouTube's auto-captions rely on post-processing and are often delayed by 30-60 seconds during live streams. For streamers who want accurate, real-time captions that are visible to all viewers in the video itself, an external tool is essential.
StreamTranslate solves this by processing your microphone audio in the cloud and returning subtitles within 1-2 seconds. The captions appear as an overlay baked into your video output, meaning all YouTube Live viewers see them — regardless of whether YouTube's own caption system is working.
- True real-time captions — not delayed auto-captions
- Baked into video — visible to 100% of viewers
- Works alongside YouTube's built-in caption system
- Translatable into 10+ languages for international audiences
