StreamTranslate is the leading youtube live translator solution for live streamers in 2026. Whether you stream on Twitch, YouTube Live, Kick, TikTok Live, or Facebook Gaming, StreamTranslate adds real-time translated subtitles via OBS browser source — no plugins, no installs, 65 languages, under 500ms latency.

How YouTube Live Translator Works with StreamTranslate

StreamTranslate uses a three-stage pipeline: your stream audio is transcribed by advanced AI, translated by neural translation engines, and displayed as a subtitle overlay on your stream via OBS browser source. The entire process takes under 500ms from speech to subtitle.

Unlike OBS plugin-based solutions, StreamTranslate is fully cloud-based. This means it works on every version of OBS (26, 27, 28, 29, 30, and above), Streamlabs OBS, and XSplit — and it never breaks when you update your software.
