Use a live stream subtitle generator with StreamTranslate — real-time translated subtitles on your Twitch, YouTube, Kick, or TikTok stream in under 60 seconds. No plugins, no downloads, just an OBS browser source URL.
Live Stream Subtitle Generator is the process of adding real-time translated captions to a live broadcast so international viewers can follow along in their own language. StreamTranslate handles the full pipeline: your voice is transcribed via Deepgram AI, translated by multiple neural MT providers racing for the fastest result, and displayed on your OBS overlay in under 2 seconds.
Unlike post-production captioning tools, StreamTranslate works live — every word you say is captioned and translated within seconds, giving your international audience an experience comparable to watching native-language content. No manual input required.
StreamTranslate uses Deepgram Nova-2 and Nova-3 AI for real-time speech recognition, then races multiple translation providers (DeepL, Google, and others) to return the fastest result. Translated subtitles appear on your OBS browser source overlay in under 2 seconds end-to-end.

Brazil is the #2 country on Twitch by viewers. Japan, Korea, Spain, and Mexico round out the top streaming markets outside the US. If you stream only in English without translation, you're invisible to billions of potential viewers. Streamers who add live translated subtitles typically see 15–40% viewer growth from international audiences within weeks.
Beyond viewer growth, subtitles improve accessibility for deaf and hard-of-hearing viewers, increase engagement in noisy environments, and make your clips perform better on TikTok and Reels where silent viewing is the norm.
