What is Twitch Stream Translation? [Complete Guide]

Twitch stream translation is the process of adding real-time translated captions to a Twitch live broadcast, enabling non-English viewers to understand the streamer. Twitch itself has no built-in live translation feature, so streamers use third-party tools like StreamTranslate.

Twitch Has No Native Translation

Twitch does not offer built-in live translation or automatic subtitles. Streamers must use third-party tools to reach non-English viewers.

How Twitch Stream Translation Works

A tool like StreamTranslate captures the streamer's mic audio, transcribes and translates it, and delivers translated captions via an OBS browser source.

Setup Steps

  1. Go to streamtranslate.live/control
  2. Choose source and target language
  3. Copy the overlay URL
  4. Add as browser source in OBS → paste URL
  5. Go live — captions appear in real time
