Twitch Live Translation
Stream to the Whole World
StreamTranslate translates your Twitch stream live — viewers in every country read subtitles in their language as you speak. The only native Twitch extension for real-time live translation.
What Is Twitch Live Translation?
Twitch live translation means converting your spoken stream audio into subtitles in another language in real-time — while you're live. Not after the stream (like VOD subtitles). Not with a delay of minutes. In real-time, under 2 seconds from your mouth to a viewer's screen.
StreamTranslate makes this possible through a native Twitch extension. When viewers visit your channel while you're live and StreamTranslate is running, they see a subtitle panel in the Twitch player where they can select their language and read along in real-time.
- Real-time — under 2 seconds from speech to viewer subtitle
- 30+ languages supported simultaneously
- Each viewer picks their own language independently
- Native Twitch extension — no viewer software required
- No impact on your stream quality or your streaming PC
Why StreamTranslate Is the Only Real Option
There are a few approaches to translating a Twitch stream. Here's why StreamTranslate is the right one:
- OBS browser source overlays: Burn subtitles into the video in one language. Every viewer sees the same language — no per-viewer control. StreamTranslate works alongside this approach but also offers the extension-based method.
- Third-party browser extensions for viewers: Require each viewer to install a separate extension. Doesn't work on mobile Twitch. Puts the burden on viewers.
- StreamTranslate Twitch Extension: Installed once by the streamer. Every viewer on desktop and mobile gets a subtitle panel. Each viewer independently picks their language. No viewer installs anything.
StreamTranslate is the only solution that is both natively integrated with Twitch and provides per-viewer language selection.

From install to live translation: under 5 minutes for first-time setup.
