Twitch has a closed caption system based on EIA-608 captions. In theory, streamers can feed captions into it and viewers can enable them via the CC button in the player. In practice, almost nobody uses it — because:
The result: virtually no Twitch streams have working captions, and even those that do aren't reaching the international viewers who need translation — not just transcription.
Here is what Twitch's own data shows: the platform has viewers in every country on earth, and the majority are non-native English speakers. When you stream without translated subtitles, you are invisible to them — not because they can't find your stream, but because they can't follow it.
Adding translated subtitles is not an accessibility feature. It is a growth strategy. Spanish-speaking streamers who add English subtitles see their clips shared internationally. English-speaking streamers who add Spanish subtitles open themselves to the single largest non-English language community on the internet.
StreamTranslate is built specifically for this. It captures your mic audio, runs it through real-time speech recognition and translation, and displays subtitles as an overlay on your stream — in any of 30+ languages, visible to every viewer automatically, with no opt-in required.
StreamTranslate integrates with OBS, Streamlabs, and XSplit via browser source — the same way most overlays work. There are no plugins to install, no software to download, and no viewer-side settings to configure.
Latency is under 500ms. Subtitles are styled as an overlay burned into your stream image — visible on every platform, every device, every viewer. No CC button. No opt-in. Just subtitles, live.
English-only captions help deaf and hard-of-hearing viewers who already speak English. That is a real and worthwhile audience — but it is a subset of your existing English-speaking viewers. Translated subtitles do something different: they add entirely new language communities to your potential audience who currently cannot watch you at all.
StreamTranslate supports dual-language subtitles on Pro and Unlimited plans — meaning you can show two translations simultaneously. Stream in English, show Spanish subtitles for your Latin American viewers and Japanese subtitles for your JP audience, all at the same time.
Based on Twitch viewership data, these are the highest-impact language additions for English-speaking streamers:
StreamTranslate lets you switch languages between streams or set a default. You can run Spanish on weekdays and Portuguese on weekends based on when your analytics show the most international traffic.
