Live Captions on Twitch
Twitch Captions Extension
Live Captions for Every Viewer
StreamTranslate adds real-time live captions to your Twitch stream — accessible to deaf and hard-of-hearing viewers, and translated into 30+ languages for your global audience.
Does Twitch Have Built-In Captions? (No — Here's the Fix)
Twitch does not offer automatic live captions for streams. Unlike YouTube, which generates auto-captions for uploaded videos, Twitch has no native real-time captioning for live content. That leaves deaf and hard-of-hearing viewers, as well as viewers who prefer reading to listening, without access to live stream content.
StreamTranslate fills that gap with a native Twitch extension that delivers real-time captions directly inside the Twitch player — no stream overlay, no viewer software, no configuration for viewers beyond clicking a button.
- Twitch has no built-in live captions — StreamTranslate is the solution
- Captions appear as a panel in the native Twitch player
- Works on desktop and mobile Twitch
- Deaf and hard-of-hearing viewers can follow along in real-time
- Also available in translated form — captions in any of 30+ languages
Live Captions vs. Translated Subtitles — StreamTranslate Does Both
StreamTranslate serves two audiences at once:
- Captions (same language): Deaf and hard-of-hearing viewers who speak your language read your words in real-time as you speak them
- Translated subtitles: International viewers who don't speak your language read a translation in their language simultaneously
- A Japanese viewer and an English caption user on the same stream both get what they need — at the same time
- Viewers independently choose whether to see captions, translated subtitles, or neither
How to Add Live Captions to Your Twitch Stream
- Step 1: Go to your Twitch Extensions Dashboard and install StreamTranslate
- Step 2: Create your account at streamtranslate.live
- Step 3: Activate the extension on your Twitch channel (set it as a Component or Panel)
- Step 4: Open StreamTranslate, select your spoken language
- Step 5: Click "Go Live" when you start streaming — captions are live instantly
Viewers will see a CC button in the Twitch player. One click — captions in their preferred language.
Accessibility Benefits for Your Community
Adding captions isn't just good practice — it grows your audience. Studies show that 85% of video is watched without sound in some contexts, and captions increase watch time and engagement across all viewer segments.
- Reach deaf and hard-of-hearing Twitch users who are currently excluded from live streams
- Viewers watching in noisy environments or without headphones can still follow along
- Non-native speakers find captioned streams significantly easier to follow
- Captions improve comprehension of fast speech, accents, and technical vocabulary
- Compliant with accessibility best practices for live content
Caption Accuracy and Speed
StreamTranslate uses neural speech recognition built on the same AI models powering enterprise transcription. Accuracy is highest for clear speech in a quiet environment, but it handles accents, gaming commentary, and rapid speech well.
- Under 2-second latency from speech to captions on screen
- Handles gaming terminology, slang, and streamer vocabulary
- Continuous transcription — no gaps, no restarts
- Translation accuracy improves with context — full sentences, not word-by-word
