How Twitch Viewers
Get Subtitles
Watching a Twitch stream and want subtitles? Here's how it works — and how streamers can turn on real-time subtitles for all their viewers in 49 languages.
How Viewers Get Subtitles on Twitch
Twitch does not have built-in automatic subtitles for live streams. To get subtitles on a Twitch stream, the streamer must install a subtitle extension like StreamTranslate. Here's how it works:
- The streamer installs StreamTranslate from the Twitch Extensions Marketplace
- When the streamer is live with StreamTranslate active, a CC / Subtitles button appears in the Twitch player for all viewers
- Viewers click the button, choose their language, and subtitles appear in a panel in real-time
- Viewers can toggle subtitles on/off and change language at any time — independently of other viewers
If the streamer doesn't have StreamTranslate installed, there are no real-time subtitles available for that stream.
What Viewers See: The Subtitle Experience
When StreamTranslate is active on a Twitch channel, viewers see a new icon in the Twitch player toolbar — similar to a CC (closed captions) button. Here's the viewer experience:
- Click the CC/Subtitles button in the player
- A language selector appears — choose your language (Spanish, French, Japanese, etc.)
- A subtitle panel opens below or beside the video (depending on your layout)
- As the streamer speaks, new subtitle lines appear in real-time
- Old lines fade out automatically — the panel stays clean
- You can resize, reposition, or close the subtitle panel at any time
For Viewers: What Languages Are Available?
StreamTranslate supports 49 languages for viewers. The available languages depend on which languages the streamer has enabled, but most streamers allow all supported languages. Common viewer languages include:
- Spanish (Latin America and Spain)
- Portuguese (Brazil and Portugal)
- French, German, Italian, Dutch
- Japanese, Korean, Chinese (Simplified and Traditional)
- Arabic, Hindi, Turkish, Russian
- Polish, Swedish, Norwegian, Vietnamese, Indonesian, and more
Do Viewers Need to Install Anything?
No — viewers do not need to install anything. The StreamTranslate extension is installed by the streamer on their Twitch channel. When you visit a channel where it's active, the subtitle panel is available automatically in your Twitch player.
You don't need a StreamTranslate account. You don't need a browser extension. You don't need to download any software. Just click the CC button in the Twitch player and choose your language.
For Viewers: My Favorite Streamer Doesn't Have Subtitles — What Can I Do?
If your favorite streamer doesn't have StreamTranslate installed, the best thing to do is tell them about it. Here's what you can share:
- StreamTranslate is a free Twitch extension that gives every viewer subtitles in their language
- It takes less than 5 minutes to set up
- Viewers don't need to install anything — it works automatically once the streamer activates it
- Send them this link: streamtranslate.live or the Twitch extension page
For Streamers: How to Give Your Viewers Subtitles
If you're a streamer reading this because your international viewers or accessibility-minded community has asked for subtitles, here's the quick version:
- Step 1: Install StreamTranslate from the Twitch Extensions Marketplace
- Step 2: Create your account at streamtranslate.live

It's the only Twitch extension that provides real-time translated subtitles natively to viewers without any viewer-side setup.
