Twitch Studio + Subtitles
Twitch Studio has no subtitles.
Here's how to add them.
Twitch Studio is built for simplicity — which means live captions, real-time translation, and subtitle overlays are completely missing. StreamTranslate fills that gap. Paste one URL as a browser source and you're broadcasting with subtitles in under 60 seconds.
No downloads. No API keys. Works in Twitch Studio, OBS, Streamlabs, and more.
The Short Answer
Twitch Studio supports browser source layers — the same way you add alerts or overlays. Add StreamTranslate's URL as a browser source, size it to your canvas, and your spoken words appear as live captions on stream. Translation into 30+ languages is included. Takes about 60 seconds to set up.
ℹ Why Twitch Studio Has No Built-In Subtitles
Twitch Studio is Twitch's own beginner-friendly streaming app. It abstracts away the complexity of OBS — which is exactly why it's popular with newer streamers. That same simplicity means advanced features like live captions, speech recognition, and translation overlays are not included. Twitch has no roadmap to add them. Third-party browser source tools are the intended path.
How to Add Subtitles to Twitch Studio
Setup — takes about 60 seconds
- Go to streamtranslate.live and create your overlay. Choose your language, translation target, font, and colors.
- Copy your unique overlay URL (it looks like
streamtranslate.live/overlay/your-room-id).
- Open Twitch Studio. In your scene, click + Add Layer and choose Browser Source.
- Paste your StreamTranslate URL into the URL field. Set width to 1920 and height to 1080 (or match your canvas size).
- Position the subtitle layer over your scene. It defaults to the lower third — drag to reposition if needed.
- Go live. StreamTranslate listens to your microphone and displays live captions directly on your stream.

Why Subtitles Matter for Twitch Streamers
Twitch's global audience watches in every language — but most Twitch Studio streamers broadcast monolingually. Live captions and translation directly increase your accessible audience. Viewers who are deaf or hard of hearing, watching without audio, or browsing in a second language can now follow your stream without any effort on your part.
Language communities also drive discovery. A translated Spanish caption track means Spanish-language clip sites, Discord servers, and communities can engage with your content. Twitch's own research shows international viewers have strong retention when content is accessible in their language. StreamTranslate handles this automatically — you speak, and your words appear in every language you've configured.

Common Questions
Does Twitch Studio support browser sources?
Yes. Twitch Studio supports browser source layers in scenes, the same way OBS does. You can add any URL as a transparent overlay — which is exactly how StreamTranslate delivers its captions. Any tool that works as an OBS browser source will also work in Twitch Studio.
Will the captions appear on my Twitch VODs?
Yes. Because StreamTranslate renders captions directly into your stream via browser source, they're baked into the video output. They appear in live playback, VODs, clips, and highlights — anywhere the full video is shown.
Can I show translation and original language at the same time?
Yes. StreamTranslate can display two lines simultaneously — your original spoken language on top, and the translated language below. You can also show translation-only if you prefer a cleaner look. Both modes are configurable in your overlay settings.
Does StreamTranslate work if I switch from Twitch Studio to OBS later?
Perfectly. Your overlay URL is the same regardless of what software you use. Copy the same URL into OBS, Streamlabs, XSplit, or any other browser-source-compatible app — it works identically.
What languages does StreamTranslate support?
StreamTranslate supports 30+ languages including Spanish, French, Portuguese, Japanese, Korean, Mandarin, Arabic, Hindi, German, Italian, and more. Unlike Caption.Ninja — which only supports 17 European languages for free and requires you to manage Google Cloud API keys for Asian and MENA languages — StreamTranslate includes all languages in every plan with no API key management.
Is there a free trial?
Yes. StreamTranslate offers a free trial so you can test it live in Twitch Studio before committing to a subscription. No credit card required to start.
