How to Add Translation to IRLToolkit

The 60-Second Setup

You do not need to reconfigure anything in IRLToolkit. You add one browser source to your active scene, paste a URL, and you have live translation running. The total clicks are: log in, add source, paste URL, save. That is it.

StreamTranslate generates a unique overlay URL for your account. That URL is what goes in your browser source. The URL is private to your stream — only your room renders to it. You can put it on multiple scenes if you want captions visible across all your IRL views.

The audio side is handled wherever you currently capture audio. If you have a home PC running desktop OBS as your broadcast machine, that is where StreamTranslate listens for your mic. If you are pure-cloud, you open the StreamTranslate control page in a phone browser tab and grant mic permission there.

Where to Put the Browser Source in Your IRLToolkit Scene

Add the StreamTranslate browser source to whatever scene you want captions visible in. For most IRL streamers that means the main "live" scene — the one with your IRL camera feed. The browser source goes on top of the video source, full-screen, with transparent background so only the caption text shows over your stream.

If you have multiple scenes (a BRB scene, an intro/outro scene, etc.), you can choose whether to render captions on each one. For the BRB and intro scenes most streamers skip captions — for the main live scene, leave them on.

Z-order matters: the StreamTranslate source should sit above your camera feed but below any chat-overlay or alerts overlay you want visible at the top of the screen. Most setups put captions at the bottom-center or bottom-third of the frame.

Translation Output and Language Selection

Pick your spoken language first — usually English for English-speaking streamers. Then pick your target language. For IRL streamers, the recommendation is to target the language of the audience you want to grow: Spanish for LATAM viewers, Portuguese for Brazilian viewers, Japanese for Japanese viewers, Korean for Korean viewers.

You can switch the target language at any time from your control panel without restarting your stream. The overlay updates without any IRLToolkit-side change. This is useful when you cross borders during a stream — Mexico to the US, Singapore to Malaysia, etc.

For maximum reach without picking one specific audience, the Twitch Extension version of StreamTranslate lets each viewer choose their own language. The overlay shows captions in whatever language each individual viewer picked. That is the configuration that works best for IRL streamers with truly global audiences.
