Quick Answer
To stream in two languages, use StreamTranslate: create a room, set your speaking language and display language, copy the browser source URL, and add it to OBS. Viewers see real-time translated subtitles baked into your stream. You can show your original language alongside a translation.
Why Bilingual Streaming Grows Channels
Bilingual streaming is one of the fastest ways to grow an international audience without creating extra content. Instead of making separate streams for different language communities, you deliver a single broadcast with subtitles that reach both groups simultaneously.
Spanish-speaking audiences represent 500 million potential viewers globally. Portuguese speakers account for another 250 million. Adding translated subtitles to your English stream means your content becomes immediately accessible to both communities.
- Reach Spanish, Portuguese, Korean, Japanese, and Arabic audiences
- Single stream — no extra recording or editing
- Viewers who can read your translations stay longer and follow more
- Works on Twitch, YouTube Live, Kick, X, and TikTok Live
How to Set Up Two-Language Streaming
Step 1: Go to streamtranslate.live/control. Create a room.
Step 2: Set your speaking language (e.g., English). Set the display language to your target audience language (e.g., Spanish).
Step 3: Copy the overlay URL. In OBS, add a Browser Source at 1920x1080.
Step 4: Go live. StreamTranslate generates translated subtitles in real time. Your English-speaking viewers understand you through your voice; your Spanish-speaking viewers read along with the subtitles.
Tip: Announce in your stream title that you have subtitles in the second language. This will show up in browse and attract viewers from that language community.
