Spanish is not a niche language for streaming — it is the second largest audience on the internet and growing faster than English.
English-speaking streamers adding Spanish subtitles can immediately tap into a viewer base that is already watching Twitch and YouTube — they just can't understand the content. One toggle doubles your potential audience.
Spanish-speaking streamers from Mexico, Argentina, Colombia, and Spain are using StreamTranslate to translate their content to English, unlocking the biggest streaming audience in the world without switching languages.
No software to install. No complex configuration. You're live with Spanish subtitles in under five minutes.
Sign up at StreamTranslate and copy your unique browser source URL. Paste it into OBS as a browser source, or load it directly in any streaming software that supports web sources. That's it — no plugins, no SDK.
In your StreamTranslate dashboard, pick Spanish (ES) as your output language. If your stream is already in Spanish, select your source language or enable auto-detect. Both EN→ES and ES→EN are one dropdown selection.
Start your stream normally. Spanish subtitles render on screen in real-time with sub-100ms latency. Your viewers see live captions in español without any extra steps on their end — it just works.
Built for streamers, not enterprise translation departments. Every feature is designed for live gaming and entertainment content.
Subtitles stay in sync with your speech. No awkward 5-second delay that breaks the live feel for your viewers.
Supports both Latin American Spanish dialects (Mexican, Argentine, Colombian, Chilean) and Spain's Castilian Spanish naturally.
Translate from English to Spanish or from Spanish to English — both directions supported with equal accuracy.
Works across every major streaming platform. Single setup, any platform — no separate configurations needed.
Trained on gaming terminology so "respawn", "clutch", "noob", and game-specific terms translate correctly instead of becoming nonsense.
Adjust font size, color, background opacity, and position to match your stream's visual identity.
Pure browser source URL — works in any OBS version, Streamlabs, XSplit, or any software with a browser source feature.
From sign-up to live Spanish subtitles in under five minutes. No API keys to configure, no webhooks, no developer required.

In your dashboard, set the source language (the language you speak on stream — English, Spanish, or auto-detect) and set the target language to Spanish (ES). You can also choose between Latin American Spanish and Castilian Spanish modes in the advanced settings.
StreamTranslate generates a unique browser source URL for your account. Copy it from the dashboard. In OBS, add a new Browser Source — paste the URL, set width to your stream width (e.g., 1920) and height to your stream height (e.g., 1080). Check Shutdown source when not visible and you're done.
Start a test stream or use OBS preview mode — you should see Spanish subtitles appear in real-time as you speak. Adjust caption position and styling in your StreamTranslate dashboard if needed. When it looks right, go live. Your Spanish-speaking viewers will see captions automatically.
Common questions from streamers setting up Spanish translation.
Add Spanish subtitles to your Twitch stream using StreamTranslate's browser source integration. Sign up at streamtranslate.live, copy your unique browser source URL from the dashboard, add it as a Browser Source in OBS or Streamlabs, select Spanish as your target language, and start streaming.

Yes. StreamTranslate handles both Latin American Spanish dialects and Castilian Spanish from Spain. The translation engine understands regional vocabulary differences — for example, "computadora" (LatAm) vs "ordenador" (Spain) — and produces natural, locally-appropriate captions for viewers across all Spanish-speaking regions. You can select your preferred regional variant in the advanced settings, or leave it on automatic to serve all Spanish-speaking viewers equally.
Absolutely — and this is one of StreamTranslate's most popular use cases. Spanish-speaking streamers from Mexico, Argentina, Spain, and Colombia use StreamTranslate to broadcast in their native language while displaying real-time English subtitles for international audiences. This means you can stream authentically in Spanish while opening your channel to the massive English-speaking Twitch and YouTube Live viewer bases simultaneously. No language switching, no separate stream — one setup handles both.
StreamTranslate achieves 95%+ accuracy on gaming content in Spanish. General-purpose translation tools often struggle with gaming terminology — words like "respawn", "noob", "clutch play", "speedrun", or game-specific names end up mistranslated or phonetically approximated. StreamTranslate's translation engine is specifically trained on gaming vocabulary across multiple genres (FPS, RPG, battle royale, MOBA) so these terms are handled correctly in both EN→ES and ES→EN directions. Accuracy is consistently higher than YouTube's auto-captions, which average 70–80% on accented or regional Spanish speech.
Yes. StreamTranslate offers a free tier that gives you access to live Spanish translation without a credit card.
