Try the Caption Tool FreeNot every caption tool is built with live streaming in mind. Generic transcription software might work fine for recorded videos or podcast post-production, but live streaming demands something different: sub-second latency, resilience to audio quality variations, compatibility with OBS, and the ability to handle the fast-paced, spontaneous speech patterns that define streaming content.
StreamTranslate is built from the ground up for live streaming use cases. Every design decision reflects what streamers actually need: our industry-leading speech AI for the lowest latency and highest accuracy, OBS browser source integration so it drops into any existing setup without replacing your workflow, and multilingual support so the captions you add also expand your potential audience to 125+ language communities.
The OBS browser source integration means StreamTranslate lives inside your existing OBS setup as a transparent layer — you see your captions in OBS preview, you control the positioning and sizing just like any other source, and your captions are baked into your stream without any third-party middleware. Setup takes under five minutes.
Add StreamTranslate as a browser source in OBS. Position, resize, and style captions like any OBS source. No extra software, no API keys to manage.
our industry-leading speech AI understands gaming terminology, character names, game mechanics, and streamer slang. Fewer caption errors means better viewer experience.
Works with Twitch, YouTube Live, Kick, Facebook Gaming, and any other platform you stream to through OBS.
Several tools offer live captions for streamers, but they vary significantly in what they actually deliver. OBS has a built-in captions plugin, but it is English-only, accuracy is mediocre on gaming vocabulary, and there is no translation layer. Windows Speech Recognition can power some caption overlays but requires local processing that adds latency. Google Web Speech API is used by some tools, but it is not designed for streaming latency and does not offer translation.
StreamTranslate uses our industry-leading speech AI — a commercial-grade streaming ASR model designed for real-time applications. The difference in accuracy is measurable, particularly for gaming content where you are using character names, ability names, and game-specific terminology that does not appear in general ASR training data. enterprise speech AI training includes diverse audio sources with much better coverage of gaming vocabulary patterns.
The 125-language translation layer is another major differentiator. No free or built-in caption tool offers real-time translation at this scale. If you want your English Minecraft stream to reach Spanish-speaking viewers, Korean viewers, and Portuguese viewers — you need StreamTranslate. Check our pricing for the right plan.
StreamTranslate combines our industry-leading speech AI accuracy, 125+ language support, OBS browser source integration, and gaming-specific vocabulary training in one tool built specifically for live streamers.
