Start Transcribing Your StreamLive stream transcription is fundamentally different from transcribing a recorded video. When you are live, there is no second take, no editing pass, no opportunity to clean up what was said before it reaches your audience. The transcription engine needs to process audio in real time, handle the natural patterns of live speech — filler words, sentence restarts, streamer slang — and deliver text that is readable within seconds.
StreamTranslate is built on our industry-leading speech AI, a streaming ASR model purpose-built for real-time audio. Unlike general-purpose transcription APIs that batch audio and return results after a delay, enterprise speech AI processes your audio stream continuously and returns transcription results as you speak. The typical latency is under 500 milliseconds between you saying something and the caption appearing on screen.
This real-time transcription powers everything else in StreamTranslate: the live captions your viewers see, the multilingual translations that expand your global audience, and the text transcript you can export and repurpose after your stream ends.
The same streaming ASR used by enterprise applications. enterprise speech AI delivers sub-500ms latency and 95%+ word accuracy for live stream audio.
Transcribe in your native language and StreamTranslate automatically translates to 125+ target languages in real time.
Add StreamTranslate as an OBS browser source. Your transcription appears as an on-stream caption overlay without any additional software.
For multilingual streamers, transcription is only the first step. Once StreamTranslate has an accurate transcription of what you are saying, it feeds that text into a real-time translation pipeline that converts your words into 125+ other languages simultaneously. Your English commentary becomes Spanish captions for your Latin American viewers, Japanese captions for your Asia-Pacific audience, and Portuguese captions for your Brazilian fans — all at the same time, all from a single transcription pipeline.
The accuracy of this multilingual output depends entirely on the quality of the initial transcription. A transcription error at the enterprise speech AI level propagates into every translated language. That is why we use our industry-leading speech AI specifically — its accuracy on live, spontaneous speech is significantly better than what you would get from general-purpose transcription APIs. For streamers who want their translated captions to actually make sense to international viewers, starting with the most accurate transcription available is essential.
