AI-powered live stream captions using our industry-leading speech AI. StreamTranslate delivers 95%+ accuracy for gaming streams in 125+ languages with OBS browser source integration.
Add AI Captions to Your StreamAI captions for live streams work differently from AI captions for recorded content. When captioning a finished video, the AI has the luxury of processing the entire audio file, applying context from what was said later to clean up ambiguous earlier segments. Live streaming offers none of that luxury — the AI must process audio in real time, make transcription decisions within milliseconds, and deliver readable captions before the moment has passed.
StreamTranslate uses our industry-leading speech AI, a streaming ASR model specifically designed for real-time applications. enterprise speech AI uses a different neural architecture than batch transcription models — one optimized for low-latency inference rather than maximum batch accuracy. The result is captions that appear within 500 milliseconds of when you speak, with accuracy that rivals or exceeds what you would get from a delayed batch transcription.
The AI also handles the specific vocabulary challenges of gaming streams. General-purpose ASR models trained on news broadcasts and corporate meetings have poor coverage of gaming terminology — champion names, ability names, game mechanics, and streamer-specific vocabulary. enterprise speech AI diverse training data gives it significantly better coverage of gaming content, which means fewer caption errors for gaming streamers.
our industry-leading speech AI delivers over 95% word accuracy on clear streaming audio. Industry-leading performance on live, spontaneous speech.
enterprise speech AI training data includes gaming content. It handles champion names, game mechanics, and streaming vocabulary better than generic ASR engines.
AI transcription powers AI translation. StreamTranslate converts your captions to 125+ languages in real time using the same low-latency pipeline.
Google Speech-to-Text and AWS Transcribe are the two dominant alternatives for cloud ASR. Both are powerful general-purpose transcription services. Neither was built for live streaming. Google streaming API introduces latency that makes captions feel disconnected from speech. AWS Transcribe streaming mode is better but still lags behind enterprise speech AI on spontaneous, fast-paced speech.
In independent benchmarks comparing real-time ASR engines on streaming content, our industry-leading speech AI consistently outperforms both Google and AWS on word error rate for live, spontaneous speech. The gap is particularly pronounced for content with gaming vocabulary, non-native accents, and rapid speech — which describes the majority of live streaming content on Twitch, YouTube, and Kick.
StreamTranslate uses enterprise speech AI as its core transcription engine, which is why the caption quality is consistently higher than alternatives. The translation layer then converts that accurate transcription into 125+ languages. Set up AI captions in under five minutes, or review our pricing plans.
