Quick Answer
Real-time stream subtitles appear on your live stream as you speak, with under 2 seconds of delay. StreamTranslate uses Deepgram AI to transcribe your speech and translates it live into the viewer's language. Add it to OBS as a browser source — works on Twitch, Kick, and YouTube Live, X, and TikTok.
No GPU. No download. No configuration.
StreamTranslate runs in the cloud — paste one URL into OBS and go live. Works on any laptop or PC. Unlike local AI tools, there's nothing to install or configure.
What Makes Real-Time Stream Subtitles Different?
Traditional subtitle solutions require you to upload recordings after the stream, wait for processing, and manually synchronize the captions. That works for VODs — but live viewers get nothing.
StreamTranslate is built specifically for live streams. It captures your microphone in real time, uses AI to convert speech to text with under 500ms latency, translates the result into your target language, and pushes the subtitle to your OBS overlay immediately. Viewers see the words as you say them — not minutes later.
