Quick Answer
Live translation is the real-time conversion of spoken language into translated text or subtitles. StreamTranslate provides live translation specifically for streamers — supporting 28+ languages with under 2-second latency via an OBS Browser Source overlay.
What Is Live Translation?
Live translation (also called real-time translation) is the process of converting spoken language into another language as it happens. Unlike pre-recorded subtitles, live translation works in real time — the speaker talks, and translated text appears within seconds.
Live translation is used in conferences, events, meetings, and increasingly in live streaming. For streamers, it means international viewers can follow your content in their language.
How Live Translation Works for Streamers
StreamTranslate uses a three-step pipeline for live translation:
- Step 1: Transcription — Deepgram AI listens to your microphone and converts speech to text in real time.
- Step 2: Translation — Google Translate converts the transcribed text into your chosen target languages.
- Step 3: Display — Translated subtitles render on an OBS Browser Source overlay that appears on your stream.
The entire process takes under 2 seconds from speech to translated subtitle.
