Access: API

Gemini 3.5 Live Translate is a preview model for low-latency speech-to-speech translation. It accepts audio and returns audio rather than treating a general text response as its primary output. Google documents support for more than 70 languages, with output aimed at translated live speech rather than general text reasoning.

The preview endpoint uses the API identifier gemini-3.5-live-translate-preview and returns translated audio plus a text transcript. A separate transcription interface matters only for additional annotations. GPT-Realtime Translate follows a similar speech-to-speech design and also returns transcript deltas.
