## In short

Continuous translation model that streams a few seconds behind the speaker, auto-detects 70+ languages, and preserves pacing and pitch. Ships across Gemini Live API, AI Studio, Google Meet, and Google Translate today.

## What it is

An audio-native Gemini 3.5 variant focused on live speech translation. Where prior translation tools wait for a sentence to end, Gemini 3.5 Live Translate keeps speaking a few seconds behind the source, auto-detecting the source language from a pool of 70+ and preserving the original speaker's intonation, pacing, and pitch in the output voice.

## How it works

Native end-to-end audio model — no separate ASR, MT, and TTS stack. Detects the source language continuously, generates target-language audio while the speaker is still talking, and watermarks the output with SynthID so the synthetic audio can be detected downstream. A new Android 'listening mode' lets the phone act as a real-time interpreter without prompting.

## Why it matters

Removes the turn-by-turn delay that makes existing translation apps awkward for live meetings, interviews, and travel. Google is wiring it into Meet (2,000+ language combos, up from English-only), Google Translate on Android and iOS, and the Gemini Live API so third parties can build it into agents and call apps.

## Who it's for

Developers building voice agents, Google Meet users, Google Translate users, accessibility teams

## Try it

Public preview via Gemini Live API and Google AI Studio; rolling out in Google Meet and Google Translate
