# Google launches Gemini 3.5 Live Translate, voice-preserving real-time speech translation in 70+ languages

On 2026-06-09 Google released Gemini 3.5 Live Translate, an audio-to-audio model that translates speech continuously a few seconds behind the speaker while preserving their intonation, pacing and pitch. It auto-detects 70+ languages, ships in the Gemini Live API (preview), Google Translate on Android/iOS and Google Meet (private preview, 5 to 70+ languages).

## Key facts
- Model id gemini-3.5-live-translate-preview; ~$0.0053/min audio in, ~$0.0315/min audio out
- 70+ languages auto-detected; 2,000+ language combinations in one meeting
- Continuous (not turn-by-turn) output, streamed in 100 ms chunks (press); SynthID watermark on outputs
- Model card 'Gemini 3.5 Audio' (dated 2026-08-26, also covers Transcribe/Transcribe Live): no numeric evals in the card; knowledge cutoff Jan 2025; no Frontier Safety Framework Tracked or Critical Capability Level reached; limitations include inconsistent voices and weak detection of non-native accents and rapid language switching
- Google Translate app gains a headphone 'listening mode'; early testers include Grab, CJ ENM and LiveKit

## What happened

Google introduced a dedicated live speech-translation model and rolled it into consumer (Translate), enterprise (Meet) and
developer (Live API) surfaces at once.

## Why it matters

Voice-preserving simultaneous interpretation moved from demos into products used by hundreds of millions of people,
competing directly with OpenAI's gpt-realtime-translate released a month earlier.
