Gemini 3.5 Live Translate
Gemini 3.5 Live Translate is Google’s near real-time speech translation model for developers, Google Meet, and the Google Translate app. It supports 70+ languages and is designed to produce natural-sounding translated audio during live conversations.
What Gemini 3.5 Live Translate does
Gemini 3.5 Live Translate is Google’s audio model for live speech-to-speech translation. It detects more than 70 languages, processes speech as it is streamed, and generates translated audio that stays close to the speaker in near real time.
Google is rolling out the model across three product surfaces: developers can access it through the Gemini Live API and Google AI Studio, enterprises can use it in private preview in Google Meet, and consumers can use it in the Google Translate app on Android and iOS. The model is aimed at live interpretation scenarios where low latency, natural voice output, and multilingual conversation matter.
Key capabilities
Near real-time speech-to-speech translation
Instead of waiting for a full turn to finish, the model translates continuously and stays only a few seconds behind the speaker, helping conversations sound more natural.
Natural-sounding voice output
Google says the translated voice preserves the speaker’s intonation, pacing, and pitch, which helps the output sound closer to the original delivery.
Streaming and noise robustness
The model is designed to handle streamed speech and noisy, unpredictable environments, making it suitable for live calls, meetings, lessons, and broadcasts.
Developer access through Gemini Live API
Google says the model can be used through the Gemini Live API and Google AI Studio, and that partners such as Agora, Fishjam, LiveKit, Pipecat, and Vision Agents use those APIs to build voice translation apps.
SynthID watermarking
Google says all generated audio is watermarked with SynthID so AI-generated speech remains detectable.
Where it fits
Multilingual live conversations
Use the model for live interpretation when two or more speakers need to keep talking naturally across language barriers, such as interviews, calls, or cross-border conversations.
Business meetings in Google Meet
Teams running meetings in Google Workspace can use the Meet integration for speech translation during business calls, with access described as private preview at launch.
Custom translation apps
Developers can build voice translation experiences in Google AI Studio or through the Gemini Live API, including apps that plug into real-time media infrastructure.
Mobile translation in the Translate app
People using the Google Translate app on Android or iOS can use Live translate for more seamless translation on the go, including headphones-based listening and Android earpiece mode.
Live audio sessions in public or noisy settings
The model is suitable for settings such as lessons, broadcasts, and noisy environments where streaming translation and low latency matter more than turn-based transcription.
