The Live API enables low-latency, real-time voice and vision interactions with
Gemini. It processes continuous streams of audio, images, and text to deliver
immediate, human-like spoken responses, creating a natural conversational
experience for your users.
Use cases
Live API can be used to build real-time voice agents for a
variety of industries, including:
- E-commerce and retail: Shopping assistants that offer personalized
recommendations and support agents that resolve customer issues. - Gaming: Interactive non-player characters (NPCs), in-game help
assistants, and real-time translation of in-game content. - Next-gen interfaces: Voice- and video-enabled experiences in robotics,
smart glasses, and vehicles. - Healthcare: Health companions for patient support and education.
- Financial services: AI advisors for wealth management and investment
guidance. - Education: AI mentors and learner companions that provide personalized
instruction and feedback. - Translation and localization: Real-time, low-latency translation of
spoken conversations, enabling seamless multilingual communication.
Key features
Live API offers a comprehensive set of features for building
robust voice agents:
- Multilingual support:
Converse in 70 supported languages. - Barge-in:
Users can interrupt the model at any time for responsive interactions. - Tool use:
Integrates tools like function calling and Google Search for dynamic
interactions. - Audio transcriptions:
Provides text transcripts of both user input and model output. - Proactive audio:
Lets you control when the model responds and in what contexts. - Affective dialog:

Technical specifications
The following table outlines the technical specifications for the
Live API:
| Category | Details |
|---|---|
| Input modalities | Audio (raw 16-bit PCM audio, 16kHz, little-endian), images (JPEG <= 1FPS), text |
| Output modalities | Audio (raw 16-bit PCM audio, 24kHz, little-endian) |
| Protocol | Stateful WebSocket connection (WSS) |
Choose an implementation approach
When integrating with Live API, you’ll need to choose one of the following
implementation approaches:
- Server-to-server: Your backend connects to the Live API using
WebSockets. Typically, your client sends stream data (audio, video,
text) to your server, which then forwards it to the Live API. - Client-to-server: Your frontend code connects directly to the Live API
using WebSockets to stream data, bypassing your backend.

Partner integrations
To streamline the development of real-time audio and video apps, you can use
a third-party integration that supports the Gemini Live
API over WebRTC or WebSockets.
