About LiveKit Agents

LiveKit Agents is an open-source real-time communication framework engineered to build conversational voice, video, and multimodal AI agents with sub-500ms latency. Leveraging WebRTC, it connects speech-to-text (Deepgram, Whisper), LLMs (OpenAI, Anthropic), and text-to-speech (Cartesia, ElevenLabs) in a tightly synchronized bidirectional stream. From customer service avatars to interactive language tutors and hands-free coding copilots, LiveKit Agents provides the enterprise infrastructure for real-time human-AI interaction.

Building real-time voice agents requires solving audio interruption, packet jitter, and latency stacking. LiveKit Agents abstracts these challenges with native Voice Activity Detection (VAD), turn-taking management, and edge-routed audio pipelines. Available in Python and Node.js with client SDKs across React, iOS, Android, and Flutter, LiveKit enables developers to self-host their agent backend or deploy onto LiveKit Cloud.

How It Works

Install the LiveKit Agents SDK and configure your STT, LLM, and TTS providers.

Define agent event handlers for audio stream ingress, user interruptions, and tool calls.

Connect client frontend via LiveKit React or mobile SDK.

Deploy on local servers or auto-scale with LiveKit Cloud.
