What is LiveKit?

LiveKit is a realtime framework for building production-grade multimodal and voice AI agents. It enables Python or Node.js programs to participate as full participants in LiveKit rooms, processing realtime audio, video, and data streams with WebRTC reliability. LiveKit has a built-in LMNT integration that makes it easy to create high-performance voice AI agents with LMNT voices. The integration is optimized for realtime voice applications and supports voice clones, multilingual speech, and low-latency streaming.
