Open-source framework for building real-time voice and multimodal AI agents with speech-to-text, LLM processing, and text-to-speech pipelines.
LiveKit Agents Framework is an open-source Python framework for building real-time voice and multimodal AI agents. It provides the complete pipeline for voice-based agent interactions: speech-to-text transcription, LLM processing, text-to-speech synthesis, and real-time audio/video streaming — all integrated into a coherent framework with low-latency performance.
The framework is built on LiveKit's real-time communication infrastructure, which handles the complex networking, codec management, and streaming protocols required for low-latency audio/video. This means developers focus on agent logic rather than WebRTC, audio processing, and network engineering.
API-first platform for building AI phone agents that make and receive calls at scale. Sub-500ms latency, voice cloning, and branching conversation flows for sales, support, and scheduling.
