LiveKit Agents is an end-to-end framework that enables developers to construct intelligent multimodal voice assistants (AI agents) that interact with users via voice, video, and data channels. It provides a quick-start guide for creating voice assistants by integrating OpenAI's real-time API and LiveKit's WebRTC infrastructure, including pipelines for speech-to-text (STT), language models (LLM), and text-to-speech (TTS). Additionally, it supports building voice-to-voice agents, handling incoming calls, and making calls on behalf of users.
