# livekit-plugins-cartesia — LiveKit Agents Plugin for Cartesia

License: permissive · Maintenance: active · Downloads: 1.3M/mo

## What it is and what it does

This package provides a plugin that connects Cartesia's voice AI services to the LiveKit Agents framework, enabling real-time speech-to-text and text-to-speech capabilities in video and audio applications. It acts as a bridge between LiveKit's agent orchestration layer and Cartesia's API, allowing developers to build voice-interactive applications without directly managing Cartesia's HTTP endpoints.

The plugin requires a Cartesia API key and integrates as a standard LiveKit Agents component. It supports Python 3.10 and later, and is distributed as a pure Python wheel with a single runtime dependency on livekit-agents. The package is actively maintained and part of the larger LiveKit agents ecosystem.

Use it for:

- Build real-time voice chatbots that transcribe user speech and synthesize responses in live video calls.
- Add voice AI capabilities to LiveKit conference applications for automated transcription and voice commands.
- Create voice-driven interactive agents that listen, process, and speak within a LiveKit session.
- Integrate Cartesia's voice quality into existing LiveKit Agents workflows without custom API management.
- Develop accessibility features that provide real-time speech-to-text and text-to-speech in live meetings.
