LiveKit + Cartesia Python Voice Agent

Deploy a sandbox app • LiveKit Agents Docs • LiveKit Cloud • Blog

A basic example of a voice agent using LiveKit with Cartesia.

Dev Setup

Clone the repository and install dependencies to a virtual environment:

cd cartesia-livekit-voice-agent
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Set up the environment by copying .env.example to .env.local and filling in the required values:

• LIVEKIT_URL
• LIVEKIT_API_KEY
• LIVEKIT_API_SECRET
• OPENAI_API_KEY
• CARTESIA_API_KEY
• DEEPGRAM_API_KEY

You can also do this automatically using the LiveKit CLI:

lk app env

Run the agent:

python3 agent.py dev

This agent requires a frontend application to communicate with. You can use one of our example frontends in livekit-examples, create your own following one of our client quickstarts, or test instantly against one of our hosted Sandbox frontends.
