TTS Providers

TTS plugins convert the agent’s text responses into spoken audio.

Set your API key in .env

Create a .env file (same directory where you run the worker) and add your provider key:

# .env
CARTESIA_API_KEY=...

How to use a TTS plugin

Worker defaults

from dotenv import load_dotenv
from siphon.agent import Agent
from siphon.plugins import cartesia, openai

load_dotenv()

agent = Agent(
    agent_name="Agent-System",
    llm=openai.LLM(),
    tts=cartesia.TTS(),
)

if __name__ == "__main__":
    agent.dev()

Per-call overrides

You can also pass a TTS object into Dispatch(...) or Call(...) for per-call overrides.
