Getting Started

Building your first voice agent in Python on the Syllable SDK is fast, flexible, and designed to scale. Browse our tutorials for more walkthroughs. In this guide, we'll walk through how to spin up an intelligent agent in just a few minutes using Python.

The SDK gives developers full control over the agent-building process, from defining behavior and personality to connecting live data sources and external tools.

Why use the SDK?

If you've explored the Syllable Console, you know how easy it is to configure agents in a no-code environment. The SDK offers the same power, but with developer flexibility:

• Automate agent creation and updates
• Programmatically define prompts, tools, and messages
• Integrate with your existing infrastructure and CI/CD pipelines

The SDK is ideal if you're building deeply integrated systems and need the power of programmatic control. Visit the Python SDK on GitHub.

Tutorial Overview

The full tutorial walks through these steps:

• Environment Setup — Install the Python SDK with pip install syllable-sdk
• Add a Data Source — Create a static knowledge base for your agent
• Define Tools — Create tools that call external APIs or search data sources
• Create a Message — Define your agent's greeting
• Create a Prompt — Define the agent's personality, capabilities, and boundaries
• Assemble Your Agent — Put all the pieces together
• Test and Iterate — Test in the Syllable Console and refine

What's Next

• Find the Python Agents SDK Documentation on GitHub
• Add more tools and connect real-time systems with your agent
• Build a pipeline to manage multiple agents with ease
