Build Your First AI Voice Agent

Voice is becoming one of the most exciting ways to interact with AI. Instead of typing prompts, users can have natural, real-time conversations with intelligent assistants that can listen, think, call external tools, and respond instantly.
In this hands-on remote meetup,

Rather than focusing on theory or frameworks, we'll build the application step by step and understand how real-time voice interactions work under the hood.
By the end of the session, you'll have a voice assistant that can:

• Listen to spoken input in real time
• Respond with natural AI-generated speech
• Call external APIs using AI tool/function calling
• Maintain conversational context throughout the interaction

What You'll Learn

• How modern AI voice agents work
• Setting up a realtime voice session with GPT Realtime API
• Capturing microphone audio in the browser
• Streaming audio and AI responses
• Understanding realtime events
• AI tool/function calling
• Integrating a third-party API
• Prompt engineering for voice applications

Tech Stack

• Python
• FastAPI
• HTML & Vanilla JavaScript
• GPT Realtime API

Who Should Attend?

This meetup is ideal for:

• Software engineers
• Backend and frontend developers
• Python developers
• AI enthusiasts with programming experience

Basic knowledge of Python and JavaScript is recommended. No prior experience with AI is required.

Format

• Remote live coding session
• Follow along on your own laptop
• Interactive Q&A throughout the session

The focus is on building, not watching. We'll write code together, explain each step, and leave you with a complete working project that you can continue experimenting with after the meetup.
