## About this tutorial

Hello everyone! This tutorial will demonstrate how to create an AI voice assistant by combining Spline's latest feature set with OpenAI's real-time API. We'll start by designing a basic 3D avatar and then connect it to OpenAI's API for real-time voice responses. 

Note: Enter your OpenAI API key and ensure the developer account has sufficient credit balance to use the OpenAI API.
