Build a Real-Time Voice AI Assistant with Twilio's ConversationRelay, LiteLLM, and Python

This tutorial aims to help developers build a real-time voice AI assistant using Twilio's ConversationRelay and LiteLLM, allowing for quick integration with multiple large language model (LLM) providers. The setup features real-time streaming responses via a WebSocket server, multi-provider LLM support, smoother voice interactions, and straightforward Twilio Voice integration through ConversationRelay. To get started, developers need to have Python 3.8+, API keys for the chosen LLM provider, ngrok for exposing the test server to Twilio, a Twilio account and registered phone number, and follow specific installation steps to configure the server and connect it with Twilio Voice using ConversationRelay.
