This project is an AI-powered voice assistant integrating Twilio and OpenAI to create a dynamic, conversational interface. The system leverages Twilio to handle real-time calls and transcribing speech, then routes the transcription to OpenAI's language model to generate context-aware responses. The result is an end-to-end solution that seamlessly combines telephony with advanced conversational logic for an interactive voice experience.
