This tutorial outlines the process of building a real-time AI voice agent using AssemblyAI for speech-to-text conversion, DeepSeek R1 via Ollama for generating intelligent responses, and ElevenLabs for text-to-speech synthesis. These AI voice agents are increasingly used in customer interactions, improving efficiency and experience by surpassing human performance in certain tasks. The guide details setting up the system, including installing dependencies and configuring the AI agent, allowing developers to create applications that facilitate seamless, interactive voice-based communication. By the end of the tutorial, learners will have constructed a fully functional AI voice agent capable of transcribing, processing, and responding to spoken queries in real time.
