Build a real-time voice agent with Gemini & ADK

Building advanced conversational AI has moved well beyond text.

Now, we can use AI to create real-time, voice-driven agents. However, these systems need low-latency, two-way communication, real-time information retrieval, and the ability to handle complex tasks. This guide shows you how to build one using Gemini and the Google Agent Development Kit (ADK). You’ll learn how to create an intelligent, responsive voice agent.

The foundational agent

First, we create an agent with a persona but no access to external tools. This is the simplest agent, relying only on its pre-trained knowledge. It’s a great starting point.
