Design patterns for scalable voice agents matter for organizations that need to deliver fast, natural, and reliable voice experiences. Many teams face challenges like high latency, managing real-time audio, and coordinating multiple agents in complex workflows.

In this post, you’ll learn how to use Amazon Nova Sonic, Amazon Bedrock AgentCore, and Strands BidiAgent to build scalable, maintainable voice agents that handle these challenges efficiently, resulting in more responsive and intelligent customer interactions.

We’ll explore three popular architectural patterns for voice agents, highlighting their trade-offs and best practices for minimizing latency.

The building blocks

Before diving deeper into the architecture patterns, here’s a quick overview of the three key components used as the sample solution in this post.
