A voice travel concierge combines streaming speech, agent tools and managed retrieval

aws.amazon.com by Ravi Kumar 12 min read Editor score 7/10

The design uses Nova Sonic for real-time speech, AgentCore for the agent and Knowledge Bases for document retrieval, while addressing multi-turn conversations and backend integration. It illustrates the components and integration concerns of a production voice agent.

What
A voice travel concierge lets airline customers use spoken requests to manage tasks such as seat changes, flight-delay checks, and policy questions.
How
Nova Sonic handles real-time speech, AgentCore runtime hosts the agent, and AgentCore Gateway exposes backend services as MCP tools.
Why it matters
Separating the front end, agent, and backend services with MCP keeps them loosely coupled and lets each layer scale independently.
