Summary

An AWS solution demonstrates building a healthcare appointment agent using Amazon Nova 2 Sonic and Amazon Bedrock AgentCore to reduce missed appointments, which average 5–30 percent across US healthcare. This voice agent authenticates patients, manages appointments (confirm, cancel, reschedule), collects pre-visit health information, and escalates to human staff when necessary. Amazon Nova 2 Sonic provides real-time speech-to-speech capabilities, retaining vocal nuances like tone and hesitation, which is crucial in healthcare conversations. Amazon Bedrock AgentCore offers a serverless, scalable runtime for the agent logic. The architecture integrates seven healthcare-specific tools via the Strands Agents SDK, Amazon Cognito for authentication, Amazon DynamoDB for data persistence, and Amazon SNS for notifications, all accessible through a browser-based React frontend for testing.

Key takeaway

For AI Architects designing automated customer service solutions, particularly in healthcare, consider Amazon Nova 2 Sonic with Bedrock AgentCore. This combination allows you to build voice agents that retain vocal nuance and manage complex, multi-step workflows like appointment scheduling and patient information collection. You can significantly reduce no-show rates and operational costs by deploying a scalable, secure, and context-aware conversational AI, freeing human staff for critical tasks. Explore the provided GitHub repository to accelerate your implementation.

Key insights

Amazon Nova 2 Sonic and Bedrock AgentCore enable real-time, context-aware voice agents for complex workflows like healthcare appointment management.

Principles

• Speech-to-speech models preserve vocal context for nuanced AI.
• Tool-calling accuracy is vital for multi-step conversational AI.
• Serverless agent runtimes provide enterprise security and scalability.

Method

The proposed method involves deploying a containerized BidiAgent (Strands Agents SDK) on Amazon Bedrock AgentCore, powered by Amazon Nova 2 Sonic. This agent orchestrates seven healthcare-specific tools via a system prompt, managing authentication, scheduling, and information collection.

In practice

• Implement voice authentication using DynamoDB and GSI.
• Use conditional writes for atomic slot booking.
• Configure SNS for human escalation notifications.
