Real-Time Voice Interactions with the WebSocket Audio Adapter

Realtime agent communication over websocket

TL;DR: - Demo implementation: Implement a website using websockets and communicate using voice with the RealtimeAgent - Introducing WebSocketAudioAdapter: Stream audio directly from your browser using WebSockets. - Simplified Development: Connect to real-time agents quickly and effortlessly with minimal setup.

Realtime over WebSockets

In our previous blog post, we introduced a way to interact with the RealtimeAgent using TwilioAudioAdapter. While effective, this approach required a setup-intensive process involving Twilio integration, account configuration, number forwarding, and other complexities. Today, we're excited to introduce theWebSocketAudioAdapter, a streamlined approach to real-time audio streaming directly via a web browser.

This post explores the features, benefits, and implementation of the WebSocketAudioAdapter, showing how it transforms the way we connect with real-time agents.

Tools Dependency Injection

Dependency Injection is a secure way to connect external functions to agents without exposing sensitive data such as passwords, tokens, or personal information. This approach ensures that sensitive information remains protected while still allowing agents to perform their tasks effectively, even when working with large language models (LLMs).

In this guide, we’ll explore how to build secure workflows that handle sensitive data safely.

As an example, we’ll create an agent that retrieves user's account balance. The best part is that sensitive data like username and password are never shared with the LLM. Instead, it’s securely injected directly into the function at runtime, keeping it safe while maintaining seamless functionality.

Why Dependency Injection Is Essential

Here’s why dependency injection is a game-changer for secure LLM workflows:

  • Enhanced Security: Your sensitive data is never directly exposed to the LLM.
  • Simplified Development: Secure data can be seamlessly accessed by functions without requiring complex configurations.
  • Unmatched Flexibility: It supports safe integration of diverse workflows, allowing you to scale and adapt with ease.

In this guide, we’ll explore how to set up dependency injection and build secure workflows. Let’s dive in!
