Define a Conversation Flow with SignalWire AI Agent

Building Smarter Virtual Assistants with SiganlWire's New AI Agent Builder

Creating a smart, responsive voice agent no longer requires complex infrastructure or hours of coding. In this episode of SignalWire in Seconds, Technical Success Manager Nicholas walks through the updated AI Agent Builder, which makes it even easier to create powerful, dynamic AI agents for real-time customer interactions.

What’s New in the AI Agent Builder?

This second iteration builds on the original release by offering a simplified, guided workflow that enables users to:

• Define an agent’s name, personality, and tone

• Choose from a range of natural-sounding voices powered by Amazon Polly, Google Cloud, or ElevenLabs

• Add custom skills and behaviors through fill-in-the-blank modules

• Set hours of operation, transfer calls to live reps, and inject custom knowledge (like amenities at a resort)

• Design full conversational flows using plain text instructions, formatted with markdown behind the scenes

All of this happens inside the SignalWire dashboard, without the need to manage servers or webhooks.

A Real-World Example: Gustav, the Virtual Concierge

To demonstrate, Nicholas builds “Gustav,” a friendly virtual concierge for a ski resort. Gustav can:

• Greet guests in a warm, natural voice

• Share lobby hours, resort amenities, and spa offerings

• Transfer callers to booking or excursions

• Play background music while fetching data

• Disconnect idle calls after a customizable timeout

By the end of the video, Gustav is live and ready to help guests enjoy their stay—entirely powered by SignalWire’s AI tooling and real-time APIs.
