In a bold move that brings AI voice technology closer to mainstream development, SignalWire—the company behind Programmable Unified Communications (PUC)—has partnered with Amazon Web Services (AWS) to integrate AWS’s cutting-edge Nova Sonic voice-to-voice AI model into the SignalWire platform.

This collaboration promises to streamline the development of conversational voice apps, enabling devs to bypass telecom complexity and focus on building intelligent, human-like voice interactions.

Nova Sonic Now Speaks SWML

At the core of this integration is the introduction of a powerful new SWML (SignalWire Markup Language) verb, aptly named amazon_bedrock, which bridges AWS Nova Sonic with SignalWire’s programmable infrastructure.

With full compatibility with SignalWire's SDK, developers now have a plug-and-play way to incorporate Nova Sonic’s highly responsive, human-sounding conversational AI into any voice app, IVR system, or contact center solution.

And it’s not just about voice prompts and canned replies—Nova Sonic delivers dynamic, context-aware responses, giving developers access to the kind of fluid, back-and-forth conversations typically reserved for high-end enterprise AI systems.

Going Beyond the Basics

But this partnership isn’t stopping at voice quality.

Through SignalWire’s AI Gateway, developers can connect voice AI agents to external services, like customer support platforms, databases, or CRMs—allowing Nova Sonic-powered voice agents to look up orders, open service tickets, or execute real-time tasks during a call.

Think of it as giving voicebots not just a brain, but hands to get things done.

No-Code Agent Builder = Faster Prototyping

SignalWire also announced support for Nova Sonic in its open source Agent Builder, a visual, no-code tool hosted on GitHub that lets teams design voice agents without writing code.

The Agent Builder generates SWML configurations automatically, making it easier for developers and non-devs alike to prototype, test, and deploy voice applications within hours instead of weeks.

This fits neatly into a broader trend: companies racing to give more people access to AI tools—without needing deep dev experience or knowledge of telecom APIs.

The integration of AWS Nova Sonic with SignalWire’s PUC platform unlocks serious potential for contact centers, virtual assistants, and real-time service applications.

“This opens a new frontier of possibilities for developers and businesses alike,” said Anthony Minessale, CEO and co-founder of SignalWire. “By baking Nova Sonic into our SWML and open source tools, we’re making it easy to build intelligent voice experiences—without wrestling with legacy telecom hurdles.”

In a market increasingly shaped by real-time, AI-fueled interactions, SignalWire’s developer-first, open ecosystem approach could be a blueprint for the future of voice communications.
