Evaluate your Amazon Nova Sonic voice agent at scale, no microphone required
Amazon just open-sourced a tool that lets you evaluate voice agents at scale without hardware. Here's why that matters for your deployment timeline.
Why it matters
Amazon Nova Sonic is gaining infrastructure tooling for production evaluation. The Nova Test Harness removes a key friction point in voice agent development—the need for microphone-based testing—and introduces LLM-as-judge validation at scale, signaling Amazon's push to make voice agents deployable beyond experimental stages.
