NovaSynth by Noveum

NovaSynth by Noveum is a self-service platform for automated voice AI testing. It is designed for developers and teams building voice agents who need repeatable ways to exercise conversations before and after changes. Instead of relying only on a person to place each test call, teams can configure synthetic callers, define scenarios and run batches of calls.

A test starts with the caller and the conversation goal. The persona editor supports settings such as tone, speaking speed, interruptions and background noise. These controls let a team represent different calling situations while keeping the intended scenario explicit. A developer can use this configuration to examine how a voice agent behaves when callers speak or interact differently.

NovaSynth supports test calls over phone or LiveKit. After a run, teams can inspect call recordings, transcripts and evaluations. Recordings provide the audible conversation, while transcripts make it easier to inspect the exchange in text. Evaluations help a team review the resulting conversations against its testing needs. The purpose is to make investigation and repeat testing part of the voice agent development workflow.

Batch calls help a team execute several configured tests without manually conducting every conversation. Reusing scenarios after a prompt or application change supports regression checks. Teams can compare observed behavior and investigate calls that need closer attention. NovaSynth is a testing tool for the agent being developed; it does not replace the need to define appropriate scenarios or review the results.

NovaSynth is part of the Noveum platform. Noveum provides a monthly free credit allowance shared across its features, with paid plans available. Voice testing consumes credits, and evaluations can add usage costs. The free allowance is not unlimited voice calling. The official product and pricing pages provide current plan details and the entry points for getting started. The platform is available through the Noveum web application.

What problem it solves

Manual voice agent test calls are difficult to repeat consistently across caller personas and scenarios after application changes. NovaSynth automates batches and supplies recordings, transcripts and evaluations for investigation and regression checks.
