Coval

Coval is a voice AI testing and evaluation platform that lets teams simulate realistic conversations before launch, monitor production performance, and route problematic calls to human reviewers, feeding insights from each stage back into the next testing cycle. It's used by product, QA, operations, and compliance teams deploying voice agents in customer support, financial services, healthcare, and travel, sitting as a testing and monitoring layer on top of voice agent platforms and frameworks like LiveKit or Pipecat.
