About Cartesia

Modern voice generation is astonishingly lifelike - but most teams still test those voices the old-fashioned way: one manual call at a time. That slows launches, hides regressions, and lets avoidable issues slip into production.

Today, we’re excited to share our partnership with Cartesia. With this partnership Cartesia’s ultra-realistic, low-latency voices can directly be integrated into Cekura’s automated QA, simulation, and production monitoring platform.
