The most expensive failures in voice AI are silent. The agent hears "March 15th" as "March 50th." It captures "123 Main Street" instead of "132 Main Street." It places the order, books the appointment, processes the payment, and the caller doesn't find out something went wrong until later. Coval tests whether your agent confirms key details before it commits.
Get StartedWe score each transcript against the confirmation rules for your context.
We also run the edge cases that catch agents off guard: an agent that says "Done!" before the caller finishes their thought fails the same way as one that never confirms at all.
Tell Coval what your agent does. We generate confirmation scenarios for that action, run simulated calls, and check whether the agent read back the right details, waited for the right consent, and handled corrections cleanly.
Defaults are calibrated by industry. A QSR order confirms differently from a wire transfer; a medical appointment differently from a return.
Make sure your agent confirms who it’s talking to before it shares information or takes action.
