Testing & Observability for AI voice agents

Are you building AI voice agents like receptionists, customer support, or sales reps? Do you find yourself manually testing your bot by calling it? We faced similar challenges, especially being in a regulated industry. That's why we developed Cekura - a solution that automates the testing process for your voice agents. With Cekura, you can prove your reliability before going live, test every update seamlessly, and scale your operations efficiently. Replicating a real world conversation is hard. Our AI simulates these scenarios using workflows, personas and past conversations. We are already talking to AI for ordering food, getting appointments and even interviews. The market is aptly getting flooded with AI voice agents built by thousands of companies. We make them dependable.

TL;DR
We were building voice agents in healthcare and spending too much time testing them manually, and they still failed in production due to an edge case. Cekura came out of that experience. We help companies building AI voice agents deploy more reliable bots faster. We test efficiently, identify issues early, and demonstrate reliability before going live—all while enabling rapid development thereafter.

Problem: Anything can go wrong in production

Most teams building in voice, including us, have faced these challenges:

  1. Demonstrating reliability to a client before going live
  2. Manually calling & testing their AI voice agents, which is slow & error-prone.
  3. Identifying all the edge cases in their workflow

Our Solution: Automated evaluations using adversarial voice agents

Run Monte-Carlo-like simulations using curated test sets. Here’s how Vocera helps:

  1. Simulate Conversations: Our AI recreates realistic interactions using a library of workflows and personas.
  2. Replay Old Conversations: Use real voice from painful production calls to run accurate simulations
  3. Automated Scenario Generation: Pass in your call recording, and our AI will generate all the possible scenarios.

Our Ask

if you are building voice agents, we’d love to talk. If you know someone building voice agents, we’d still love to talk.
