We test AI the way real customers behave.

Trained human testers call your voice agents the way real customers do — impatient, skeptical, off-script — then hand engineering a scored failure map and the fixes to ship first. The same rigor applies to your AI SDRs, chatbots and support AI.

What we evaluate

We evaluate every AI your customers talk to.

Voice is the wedge — the hardest surface to get right. But the operation runs deeper. Each line is scored on its own rubric, validated through the same three-layer QA system, and delivered as a report your engineers can act on.

Voice Agent Testing

Real humans on live calls, finding what only surfaces under interruption, latency, accents, and topic shifts — the failures a text transcript never shows. The fastest, sharpest read on whether your agent holds up with a real caller on the line.

Flagship

Scored on the Voice rubric: intent recognition, accent handling, response accuracy, context retention, conversation quality.

Why AI fails in production

Your AI passed internal tests. Then it met a human.

Internal evals run clean scripts. Real users don't. These are the behaviors that break agents in the wild — and exactly what our testers reproduce on purpose.

» Interrupts mid-sentence» Demands pricing immediately» Switches topic without warning» Asks vague, ambiguous questions» Challenges the agent's credibility» Gives conflicting information» Loops back three turns later» Refuses to follow the happy path
How our evaluation works

Four moves from your AI to a failure map.

01

Human testing

Trained testers run designed scenarios and adversarial conversations against your live agent.

02

Evaluation & scoring

Every interaction is scored on a structured rubric by a separate QA review layer.

03

Failure mapping

We categorize each break — what triggered it, where, and how often it recurs.

04

Recommendations

You get a prioritized, engineer-ready report of what to fix first and why.

Sample findings

What a pilot puts in your hands.

A failure map and a scorecard you can hand straight to engineering — an excerpt of the Conversation Intelligence Report. Below is an illustrative example built to show the format, not a real client result.

What you receive

Outputs from every pilot.

Every finding is ranked by customer impact, how often it recurs, and how cleanly the agent recovers.

Annotated transcripts

Timestamped interactions with reviewer notes and failure markers.

Failure map

Breaks grouped by failure type, frequency, and impact.

Severity-ranked findings

Issues prioritized by business risk and customer impact.

Rubric scores

Consistent scoring across handling, accuracy, flow, and recovery.

Reproduction steps

The exact prompts and conditions needed to recreate each failure.

Prioritized recommendations

Engineer-ready fixes ordered by expected impact.

Supporting evidence — full call recordings and transcripts from every evaluated interaction — is included with each pilot.

Why human testing matters

Internal testing is necessary. Independent testing finds different failures.

Your team knows how the system is supposed to work, so they test the paths it was built for. Our testers don't. They arrive with incomplete information, the wrong assumptions, and the impatience of a real customer — and that distance is exactly what surfaces the failures your own evals never trigger.

  • An external layer, separate from the team that built the agent
  • Adversarial behavior and ambiguity no internal script anticipates
  • Judgment on tone and trust, not just whether the answer was correct
  • Run by an ISO-certified operation with U.S. call-center experience
The assumption gap
CallerYeah, I never got the email. Can you just read me the code over the phone?
AgentOf course — I've sent that to the email on file. Let me know once it arrives.
CallerThere is no email on file. I called from a number you don't have.
Dead end — no path for a caller outside the expected account state
The operation behind the testing

Not a panel of freelancers. A certified evaluation operation.

The evaluation is delivered by KNK Global — an ISO 27001 and ISO 9001-certified, Pakistan-based operation with years of U.S.-facing contact-center experience. English-fluent, trained for conversational-AI evaluation, and structured so scoring is consistent, auditable, and reproducible — not one tester's opinion.

01

Execution

Trained evaluators run the conversations, label every output, tag failure types, and attach a confidence score.

02

Validation

A separate QA layer reviews the work, corrects labeling errors, and checks consistency across evaluators.

03

Authority

A final evaluation authority resolves disputes, locks the scoring rules, and signs off the report before delivery.
