Voice AI

A voice agent that passes in a studio can still fail its first real caller

Recognition degrades on dialect and on telephone audio. The dialogue manager then works from a degraded transcript, asks the caller to repeat themselves, and the caller speaks faster and less clearly. Each part may be acceptable alone and the system still unusable.

Scenarios

What we test against

Telecom support

Outages, plan changes, credit transfers — the calls that dominate real volume.

Banking

Balances, transfers, card problems, branch and payment questions.

Travel

Bookings, schedules, changes and cancellations.

E-commerce

Order status, returns, delivery to regions far from the capital.

Public services

Documents, appointments and administrative procedures.

General customer support

Complaints, escalations and callers who are already annoyed.

Dimensions

What we score

We score the call, not the transcript. A system can produce a clean transcript and still leave the caller without an answer.

Intent understanding

Did the agent work out what the caller wanted?

Dialect comprehension

Did it cope with the variety and the speed the caller actually used?

Speech recognition

Measured on telephone-band audio, not studio recordings.

Response relevance

Was the answer about the caller's problem?

Pronunciation

Is the synthesised voice intelligible and locally plausible?

Naturalness

Does the exchange feel like a conversation or an interrogation?

Latency

Measured as the caller experiences it, including think time.

Task completion

Did the caller end the call with what they rang for?

Safety

What the agent does when it is out of its depth.

Why it has to be people

Synthetic test audio does not reproduce the speed, reduction and code-switching of a real caller, and it never becomes impatient. We test with native speakers running realistic scenarios, on real calls.
