Buyer's evaluation guide
Every AI receptionist demos well. What separates a production system is latency, real telephony, honest pricing, bilingual support, and measurable quality. Here is how to judge one, and where NuTalk lands.
For buyers comparing AI receptionists who want criteria, not a ranking they cannot verify.
Call it, interrupt it, and see whether the conversation stays natural.
Confirm it runs on a real line and whether calls are metered.
Ask how the system measures call quality after deployment, not just before.
Realtime
latency
The first thing to test on any AI receptionist.
Flat
pricing
A flat plan beats per-minute on a busy month; check its fair-use terms.
Evals
built in
Quality you can measure, not just claim.
/01
A polished sales call is not proof. Judge an AI receptionist on how it behaves under real load, on a real line, over time.
