AI voice · pricingThe cheapest voice AI price is often a data-sharing discountThe number at the top of a voice AI pricing page is often the discounted one. Two tricks recur: a lower rate you get only by letting the vendor train on your audio, and a promo price parked where the standing price belongs. Here is how to read past both, with the dated captures that caught them.2026-07-24 · 9 min read AI voice · pricingAI receptionist vs human: the real cost mathsEvery blog ranking AI receptionists claims a saving of 93 to 95 per cent, built on a human baseline padded with recruitment, training, turnover write-offs, even the desk and computer. We redo the maths with statutory numbers only (BLS and IRS for the US, ONS and gov.uk for the UK) and set them against our dated AI pricing.2026-07-12 · 9 min read AI voice · pricingWhat an AI voice agent really costs per minuteThe advertised per-minute rate is usually a floor, not a bill.
