Affordability in voice automation is cost-per-booking plus hidden overhead, not sticker price alone. Most platforms advertise $0.05 to $0.35 per minute[1], but that rate covers only platform orchestration — the full stack includes voice generation (TTS), speech recognition (STT), language understanding (LLM), telephony, and infrastructure, each billed separately[1]. For appointment scheduling specifically, calendar integration, automated reminders, and 24/7 coverage shift the affordability calculation: the cheapest per-minute platform may not be the most affordable if it lacks these workflow essentials.
