Voice AI agent cost calculator: AI phone agent vs call-centre staff

A voice AI agent is usually priced per minute of conversation, covering speech recognition, the language model, text-to-speech and telephony. A human call centre costs agents’ paid hours, including time between calls and after-call work. Compare them per call: AI cost = minutes × AI rate; human cost = (talk + wrap-up minutes) ÷ occupancy × hourly cost. Calls the AI cannot finish are transferred to a person.

What makes up the per-minute price

ComponentRole
Speech-to-text Transcribes what the caller says in real time
Language model Understands intent and decides what to say or do
Text-to-speech Speaks the reply in a natural voice
Telephony Phone numbers and call minutes
Orchestration platform Handles turn-taking, interruptions, transfers and integrations

Getting it right

  1. Start with one or two call types that follow a clear script.
  2. Connect the agent to your calendar, CRM or order system so it can act, not just talk.
  3. Always offer a quick route to a person.
  4. Disclose that callers are speaking to an AI where required, and follow call-recording rules.
  5. Review transcripts weekly to improve prompts and answers.
