How to use this calculator

What this calculator does

Estimate the full monthly cost of an AI voice assistant, including speech recognition, speech synthesis, telephony, language-model calls and fixed infrastructure.

How to use it

Count billable voice calls and their measured duration. Use the actual per-minute rates for speech-to-text, text-to-speech and telephony plus the model spend per call. Include fixed hosting even if the agent receives no calls.

What the result means

Compare the voice cost per conversation with call-resolution quality and cost of escalation to a person; the estimate does not account for how many callers get an acceptable answer.

Actual AI costs depend on provider pricing, model choice, token usage, discounts, caching, retries, batching, tool calls, workflow design, and usage volume.

Scenario guidance

When to use this

Use for inbound voice assistants and customer-service phone agents.

Example scenario

An appointment service handles 5,000 AI-assisted calls each month.

Inputs that usually matter most

  • Average billable conversation minutes
  • Separate speech, telephony and model prices

Common mistake to avoid

Do not count the model per-call estimate again within the per-minute charges.

How to interpret the result

Review call resolution, escalation to staff and time spent on hold.

Prices, limits, service quality and billing rules differ by provider. Confirm all rates and measurable outcomes.

Formula

Monthly cost = calls × [minutes × (recognition + synthesis + telephony rate) + model cost per call] + monthly platform fee.

Assumes recognition, synthesis and telephony use all minutes of every call; partial voice activity or minimum-minute billing may change charges. Model spending is entered separately per conversation.

Worked cost example

Five thousand four-minute calls at $0.006 ASR, $0.016 TTS, and $0.02 telephony per minute plus $0.03 model cost per call and $100 platform overhead total $1,090 each month.

Frequently Asked Questions

Why charge speech recognition and synthesis separately?

A spoken assistant may pay separately to understand the caller and to generate the spoken response. Vendor bundles may combine these; enter only charges actually billed.

Are human handoffs included?

No. Add the labor and other tools used by escalated calls in a separate estimate.
