What does it actually cost to test a voice bot?

Voice bot testing costs roughly $0.07 to $0.50 per call minute depending on what you're testing. For a typical agentic IVR with one daily regression suite and a quarterly load test, expect $50–$500/month on a self-serve platform like TotalPath. The same coverage on a legacy enterprise vendor (Cyara, Hammer) typically lands as a five-figure annual contract with a separate professional services engagement.

The reason is that voice testing is one of the few SaaS categories where the underlying cost (real PSTN minutes, ASR, TTS, LLM tokens) is small but real. Most of the price on enterprise platforms is the sales motion, the implementation services, and the assumption that you'll commit annually. Strip those out and the floor is much lower than most teams realise.

This post is the honest breakdown.

The four cost components

Every voice test has the same four cost components. Vendors price each one differently.

Call minutes (PSTN cost). Every test is a real phone call. Termination over PSTN costs roughly $0.005 to $0.02 per minute at wholesale, depending on the destination country. Premium-rate or international destinations cost more. A vendor passing this through fairly should land at the low end of the per-minute test rate.

ASR (speech recognition). Recognising what the bot says back, so the test caller can react. Around $0.01 to $0.04 per minute at wholesale (Deepgram, Google, AssemblyAI etc.).

TTS (the test caller's voice). Generating the test caller's audio. Modern TTS is cheap — under $0.01 per minute for streaming output.

LLM tokens (for agentic test callers). If the test caller is an LLM-driven agent rather than a deterministic script, there's an LLM bill on top. Roughly 1,000–3,000 tokens per minute of conversation, or about $0.005 to $0.05 per minute depending on the model.

Add that up: real wholesale cost is roughly $0.03 to $0.10 per call minute. A fair retail price for managed voice testing is roughly 2–3x that, which is where TotalPath sits.

TotalPath pricing in numbers

We publish all of this. A few common scenarios.

A daily regression suite of 20 test calls, 90 seconds each. That's 30 minutes a day, 900 minutes a month. The free tier covers 25 minutes of testing a month, so this lands on the Starter plan: $49/month subscription plus $0.080/min × 875 paid minutes ≈ $119/month all in.

The same suite plus a monthly 50-call load test, each call 30 seconds. Adds 25 load-testing minutes/month at $0.070/min ≈ $1.75. Negligible. Still $121/month all in.

A quarterly capacity validation at 100 concurrent calls for 30 seconds. That's 50 minutes of load-testing one weekend a quarter. About $3.50 per quarter. The free tier's load-testing allowance (75 min/month) covers this on its own.

A regulated team running compliance attestation across 50 numbers monthly, 5 tests per number. 250 calls × 60 seconds = 250 minutes of testing a month. On the Team plan: $499/month subscription + $0.080/min × 225 paid minutes ≈ $517/month all in.

The headline: most teams running serious voice testing on TotalPath are between $50 and $500 a month all in. The free tier covers most teams who are just getting started.

What enterprise vendors charge

Cyara and Hammer don't publish pricing. We can give industry-typical figures from procurement teams who've shared them.

A starter Cyara contract — Velocity for IVR testing only, no Cruncher, no Botium — typically lands in the $30,000–$60,000 annual range for a small estate, plus a one-off implementation fee in the same range. Add Cruncher (load) and you're past $80,000. Add Botium (chatbot) and you're past $120,000. Multi-year discounts apply if you commit.

Hammer is in a similar bracket. Mid-six-figures annually for a meaningful regulated estate is normal. Both come with a professional services bench you'll be using.

These are not unreasonable prices for what they deliver. They are the wrong shape for a team that wants to start testing this week.

When the enterprise number is the right number

To be honest about it, sometimes it is.

If you operate at the scale where one outage is a six-figure regulatory fine, a Cyara contract is cheaper than the fine. If your CX assurance programme spans voice plus chat plus web plus social and you want one auditor's report for all four, a single vendor across all four is operationally simpler. If you have an existing professional services relationship that's working, replacing the tool to save $10k a month while burning $200k of internal time is a bad trade.

Most teams aren't in those situations. Most teams are running a contact centre that needs to ship more reliably, and the legacy contract is overkill.

What we recommend if you're starting from scratch

Start on the free tier. 130 minutes a month. No credit card. Map one high-value journey, write 10–15 regression tests, run them daily for a fortnight. You will find at least three things you didn't know about your bot.

If those tests are valuable enough that you want to keep them after the free tier runs out, move to Starter ($49/month). If your team grows past two users or you need more concurrency, Team ($499/month). If you need SSO, API access and >500 concurrent activities, Enterprise ($4,999/month).

Per-second billing means there is no penalty for over-buying capacity. You only pay for the minutes you actually use.

How to compare vendors honestly

When you're comparing voice testing vendors, normalise to per-minute cost.

Take the proposed annual contract from each vendor. Estimate the call minutes you'll actually run in a year — daily regression × 250 working days, plus load testing × planned cadence, plus ad-hoc. Divide. The all-in per-minute number will tell you, in a single figure, what each vendor is charging for the same underlying service.

Don't be surprised when the gap is 5–10x. It usually is. Whether that gap is justified by the rest of what you're getting (services, breadth, certifications) is a real question. Just answer it with numbers.
