Roark for Home Services — voice agent quality for booking, dispatch & after-hours - Roark

Your booking agent has to get the address right.

Dispatch calls turn on the exact street, the exact window, and a quote the company can actually honor. One misheard address and the truck rolls to the wrong house. Roark scores every call — on the audio.

Here's how a booking call goes wrong.

Each one is a wasted truck roll, a no-show window, or a quote you have to eat at the door — and most are inaudible to a tool that only reads the transcript.

The 'Eighty' vs 'Eighteen' address

Caller: It's 80 Maple, not 18. Agent: Got it — sending the tech to 18 Maple.

The transcript reads clean; the audio is wrong. Only an audio model hears the digit the ASR flattened — and that truck rolls to the wrong house.

The wrong arrival window

Caller: Morning only — I work after noon. Agent: Perfect, you’re booked 2–4pm.

The constraint was stated and ignored. Roark fails any booking where the confirmed window contradicts what the caller asked for.

The price you can’t honor

Caller: So how much for the drain clear? Agent: That’ll be a flat $89, all in.

A number invented on the call that no price book backs. The customer holds you to it at the door — Roark flags any quote the agent can’t source.

Dead air on the emergency call

Caller: My basement is flooding right now. Agent: …

A four-second silence on a 2am burst pipe and the caller hangs up and dials a competitor. Roark scores response time and dead air the transcript never shows.

The pushy add-on tone

Caller: I just need the one repair, thanks. Agent: You really should add the $400 membership today.

The words might pass; the delivery is aggressive. The audio model scores tone and pressure the transcript reads as a polite suggestion.

Roark catches every one of these — and proves the fix.

Each failure above is filed with its evidence, becomes a repeatable simulation until a candidate passes, and is verified on your next thousand live calls.

Catch

The ledger above — every failure filed live, evidence attached.

Simulate

Your fix, replayed against the exact failures above.

Review

Every change explicit and diffed — you apply it.

Verify

You ship — Roark confirms the metric moved on live calls.

Break it in staging, not in production.

Run your agent against hundreds of simulated callers (realistic personas, accents, background noise and edge cases) and get every conversation scored before a customer ever dials in.

Scenarios & personas

Hundreds of simulated callers (the angry one, the rambler, the interrupter) built from your real call types.

Red teaming

Adversarial callers that try to break it (prompt injection, jailbreaks, social engineering) so your agent holds policy under attack.

45 languages & accents

Native accents, code-switching and background noise, in every market your agent answers.

Load & health tests

Peak-volume concurrency and always-on health checks, so the agent that passed in staging survives launch day.

Regression testing

Rerun the whole suite on every change and diff it against your last green baseline, so fixing one caller never breaks another.

Run it in CI

Every prompt or model change runs the suite before it merges: quality gates for conversations, not just code.

500+ metrics. Your models, not just an LLM.

Every production call scored as it lands: issues filed, alerts fired, dashboards and OTEL traces on tap, for voice calls and chat threads alike. And where most tools grade a transcript with an LLM, Roark runs purpose-built audio models on the call itself, measuring what your customer actually heard.
