# 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. Backed by YC Live · scoring every call 1,284 today ## 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. ### Audio-native custom models - Address capture - Accent clarity - Pronunciation - Dead air - Vocal stress - Interruptions ### Booking accuracy task - Window accuracy - Quote integrity - Service-type match - Slot confirmation ### Conversational LLM + rules - Tone - Task success - Hallucination - Repetition - Upsell pressure - Empathy ### Performance latency - Response time - Time-to-first-word - ASR WER - Barge-in handling ## First call scored in under a minute.
