## Roark

Roark is a QA and evaluation platform built specifically for voice AI agents, not another agent builder. It closes the loop between testing and production: simulate an agent against hundreds of callers before launch, score every live call once it is running, and use the findings to ship a proven fix. The team behind it is backed by Y Combinator and reports SOC 2 Type II along with HIPAA BAA support.

Simulation is the pre-launch side. Roark runs your agent against realistic personas built from your own call types, including the angry caller, the rambler and the interrupter, with native accents, code-switching and background noise across 45 languages. Adversarial red-team callers probe for prompt injection and social engineering, while load and health tests confirm the agent survives peak concurrency and stays reachable after launch.

The second half is observability. Every production call is scored as it arrives using Roark's purpose-built audio models rather than a generic LLM grading a transcript, measuring pronunciation, accent clarity, emotion, vocal stress, pace, interruptions and dead air alongside resolution, empathy, hallucination and compliance checks. Issues are filed automatically, dashboards and OTEL traces are available, and changes are diffed so you can see that a fix moved the metric without breaking a caller somewhere else. Roark also publishes Live Bench, a free public leaderboard that scores 300+ speech-to-text, LLM and speech-engine combinations over the real phone network.

**Pricing & Plans:** Usage-based, billed in dollars with no seat licenses. Pay-as-you-go starts free with $50 of credit for work-email signups, then $0.15/min of simulation plus provider costs and $0.04/metric/min. Team is $500/month in included usage at lower rates ($0.10/min simulation, $0.02/metric/min) with 25 concurrent lines and 10 seats. Enterprise starts from $4,000/month committed, adds volume rates and controls such as SSO, data residency, DPA and SLA, and supports invoicing and POs.

- **Pre-launch simulation testing:** Run your agent against hundreds of realistic personas, accents, background noise and edge cases before a customer ever dials in.
- **Red teaming and adversarial callers:** Red-team callers attempt prompt injection, jailbreaks and social engineering to check your agent holds policy under pressure.
- **Post-call analysis at scale:** Every live call is scored as it lands on more than 500 metrics, with issues filed, alerts fired and traces attached.
- **Audio-native scoring models:** Purpose-built audio models measure pronunciation, emotion, vocal stress, pace, interruptions and dead air, not just transcript quality.
- **Regression testing and CI gates:** Rerun the whole suite on every prompt or model change and diff it against your last green baseline to catch regressions before merge.
- **Roark Live Bench leaderboard:** The public Roark Live Bench calls 300+ model combinations over the real phone network and ranks them on end-to-end scores.

**Strengths:** Purpose-built audio models instead of LLM-only transcript grading; Covers the full loop from pre-launch simulation to production monitoring to verified fixes; Transparent dollar-based usage pricing with provider costs passed through at cost; Works with existing stacks such as Vapi, Retell, LiveKit and Pipecat

**Limitations:** Usage-based billing can be harder to forecast at high simulation volume; Priced for teams and companies rather than individual hobbyists; Enterprise controls such as SSO, data residency and SLA sit behind a from-$4,000/mo commitment; Value depends on how much of your work already runs on measurable voice traffic
