✓ Greeting flow — 1.2s response, intent: confirmed
✓ Booking — party_size=4, date=tomorrow, slot: filled
✓ Interruption handling — graceful recovery in 0.8s
✗ Ambiguous input — agent stalled for 4.2s (timeout)
✓ Escalation — transferred to human in 2.1s
✓ Cancellation — confirmed with empathy response

Capabilities

Everything you need to test voice agents

From scenario design to production monitoring — a complete quality assurance toolkit.

Synthetic Voice Calls

Simulate realistic phone conversations with AI-generated voices. Full end-to-end call testing.

Test Suites & Scenarios

YAML-based scenarios with branching logic. Group into suites and run hundreds of variations.

Latency & Performance

Track response times, turn-taking delays, and p95 latency. Catch regressions across builds.

Intent Accuracy Scoring

Evaluate intent recognition, entity extraction, and conversation flow adherence automatically.

CI/CD Integration

Run test suites on every deploy. Block releases when voice agent quality drops below threshold.

Transcript Analysis

Turn-by-turn scoring with full transcripts. Export CSV or PDF for compliance audits.

Workflow

Three steps to confident deploys

01

Define Scenarios

Write YAML test scenarios with caller dialogue, expected intents, and evaluation rubrics.

scenario: booking-flow
steps:
  - caller: "Book a table for 4"
    expect_intent: reservation
  - caller: "Tomorrow at 7 PM"
    expect_action: confirm
02

Run Simulated Calls

Execute suites with synthetic voices. Parallel workers process hundreds of calls in minutes.
