End-to-End Voicebot Testing
AI-native evaluators that generate voice scenarios, simulate real callers, and score voicebot quality across 9 metrics.
Voicebot Response Evaluation
Score every voice conversation across 9 quality metrics via generated WAV audio: hallucination, bias, context retention, completeness, and conversation flow.
9 Voice Quality Metrics
Score bias, hallucination, completeness, context awareness, response quality, conversation flow, tone consistency, and more on every spoken turn.
WAV Audio Evaluation
Voice agents are tested via generated WAV audio interactions, the same evaluation workflow as text-based agents, delivered via spoken conversation.
Go-Live Verdict
Every voicebot evaluation closes with a Green, Yellow, or Red production-readiness assessment across 4 weighted quality dimensions.
Complete Voicebot Testing Coverage
Evaluation Confidence by Test Volume
Every voicebot quality score is weighted against the evaluation volume that drove it, so low-volume scores are flagged as less reliable.
9 Voicebot Quality Metrics Per Conversation
Hallucination, bias, completeness, context awareness, response quality, conversation flow, tone consistency, root-cause understanding, and positive user outcome, scored per voice interaction.
4-Dimension Go-Live Assessment
Every run scores Functional Completeness, Quality Standards, Risk Profile, and Operational Readiness, each weighted at 25%, into a single production-readiness verdict.
Pass/Fail Analysis for Every Voice Scenario
Pinpoint every match and discrepancy in voicebot responses, tracked as Pass, Fail, or Partial against your defined criteria and voice quality thresholds.
Built for Every Layer of Voicebot QA
Project and Environment Management
Create voicebot test projects, manage environments, and configure variables with bulk scenario setup for multi-region voice deployments.
Persona Library and Voice Profiles
Test across 10 pre-built caller personas and 200+ voice profiles - from impatient callers to international speakers with diverse accents.
Custom Validation Rules
Define evidence-based pass/fail criteria per voice scenario - from required disclosures to escalation triggers - with High, Medium, and Low confidence tracking.
Secure Infrastructure
Run voicebot evaluations via HyperExecute with optional secure tunnels for agents behind corporate firewalls or in private VPC environments.
Scheduled Regression Testing
Automate voicebot regression runs on preset frequencies or custom cron schedules with IANA timezone support to catch quality drift early.
Observability and Reporting
Monitor voicebot quality across test runs with unified dashboards, exportable audit reports, and real-time metric trend analysis.
