Test Every Layer of Your PolyAI Agent. One Platform.
AI-native agents place real calls to score your PolyAI voice assistant across conversation flows, speech, and integrations on 30+ metrics.
Cover Every PolyAI Conversation Flow
PolyAI conversation flows in Agent Studio let callers interrupt, ask clarifying questions, and change topic mid-call. Simulate thousands of callers and score every branch across 9 quality metrics.
Full Path Coverage
Auto-generate 60 to 100+ scenarios from your flow docs, PRDs, or connected Jira and Confluence, then drive callers down every branch and pivot.
Interruption Handling
Prove your agent absorbs barge-in, follows topic shifts, and never restarts the conversation when a caller changes direction.
9 Quality Metrics
Score hallucination, bias, completeness, context awareness, and conversation flow on every turn, even fully off-script.
From Agent Studio to the Live Line
Every PolyAI Conversation Path, Covered
Simulate live callers before launch, then batch-analyze real production calls with the same metrics across every flow branch.
Quality Scoring on Every Turn
Measure what matters across each turn, from intent recognition and speech-to-text accuracy to bias and hallucination.
Containment and CX Metrics
Track the numbers that decide contact-center ROI, from CSAT and sentiment to containment rate and escalation trends.
Confidence by Evaluation
Quality scores are weighted by evaluation volume, giving you a reliable signal on whether your PolyAI agent is ready to answer a live line.
Inside PolyAI Testing On TestMu AI
Flow-path coverage and DTMF, understanding across accents, load and CI, plus production call analysis, all scored on real phone calls.
CONVERSATION FLOWS
Cover Every Path in Your PolyAI Flow
PolyAI callers interrupt and change topic mid-call. TestMu AI drives them down every branch and verifies the agent recovers without restarting.
Try for free- Every branch, pivot, and clarifying-question path
- Barge-in and interruption handling on every turn
- DTMF detection and menu navigation where used
SPEECH & ACCENTS
Prove Understanding Across Every Accent
We call your PolyAI agent with 50+ accents, 200+ voice profiles, and 15 noise presets, then score intent recognition and speech-to-text accuracy.
Try for free- Intent recognition across 50+ accents and 10 personas
- Speech-to-text accuracy and latency scoring
- Hallucination, bias, and guardrail checks on every turn
LOAD & PERFORMANCE
Hold Containment Under Peak Call Volume
Traffic spikes are when containment slips. Simulate concurrent calls, schedule cron runs, and wire regression suites into CI on HyperExecute.
Try for free- Concurrent call simulation to stress the agent
- Scheduled and cron-driven regression runs
- CI/CD integration for every release
PRODUCTION ANALYSIS
Catch Containment Drops in Production
Upload production call recordings and batch-analyze them so a drop in containment, CSAT, or intent accuracy never slips by.
Start Testing PolyAI- Batch-analyze real production call recordings
- Track quality trends across releases over time
- Flag drops in containment, CSAT, or intent accuracy
Built for Every Layer of PolyAI Testing
Project & Environment Management
Create agents, manage test environments, and scope variables across your PolyAI staging and production lines.
Test Profiles & Personas
Drive calls with reusable test data and 10 personas, from International Caller to Accessibility Needs, so you cover every real caller and accent.
Validation Criteria
Define custom, evidence-based pass/fail rules per scenario with High, Medium, and Low confidence tracking on every score.
Security & Infrastructure
Execute via HyperExecute with optional secure tunnels for PolyAI agents behind a private contact-center network.
Scheduling Engine
