Test Every Voice Channel. One Platform.
Inbound IVR & Support Bot Testing
Test IVR systems and inbound support bots with real phone calls, and score every call across 30+ metrics, from intent recognition to containment.
Live Call Monitoring
Track real-time call duration, speaker-identified transcripts, and DTMF detection on every test call.
30+ Call Metrics
Measure FCR, intent recognition, CSAT, containment rate, voice quality, and STT accuracy.
Production Recording Analysis
Upload production call recordings for batch analysis with the same evaluation metrics.
From the First Ring to Production
Every Stage of Your Call Agent, Covered
Simulate live inbound and outbound call scenarios before launch, then batch-analyze real production recordings with the same metrics.
Total Quality Coverage for Voice Agents
Measure what matters across every conversation, from intent recognition and STT accuracy to bias and hallucination, so every call meets your standard.
UX and Business Ops Metrics
Track the metrics that matter most to your contact center, from CSAT and sentiment to containment rate and handoff trends.
Confidence by Evaluation
Quality scores are weighted by evaluation volume, giving you a reliable signal on whether your IVR or voice agent is ready to ship.
Inside IVR Testing on TestMu AI
DTMF & MENU TESTING
Validate DTMF Menus and Call Routing
Confirm every keypad press lands where it should. TestMu AI navigates your menu tree, detects DTMF tones, and verifies routing and transfers on every call.
Try for free
- Menu-tree navigation across every branch and timeout
- DTMF tone detection on inbound and outbound calls
- Call routing, transfers, and fallback verification
AI VOICE AGENT TESTING
Test AI Voice Agents Like Real Callers
AI voice agents do not follow a fixed script. Our evaluator calls your agent like a real customer and scores intent recognition, speech-to-text accuracy, and compliance.
Try for free- Intent recognition accuracy across personas and accents
- Hallucination, bias, and guardrail checks on every turn
- Speech-to-text and voice-quality scoring
LOAD & PERFORMANCE
Scale to Concurrent Calls and Wire It Into CI
Customer traffic spikes and your IVR has to hold. Simulate concurrent calls, schedule cron-driven runs, and wire regression suites into CI, all on HyperExecute.
Try for free- Concurrent call simulation to stress routing and capacity
- Scheduled and cron-driven regression runs
- CI/CD integration for every release
PRODUCTION ANALYSIS
Catch Regressions Before Your Customers Do
Test calls catch what you script; real calls catch what you do not. Upload production recordings and batch-analyze them so a drop in containment or CSAT never slips by.
Start Testing Your IVR- 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 IVR Testing
Project & Environment Management
Create agents, manage test environments, and scope variables with bulk creation support.
