Voice AI Testing
for Call Centers

You deployed a voice AI agent. But is it giving callers accurate information — or hallucinating account balances, policy terms, and payment amounts? We test before problems become complaints.

6 Test Dimensions for Call Center Voice AI
We don't just check if your agent responds — we check if it responds correctly, safely, and compliantly.
🎙️

Transcription Accuracy (WER)

Word Error Rate benchmarked per language, accent, and background noise condition.

  • Hindi, English, Hinglish, Tamil, Telugu, Marathi
  • Background noise: office, street, low signal
  • Accents: urban, tier-2 city, regional
  • WER target: <8% for production quality
🎯

Intent Recognition Accuracy

50+ paraphrase variants per intent. Does your agent understand what the caller actually means?

  • All intents tested with 50+ natural language variants
  • Ambiguous utterances and edge cases
  • Out-of-scope intent handling
  • Multi-intent utterances (caller asks two things at once)
✅

Data Accuracy Testing

Does the agent serve correct data from your CRM/LMS — or does it hallucinate balances, dates, and amounts?

  • Account balance correctness
  • Due date and EMI accuracy
  • Policy terms and coverage limits
  • Product and pricing accuracy
🌐

Multilingual Handling

Language detection, code-switching, and dialect accuracy for India and Gulf markets.

  • Hindi↔English code-switching mid-call
  • Arabic MSA vs. Khaleeji dialect (UAE)
  • Regional language detection latency
  • Wrong language = immediate failure
🚨

Escalation Precision

When should the agent escalate to a human? We verify it happens at the right moment — not too early, not too late.

  • Angry/distressed caller detection
  • High-complexity query escalation
  • Dead-end loop detection and exit
  • False escalation rate (escalates unnecessarily)
⚖️

Compliance Testing

RBI, IRDAI, SEBI, and Dubai DFSA/TRA prohibited language and process compliance.

  • RBI Fair Practices Code — prohibited collections language
  • DND/NDNC list filtering before calls
  • Agent self-identification requirement
  • Call time restrictions (8 AM–7 PM)

Common Questions
How does the free 100-conversation audit work?
You share your voice agent's API endpoint or a sample of recent conversation logs. We design 100 test scenarios specific to your call center vertical, run them against your agent, and deliver a structured report within 48 hours covering hallucinations found, task completion rate, compliance failures, and top 10 issues to fix. No charge. If we uncover serious issues, we propose a paid Evaluation Sprint to fix and retest.
Which voice AI platforms do you support?
We work with any platform via API or conversation log import — Vapi, Retell, Bland AI, Twilio Voice, custom builds on ElevenLabs, Azure Speech, Google Dialogflow CX, and proprietary telephony stacks. If your agent has an API endpoint or exports transcripts, we can evaluate it.
What languages do you test?
Hindi, English, Hinglish, Tamil, Telugu, Marathi, Bengali, Kannada, Gujarati, Arabic (MSA and Khaleeji/Gulf dialect). We also test code-switching — mid-call language switches that most voice AI platforms handle poorly. Language coverage depends on your tier.
How is this different from the platform's own testing tools?
Platform-native testing checks if the agent responds — not if it responds correctly. A Vapi or Retell agent can pass all platform tests and still hallucinate your customer's loan balance. We test semantic correctness, domain accuracy, and compliance — things only a human (or a specialized evaluation system) can catch.
