Edge case testing for voice AI teams. Run realistic tests across accents, noise, and jargon before your customers feel the failures.
Accents & Dialects
ASR fails on regional accents and non-native speakers
Background Noise
Calls from cars, cafes, and crowded places break
Domain Jargon
Industry terms, names, and addresses get mangled
Fast Speech & Interrupts
Real conversations have overlaps and rapid responses
Each failed call = lost booking, lost lead, or customer churn

Test what actually breaks in production
We run a library of realistic edge cases against your full conversation flow, across multiple ASR providers.
How It Works
Three steps to know your true failure rate
Stop guessing where your voice agent breaks. Get a clear picture of edge case failures and their business impact.
Connect your voice flows
Describe your voice agent or connect your existing setup. We support all major voice platforms.
We run edge case tests
Our curated test suite runs across multiple ASR providers, testing accents, noise, jargon, and more.
Get your failure report
See exactly where calls fail, which scenarios break, and what you can fix to improve conversion.
Why this is different
- Tests the full conversation, not just raw ASR
- Vendor-neutral across Deepgram, AssemblyAI, OpenAI, Google
- Curated edge case library that improves over time
- Clear failure reports with actionable fixes
Who This Is For
Built for voice AI teams who ship to real users
If your voice agent handles customer conversations, you need to know where it breaks.
Voice AI startups
Running booking, sales, or support calls and need to reduce failure rates before scaling.
Voice agent platforms
Selling to enterprises who demand reliability metrics and edge case coverage data.
Teams launching new voice products
Want confidence in their voice agent before going live with real customers.
Customer support teams
Using voice AI for tier-1 support and experiencing unexplained drop-offs.
Why this is different from what you have
ASR providers test their models. Internal QA scripts are shallow. We test your actual flows.
