Your voice agents work in the demo.
They break in production.
SuperBryn is the evaluation and monitoring platform that helps you understand why your voice agents fail—and how to fix them.

Trusted by Leading Teams
Your voice agents pass every test. Then they fail real customers.
Demos work perfectly. Production breaks silently. The gap between testing and reality is where trust dies.
You're flying blind in production.
Demos work. Real calls don't. You can't reproduce the failures.
Monitoring millions of calls means sampling—and missing edge cases.
Dashboards show metrics. They don't explain what went wrong.
Every fix is a guess. You're not learning from production.
Evals, monitoring, and self-learning for voice AI.
Generate test scenarios from your data—before you go live
Evaluate every production call, not just a sample
Monitor and trace failures across STT → LLM → TTS
Self-learning loop that improves agents automatically (coming soon)
Everything you need to trust voice AI at scale.
Pre-deployment evals, production monitoring, and a roadmap to self-learning—built by researchers with 14+ years in speech recognition.
Comprehensive Evals
Generate test scenarios from your company's data sources before going live. Then run evals on production traffic to measure what actually happens with real customers.
Real-Time Monitoring
Monitor every call across STT, LLM, and TTS. Track latency, accuracy, sentiment, and task completion with sub-second alerting.
Root Cause Analysis
Trace failures through the entire voice pipeline. Know whether it was the transcription, the reasoning, or the synthesis that broke.
Enterprise Compliance
Purpose-built for regulated industries. Healthcare, financial services, insurance. Full audit trails and compliance reporting.
Self-Learning Loop
Our Observer Agent will feed insights to an Improver Agent that automatically updates your Main Agent. Continuous improvement without human intervention.
Multi-Model Routing
Intelligently route between STT, LLM, and TTS providers based on context, cost, and performance. One integration, infinite flexibility.
Built by researchers. Not just engineers.
Dr. Neethu Mariam Joy
Co-Founder & CTO
"Voice agents fail in production because they weren't built to learn from real-world conditions. We're changing that."
14+ years of research in speech recognition, noise-robust acoustic modeling, and assistive voice technology. PhD from IIT Madras (2011–2018), followed by postdoctoral research at King's College London. Published extensively in IEEE and INTERSPEECH on speaker normalization, low-resource language modeling, and speech recognition for impaired speakers.

We build understanding.
The first voice AI platform built by speech recognition researchers—for the problems they've spent their careers solving.
Research-First Approach
Our team brings 14+ years of speech AI research. We know why voice agents fail—because we've spent our careers studying it.
Production-First Philosophy
We evaluate on live traffic, not synthetic scenarios. Because a test that doesn't reflect reality is worse than no test at all.
Full-Stack Monitoring
Trace issues across the entire voice pipeline—STT, LLM, TTS. Know exactly where and why your agent broke.
Built for Regulated Industries
Healthcare, financial services, insurance. We understand compliance requirements because our customers depend on them.
The Voice AI Reliability Newsletter
Weekly insights on voice AI production challenges, reliability patterns, and what we're learning building SuperBryn.
Frequently asked
How is this different from existing eval platforms?
Most platforms focus on pre-deployment testing. We focus on production—where the real failures happen. Our research background means we understand why voice AI breaks in ways other tools miss.
Do you support real-time monitoring?
Yes. Sub-second alerting on production calls. You'll know when something breaks before your customers complain about it.
How is your team different from other startups?
Our CTO has a PhD from IIT Madras and postdoctoral research from King's College London—14+ years studying exactly the problems we're solving.
Is SuperBryn compliant for regulated industries?
Yes. We're built specifically for healthcare, financial services, and insurance. Full audit trails and data residency options come standard.
