VoiceProbe
Automated QA testing and monitoring for voice AI agents
● The Problem
Voice AI agents handle millions of calls but break in subtle ways: latency spikes, gibberish responses, interruption handling failures, and personality drift. Manual QA catches less than 5% of issues. Cekura (YC W24) proved the market with 75+ customers, but the space is early and underserved.
● The Solution
Connect your voice agent (Retell, Vapi, Bland, or custom). VoiceProbe runs simulated conversations with persona variations, interruptions, and edge cases. Monitors production calls for latency, sentiment drift, gibberish, and resolution rates. Alerts and CI/CD integration.

Usage-BasedCompetitive Landscape
Cekura (YC) is the category leader with 75+ customers and $2.4M funding. Hamming.ai focuses on telephony testing. Arize and Langfuse cover general LLM observability but miss voice-specific signals like latency, interruptions, and pitch analysis.
Why Now?
Voice AI deployments crossed the production threshold in 2026. ElevenLabs at $330M ARR, Deepgram at $1.3B valuation. Every production voice agent needs QA, but most ship without it. Regulatory pressure in healthcare and finance demands audit trails for AI calls.
