Beyond the Average: How Tail Latency Revealed Our Voice AI Blind Spot

Voice AI systems are uniquely vulnerable to tail latency spikes that average metrics completely mask—leaving teams blind until callers start hanging up.

Vox-Bench addresses this critical observability gap, potentially setting a new standard for performance monitoring across the rapidly growing voice AI industry.
