Voice agent latency showdown: Phonic responds in 600ms and stops in 600ms
graceisford · x · 2026-09-16
A voice agent latency comparison is making the rounds: Phonic responds in 600ms and stops speaking within 600ms of an interruption, far ahead of Retell AI (2.38s response, 2.74s to stop) and Sierra (3.42s response, 1.06s to stop). In voice UX, how fast an agent shuts up when interrupted matters as much as response time.
