Cutting First-Token Latency in Production Voice AI
A walkthrough of the latency budget across STT, routing, model, and TTS, with measurements from a quarter of live calls and the three changes that moved the needle from 1.1s to 612ms.
Read article→Matthew co-founded Devpro and leads strategy and delivery across enterprise AI communication deployments. He focuses on production voice systems, client partnerships, and the operational discipline needed to ship AI into high-stakes environments. Before Devpro, he worked at the intersection of software delivery and customer operations, which shaped how the company scopes discovery, rollout, and managed services. He spends most of his time with operators: mapping call flows, clarifying SLAs, and making sure every deployment has a clear path from pilot to steady-state production on Vatel.
