GTM Engineering · SpeechifyAI
Vrishab Nair is a GTM engineer at SpeechifyAI, working on the go-to-market side of the developer platform: the tooling that connects the API to the people building on it. He writes about voice AI the way a buyer evaluates it: cost per minute, time to first byte, and whether the published numbers survive contact with a real workload.
A voice agent's tool call happens inside a turn the caller is waiting through, which makes it a latency decision before it is an architecture one. The rule: reads that return fast run inline, writes and slow lookups get a receipt and finish asynchronously.

The three ways an ecommerce brand answers the phone, normalized to cost per talk minute so they are comparable. Outsourced call centers run $0.35 to $1.35 a minute and voice agents run under $0.08 all-in, but containment rate decides more than either number.
