Latency is the whole product

A pause that feels fine in a chat feels broken on a phone call. Why response time decides whether an AI voice sounds human.

In text, a two-second wait is nothing. On a phone call, it’s an awkward silence — and awkward silences are when people say “hello? are you there?” and hang up.

Where the time goes

  • Hearing the prospect finish speaking (and not cutting them off).
  • Understanding what they said.
  • Deciding what to say next.
  • Turning that reply into natural-sounding speech.

Each step is fast on its own. Chained together over a phone line, they add up. The work is in overlapping them so the reply starts before the whole pipeline finishes.

“Nobody remembers a clever answer that arrived late.”

Interruptions are a feature

Real people talk over each other. A voice agent has to stop speaking the moment the prospect starts, and pick the thread back up without repeating itself.
