AI Voice Agent
An AI voice agent answers phone calls, understands what the caller wants and takes action — booking an appointment, answering a question, routing to a person. It combines speech recognition, a language model and speech synthesis over a phone line.
The technical constraint that shapes everything is latency. A pause longer than roughly a second reads as a dropped call, so the pipeline — transcribe, decide, speak — has a very small budget. This is why voice agents use faster, smaller models and pre-generate common responses.
Handling interruption well matters more than voice quality. Real callers talk over the agent, change their minds mid-sentence and give a phone number in three chunks. An agent that can't be interrupted feels broken regardless of how natural it sounds.
Why it matters
The measurable case is missed calls. For a business where an unanswered call is a lost job, an agent that answers every call after hours has an obvious payback — and unlike a receptionist, it doesn't have a busy hour.
