AI Voice Agents

A voice agent is judged in the first three seconds: does it understand, does it answer fast, and does it know its limits. We build voice agents for booking, support, intake and qualification that resolve the routine calls end to end — and transfer the hard ones to your team with a transcript and a summary, so the caller never repeats themselves.

The engineering is the same discipline as our chatbots — grounded answers, deterministic guardrails, latency budgets per turn — with a speech layer on top: streaming speech-to-text and text-to-speech, barge-in handling, and conversation design for audio, where a paragraph that reads fine is three sentences too long. Built on the same conversation core we deliver across chat channels, so voice is a surface, not a second system.

What's included

Named deliverables, not vague verbs

Inbound call handling

Reception, FAQs, booking and intake — resolved end to end or routed with context.

Voice conversation design

Flows written for the ear: short turns, confirmations, interruption handling, graceful recovery.

Human handoff done right

Warm transfer with transcript and summary. The caller never starts over.

Grounded speech answers

The same citation-grounded retrieval behind our chatbots, delivered by voice.

Call analytics

Containment, resolution and escalation metrics from day one, so you can see what the agent actually handles.

Evaluator questions

Asked by every serious buyer

How fast does it respond?

Latency is engineered per turn, not hoped for: streaming synthesis starts speaking before the full answer is generated, and the retrieval fast paths we build for chat apply on voice too. Slow answers are the failure mode we design against first.

What happens when it can't help?

It says so and transfers — with the transcript and a one-line summary attached. An agent that knows its limits is what makes the rest of its answers trustworthy.
