Missed calls, lost revenue
After-hours and peak-time calls go unanswered and customers move on.
Voice AI Agents
Voice AI agents and conversational AI
We build voice agents that answer calls and voice notes, understand intent, look up orders or records, and reply in a natural voice, then hand off to your team when a person is needed. Latency, cost and safety are engineered for real conversations.
What you can expect
- Round-the-clock coverage without adding headcount
- Instant answers to routine calls
- Clean hand-off to people with full context
(01) The problem
Why teams come to us for Voice AI Agents.
Scroll
Phone menus customers hate
Press-one menus frustrate callers and can't handle real questions.
Latency kills conversation
Every hop (transcription, reasoning, speech) adds delay that makes bots feel robotic.
Risky edge cases
Sensitive or emotional conversations need careful guardrails and escalation.

Our approach
How we deliver reliable results.
- 1
Design the conversation
Intents, tone, escalation rules and the things the agent must never do.
- 2
Engineer the latency budget
Streaming, time to first token and caching tuned so replies feel natural.
- 3
Ground every answer
Responses come from your knowledge base and live systems, not improvisation.
- 4
Test what you can't eyeball
Automated suites cover dialogue, sessions, webhooks and security separately from the audio.

Common questions about Voice AI Agents.
Can't find your answer? Ask us on a free strategy call or send a short brief.
How natural do voice agents sound?
Modern speech synthesis is close to human. We tune the voice, pacing and latency so conversations feel natural rather than scripted.
Can a voice agent hand calls to a person?
Yes. Escalation rules route out-of-scope or sensitive calls to your team with a transcript and summary.
Which phone systems do you support?
Twilio telephony, WhatsApp Business, SIP trunks and voice platforms such as Vapi, Retell and LiveKit.
What does a voice agent cost to run?
It depends on call volume and model choice. Prompt caching and the right models keep costs low; on one production product, caching cut input-token costs by about 90%.
Can it speak multiple languages?
Yes. Transcription and synthesis support many languages, and the agent can reply in the caller's language.
How do you keep sensitive conversations safe?
Guardrails, risk detection, strict escalation rules and logging, the same safeguards we built into mental-health and recovery-support products.
