Our voice AI development work is judged on how it handles the call nobody scripted for — the caller who goes off-topic, interrupts, or asks something out of scope. That's where most voice agents fail, and where we spend most of our engineering effort.

Voice AI is a conversational agent that handles real customer calls — understanding intent from speech, managing multi-turn dialogue, and taking action or routing the caller, all in real time over live telephony. It's a different engineering problem from a chat agent: there's no typing delay to hide behind, no edit button, and a caller who hangs up if the agent stalls for two seconds.
The gap between a voice AI demo and a voice AI system you can put in front of customers is almost entirely about what happens when the conversation goes somewhere the demo script never covered.
Every voice agent we ship is built around the same three pieces, in this order.
Connected to your existing phone system and CRM, with speech-to-text and text-to-speech tuned for low latency — not a cloud round-trip the caller can hear.
Trained on the actual phrasing your callers use, not a generic intent model — so the agent recognizes what's being asked even when it's not asked the way you expected.
When a question falls outside what the agent can handle, it hands off to a human with full conversation context — rather than guessing or looping the caller. See our Trust & Safety framework.
The questions we get asked most about voice AI development — answered straight, no sales pitch.
It depends on call volume, how many intents the agent needs to handle, and whether it integrates with an existing phone system or CRM. We price by milestone, not by the hour, so the number is fixed before work starts. Book a call and we'll scope it in detail.
Most voice agents are built and tested against the happy path — the questions the team expected. In production, callers ask things nobody scripted for, and a system with no escalation path either guesses or loops. We build every voice agent with an explicit out-of-scope detector and a defined handoff to a human, so the failure mode is a clean transfer, not a confused caller stuck in a loop.
Yes — we connect to your existing telephony provider and CRM rather than asking you to migrate to a new platform. See our LLM integration work for how we connect AI systems into infrastructure you already run.
The agent passes full conversation context to the human — not just a transferred call with no history. The caller doesn't have to repeat themselves, and the human agent sees exactly what was asked and what the AI already tried.
Book a 30-minute call — we'll tell you honestly whether voice AI is the right fit for your call volume, and what it would take to ship it.
