Building HealthVoice, an AI receptionist that knows when to hand over

Every clinic has the same problem. The phone rings while the receptionist is checking someone in, so it goes to voicemail, and a patient who wanted an appointment quietly books somewhere else instead. Missed calls are missed revenue, and no clinic has the staff to catch every one.

HealthVoice is our answer: an AI receptionist built specifically for Cliniko practices. It answers every call, day or night, books, reschedules and cancels appointments straight into the clinic's calendar, recognises returning patients by their number, and handles the routine questions that eat a front desk alive.

The technically interesting parts were real. Twilio carries the calls, ElevenLabs gives it a voice people forget is software, and a two-way Cliniko integration means it works against live availability, not a stale copy. We won an ElevenLabs grant along the way, which helped.

But the part I'm proudest of isn't the AI. It's knowing when to switch it off.

The temptation with a system like this is to make it handle everything, because that demos well. In healthcare that instinct is wrong. If someone is distressed, or describing something that sounds urgent, or simply wants a human, the right move is to stop being clever and pass the call to a person immediately. So we built the escalation path first and the impressive features second. HealthVoice triages, and the moment a call is out of its depth, it hands over cleanly instead of bluffing through it.

That's a product decision as much as a technical one, and it's the kind of call you can only make if you understand both sides. You have to know what the model can actually do, and you have to care about the person on the other end of the line more than you care about the demo. Getting that balance right is the whole job.

The clinics that use it don't talk about the AI. They talk about not missing calls anymore. That's the only review that matters.
