LUNA · VOICE AGENT · PERSONAL PROJECT

I designed a voice agent
that calls back
in under 60 seconds.

A personal learning project: an AI voice agent that answers, asks a few simple questions and logs each contact in a CRM. My goal was to learn how to design a natural voice conversation, end to end.

DEMO · SOFIA

Sofia — a test scenario
for a fictional clinic.

In this scenario, a contact fills in a form. Sofia calls back in under 60 seconds, gathers the details and sends them to an Airtable base. I wrote the script, the questions and the n8n workflow.

A second version with a native French voice, on the same n8n → Airtable pipeline — to test how the tone and the script carry over from one language to another.
