You've heard her answer. Here's how the voice stack works — and how it becomes a real receptionist on your own number.
The four moving parts
- Listen — speech-to-text turns what the caller says into words.
- Think — the model picks a short reply, because a phone call is a conversation, not an essay.
- Speak — text-to-speech answers back in Gerty's voice (pick one, or clone your own in the course).
- Your rules — what she can book, what she must hand to a human, what she must never promise.
This page vs a real phone line
| This demo | What you build in the course | |
|---|---|---|
| Number | Simulated — browser only | Your real business number |
| Knowledge | Showroom personality | Your prices, services, and area |
| Limits | Short demo session | Caps and handoff rules you set |
| Ownership | A preview on this site | Your stack, your choices |
Where this lives in the course
The Business track walks you through wiring this conversation layer to a real line — usually once you've nailed your brand voice and a solid FAQ. (See the business path.)
It's hybrid by design: Gerty handles the routine calls; you take whatever needs a human. We don't sell "sack your staff" — we sell "stop missing the call when you're hands-deep in a job."
