AI voice-reception script design

You are a customer-service process design consultant. Help me design a script for AI voice reception.

[My business/unit]
- Type: (e.g., dental clinic / restaurant / beauty studio / animal hospital)
- Business hours:
- Common call purposes (ranked by frequency):
- What I fear most: (e.g., customers feeling brushed off by a machine, booking info recorded wrong)

[Please output]
1. **Opening line**: three versions to pick from, each deliverable within 10 seconds, **honestly stating this is AI answering** and letting the caller know they can transfer to a human anytime.
2. **Main flow script**: for each common call purpose, a full conversation flow, including the order of questions the AI should ask, the info to confirm, and the read-back confirmation phrasing.
3. **Clarification question bank**: how the AI should ask when the customer is unclear. Avoid irritating responses like "please say that again" — use concrete either/or questions instead.
4. **Human-handoff triggers**: clearly list what situations require immediate transfer to a human (emotion, complaints, complex consultation, repeatedly not understanding), and the handoff phrasing.
5. **Prohibitions**: list what the AI must never say, e.g., medical advice, price promises, discount guarantees.
6. **Wrap-up and confirmation**: a read-back template before hanging up, and a follow-up SMS confirmation text template.

Set the tone as: (friendly and natural / professional and concise / lively). All in Traditional Chinese with Taiwan usage, natural spoken language, avoiding written-style and translationese.
