Voice AI for appointment booking: Build a Vapi + ElevenLabs Agent that books slots and sends reminders 24/7

说明与用途

使用 Vapi、ElevenLabs、n8n、Google Calendar 和 Twilio 的自动化语音预约系统，创建事件、发送短信确认并通过语音提醒客户。

问题

Automate phone-based appointment booking, confirmation, and reminders without manual intervention.

结果

A 6‑8 hour build that delivers a 24/7 voice‑first appointment system with automated confirmations and reminders, reducing manual workload and improving client experience.

工作流

• Create Vapi voice agent with intents and webhook URL
• Provision ElevenLabs TTS voice and API key
• Enable Google Calendar API and obtain OAuth credentials
• Set up n8n Docker container and configure credentials for Vapi, ElevenLabs, Google Calendar, Twilio, (optional) OpenAI
• Build n8n workflow: webhook node → function node to normalize date/time → Google Calendar event creation → Twilio SMS confirmation → scheduled reminder branch that calls back using ElevenLabs TTS

证据

You can wire Vapi's speech-to-intent engine to ElevenLabs' neural text-to-speech, then glue the two together with an n8n workflow that talks to Google Calendar and Twilio.
