## Course Overview
This isn't your typical plug-and-play tutorial where you spin up a demo in five minutes and call it a day.
Instead, we're building a **real estate company**, but with a twist … the employees will be **realtime voice agents**!
By the end of this course, you'll have a system capable of:
* ☎️ Receive inbound calls with Twilio
* 📞 Make outbound calls through Twilio
* 🏠 Search live property data using Superlinked
* ⚡ Run realtime conversations powered by FastRTC
* 🗣️ Transcribe speech instantly with Moonshine + Fast Whisper
* 🎙️ Generate lifelike voices using Kokoro + Orpheus 3B
* 🚀 Deploy open-source models on Runpod for GPU acceleration
Excited? Let's get started!
