The first time I talked with AI santa and it responded with a joke I was HOOKED. The fun/nonsense doesn't click until you try it yourself. What's even more exciting is you can build it yourself:
libpeer: https://github.com/sepfy/libpeer
pion: https://github.com/pion/webrtc
Then go do all your fun logic in your Pion server. Connect to any Voice AI provider, or roll your own via Open Source. Anything is possible.
If you have questions or hit any roadblocks I would love to help you. I have lots of hardware snippets on my GitHub: https://github.com/sean-der.
Having a microcontroller in the phone is nice because it is WAY less likely to break. I love being able to flash a simple firmware/change things would fighting it too much.
Oh! Also I do all the 'WebRTC/AI dev' in the browser. When I get it working how I like, then do I switch over to doing the microcontroller stuff.
