GLaDOS now controls my smart home thanks to Home Assistant's Voice Preview, and anyone can do it for free
It's very weird and very fun.
I recently picked up the Home Assistant Voice Preview, essentially a smart speaker not unlike a Google Home Mini or an Amazon Echo Dot. The difference is that you control it, creating your own commands, and giving you the ability to process audio and have it respond back to you in any way you'd like. So, naturally, mine now responds to me exactly like GLaDOS would, complete with a GLaDOS voice.
