I have a 4070 sitting around collecting dust that I got from a trade, I've been thinking about setting it up with whispr and TTS and having a way to talk to my house.
I have a couple of smart home integrations, mostly air conditioning, light switches, security, and doors.
What I would like would be to have a few speakers on the walls that can talk to my server where I can say something like, hey computer, turn on the lights in the dining room and the lights in the dining room would turn on without transmitting that information to Google or Amazon.
