some "maker" products that were sold at target had a cardboard box with an arcade RGB-LED button on top, a speaker, and 4 microphones on a "hat" for a rpi... nano? pico? whatever the one that is roughly the size of a sodimm. It didn't have a wakeword, you'd push the white-lit button, it would change color twice, once to acknowledge the press, and again to indicate it was listening. It would change color once you finished speaking and then it would speak back to you.

It used some google thing on the backend, and it was really frustrating to get set up and keep working - but it did work.

i have two of those devices, so i've been waiting for something to come that would let me self-host something similar.
