This is a brilliant idea. I'm curious about a lot of the implementation specifics like how audible the white noise is in a silent room and what kind of UX trade offs it brings.

Yeah, I'm wondering how it should work when you say the wake word too. Like if I say "Sister Assumpta, what's the weather like?" is it just going to repeat the same command but replace "Sister Assumpta" with "Hey Google?" Thus slowing the whole thing down?

I'm curious whether it will handle the audio trigger as well as Google/Amazon/Apple. It takes some pretty advanced audio algorithms to catch "hey Google" in a busy kitchen. It would be pretty frustrating if this device caused these devices to trigger even more inconsistently.

I love this idea. I've wanted to do something similar for a long time, but I was thinking about building a home assistant where the always-on mic was a complete separate board that only listened for wake words and had no internet access. The main mic would only be powered on when the smaller board woke it up. Alias achieves the same thing in a much simpler way to where I might actually consider buying a home assistant now.

Seems to me based on the description that it only says "Hey Google" to the device and then lets your voice through by cutting off the white noise. That would mean the only delay would be between when you say the wake word and when Google starts listening.

Ya, my echo devices can hear me across the kitchen, with people talking near it, while the water is running, and the TV is on (in the distance). That's a core feature for me. If this device dropped that capability, I'd rip it off in a day.
