how does wake word work? Does it keep listening and ignore if the last few seconds does not have the wake word/phrase?
that's the general idea, yes. Or rather, store several chunks of audio, and discard the oldest. aka "Rolling window".

#22Funny, I just picked up a device for use with https://heywillow.io for similar reasons
me too, but I bricked mine when flashing the bios. just a fluke, nothing to be done about it.

#23Is it possible to run this on a generic linux box? Or if not, are you aware of a similar project that can?
I've googled it before, but the space is crowded and the caveats are subtle.

#24I wanted to create a voice assistant that is completely offline and doesn't require any internet connection. This is because I wanted to ensure that the user's privacy is protected and that the user's data is not being sent to any third party servers. Props, and thank you for this.
I would love for Apple/Google to introduce some tech that would make it provable/verifiable that the camera/mic on the device can only be captured when the indicator is on and that it isn't possible for apps or even higher layers of OS to spoof this

#25All I need is a voice assistant that: - RPi 4 can handle, - I can integrate with HomeAssistant, - is offline only, and doesn't send my data anywhere. This project seems to be ticking most, if not all of the boxes, compared to anything else I've seen. Good job! While at it, can someone drop a recommendation for a Rpi-compatible mic for Alexa-like usecase?
Check out Rhasspy.
You won't get anything practically useful running LLMs on the 4B but you also don't strictly need LLM-based models.
In the Rhasspy community, a common pattern is to do (cheap and lightweight) wake-word detection locally on mic-attached satellites (here 4B should be sufficient) and then stream the actual recording (more computational resources for better results) over the local network to a central hub.

That’s allegedly the case in iOS (not the provable part, but I wonder if anyone managed to disprove it yet?)

I'm thinking perhaps a standardized open design circuit that can you can view by opening up back cover and zooming in with a microscope.
feel like privacy tech like this that seemed wildly overkill for everyday users becomes necessary as the value of collecting data and profiling humans goes through the roof

I missed the reference. Red nail polish?

I have got good results with Playstation 3 and Playstation 4 cameras (which also have a mic). They are available for $15-20 on ebay.
