I refuse to put an amazon/apple/google surveillance device in my home, so I am very interested in a DIY digital assistant device. I'm aware of a few options but it seems like offline voice recognition is always a little sub-par. I am really looking forward to the day when an offline, open source digital assistant can compare in quality to a proprietary/cloud device.
uh, "cloud" isn't a magical thing that has specialized hardware for voice recognition. It is just a computer. Just like the device you have locally.
So if the device locally can run the NN then there is no need to have a "cloud" do it. You only add latency.
