Re: Non-Connected solutions
Over 20 years old, but not getting any love.
However companies see it as more advantageous to use their own server than embed it.
I've used perfectly good embedded voice control of PC, car radio, phone on things 10 to 20 years old. Corporate bosses are not interested in improving the local SW, or providing it at all. Hence your <whatever> controlled by an App, which can can be voice controlled is via TWO servers on the Internet, Google/Apple/MS/Amazon Voice to Text (and Machine Learning is just a (partially) human curated dataflow database, not real AI), then the App uses the IoT maker's Server.
So no privacy and it's subject to hijacking, exploitation and failure due to Internet connection and/or server failure. It will end badly see "No Silver Lining" "Ray McCarthy".
