If it is the surrounding of the house, why not - as long as it is all stored and operated locally with no cloud connection and stuff. Inside the house / apartment /whatever: hell no, even if sb I know would have a cloud voice assitant like alexa, google, siri, etc. I would never enter or at least not stay there. If the voice assistant is something like the one HAS got, that would not be a problem. Also if it is covering the surroundings at no time it should point to public ground like streets, walkways, etc.. That is thing how you get me angry or at least annoyed (and in Germany it can even be illegal lol)
