I can’t believe that “My Summer Car” isn’t on here, I feel like it fits the theme of amazing but slightly disturbing Finnish games

I might be misunderstanding the question, so if you’re looking to make an existing android device you have work like this, please ignore the below.

Maybe a Google Nest Mini would do what you’re looking for? It’s definitely got the ability to be interacted with entirely verbally, but I guess the downside is a smaller selection of apps that do work with it (there is a list on the Google store of which apps it works with)

The car and road are from the cover of a Nickleback album: https://en.m.wikipedia.org/wiki/All_the_Right_Reasons
