In reading the comments here I see that some people do use voice with their hand rectangles for other purposes than speaking to someone. I never do even though there is some Google Assistant icon staring at me. If I accidentally start recording my voice by fumbling buttons then I instinctively try to stop it so I can continue pecking into the keyboard. Is it a generational thing and will future generations find typing into a search box as anachronistic as I find using a land line with a rotary dial? I am also British and therefore not as loud as some people in the English speaking world. Talking to my phone on the train would make me cringe. Clearly people like me will die off soon enough, however, is adoption a problem for these voice technology things? How do people get into changing habits from pecking at a keyboard to the evidently easier voice driven way of doing things? Is there one use case, e.g. in the car, where the habit of speaking to a gadget is learned?
