But how? Even if those interfaces were actually working, it's still extremely inconvenient to talk when you can click. You have to be somewhere where talking out loud doesn't disturb the people around you. That excludes most situations: open space offices, restaurants, coffee shops, public transport, cars with passengers, and most places in the home except maybe the bathroom.
And even if you're all alone in a silent place, giving instructions out loud takes more time than configuring a screen, and will always be error prone, because the feedback will always be ambiguous and imprecise.
Except maybe if the feedback is on a screen, but then if there's already a screen, why not use it.
