There's lots of reason it hasn't taken off like some hoped (accuracy, social aspects, privacy) but it's not faster unless you have no other option for input. If I have a computer, typing is faster, if I have a phone, which we almost always do, it's faster to trigger the command or type. Speech is competing against every other tech item trying to be convenient, from laptops to phones to watches... the only space where I'd want it is something like baking or cooking when I can't interface with a computer. (edit) and what about the response back? A visual interface I can confirm at a glance whether my input was accurate, a voice one I have to listen to the whole thing. I even don't like maps directions in the car as half the time I know the next direction already and don't want the interruption to music or whatever I'm listening to.
