How to turn off Voice Over in Mac?

I find it nuisance for the application that's called VOICE OVER in Mac. Accidentally I turned it on while playing with the machine, and I find it hard to turn off! It's too noisy for me and it's becoming redundant coz I can read what I'm pointing at and know what it means, and I don't need some kind of a translator and remind me what the icon of the window or whatever it is. Finally by pressing

cmd + F5 or

fn + cmd + F5

you can turn it off. Very simple dude yet I'm freaking out when I didn't know how to turn it off, hahaha!
