Excerpt from a Walt Mossberg iOS and Android voice dictation review

"While the microphone keys work a bit differently on the two platforms, they are basically similar. When the keyboard appears, ready for you to type, you can instead hit the microphone key and simply dictate what you want to say. The phones then send your spoken words to a remote server, which rapidly translates them into text and sends them back to the phone’s screen. If corrections are needed, you make them by typing, though both platforms make this easier by indicating the likeliest errors, and suggesting alternatives."
