All voice recognition software is still useless and gimmicky. Windows built-in voice recognition, all 3rd party software (like Dragon), Android, Windows Phone, iPhone ... all useless. All slower than actually typing yourself because anywhere from 10 - 60% of the time it will get it wrong, so you have to go back and correct mistakes.
Dragon is probably the best, atleast a 90% success rate. But still not great. I'd only ever use it if you do a LOT of typing, like writing a book or long essay, and you've injured your hands so cant use a keyboard. Because it's even more useless when trying to use it to navigate in any form.
