Well Scotty, you’ll still have to use the keyboard, but HTML5 has made it possible (without added speech ware like Dragon Speak) to talk to your Chrome 11 (beta) browser.
On special sites (in the meantime just Google sites) like Google Translate (no more excuses, lecajef) a small microphone will appear in the lower right hand corner of the browser (Chrome 11 only) and you will be able to speak into the computer and it will appear in the translation box.
Google Translate will be adding a button in the next 24 hrs. to allow this. Also, You have ‘drag to’ and ‘drag from’ the browser to the desktop and vice versa, as well as location services and super 3D graphics.
Check out the slide show here: http://slides.html5rocks.com/#landing-slide and use Chrome 11 beta while viewing it to try out the features.
And a la Scotty in Star Trek 4:
It’s far from perfect, but it’s a start, and it’s only in beta. It's got recognition problems at this point, and you should be in a quiet place.
Oh yes, and Scotty.... don't chuck that keyboard just yet.
