Picture this...you're setting in front of your computer, staring at the desktop trying to decide if you want to surf the Net or do a little word processing. You finally decide to write to your in-laws and see if they got the pictures you sent them.
Instead of reaching over and moving the mouse pointer to the "Word" icon, you simply speak, (Assuming you've already put on your microphone headset) "[computer load Microsoft Word.]" And while you watch, the desktop disappears and Microsoft Word appears. So far so good. Next you say, "[new file]" and immediately, a new white screen appears in front of you. (This could be habit forming) Now, it's time to write, but you never touch your keyboard.

Again, you speak to your computer, "[new paragraph] Hi Aunt Ruth [comma new paragraph] I was just thinking about you and wondered what you thought of the kid's pictures I sent you last week [question mark new paragraph]."

I'm able to operate in this "No hands" mode because of a voice recognition program called Naturallyspeaking. Not only can it transcribe your speech, as you speak, it can also be used instead of the keyboard and mouse to control your computer. This is only one of several such programs on the market. I chose Naturallyspeaking because of its excellent reviews. How well does it work? Most of the reviews say that with sufficient training the computer will achieve an accuracy of over 95%. I've not reached anywhere near that yet, but my computer is still in its infancy. Fortunately, it's a quick learner!
Before I could actually start controlling my computer by voice, I had to train the program to recognize me, and the pattern of my speech. Each person will be different. Humans have little trouble in deciphering what another person is saying, even if they stumble over a few words or leave one out entirely. We group words into sentences and our brains tend to fill in any missing parts. But computers don't have this luxury. So it's very important that they know our voices, the way we enunciate, and most of all, the patterns in which we string words together.
Training is easy though somewhat boring. In order to understand your voice, the computer has you to read something it has already analyzed. Dragon software uses the text from several popular novels in these reading/learning exercises. As you read the text, the computer compares the way you pronounce certain words with patterns previously stored in its memory. As you read into the microphone, the computer builds a voice file that describes in phonetics, exactly how "you" speak. After a while, the computer will have discovered patterns in your speech and will be able to extrapolate these patterns to new words that it has never heard you speak before.
Working with "voice recognition" takes a little extra thought. Because the computer doesn't know when you've reached the end of a sentence or a paragraph, you have to tell it. There are dozens of commands you can use already programmed into the software. Words like, "new paragraph, space, new line, backspace, erase word, correct that, etc." These words tell the computer that you want it to perform a command of some kind.
In the actual document, these commands never appear on the screen. I enclosed the commands in brackets above so you could see how, when, and where I was using them.
The first time I spoke into my microphone and watched the words magically appear on the screen gave me an eerie feeling. It was like some unknown hand was typing my thoughts.
Naturallyspeaking comes with a microphone included in the package. All of these types of programs are very particular about the quality of the microphone being used. The voice engine requires high quality sound files so the microphone plays a crucial role in determining the final accuracy that can be achieved. It's also very important to speak into the microphone exactly the same way every time. Otherwise, you'll have to reset the sound levels every time you want to use voice control.
Dragon Software is not the only producer of "voice recognition" software. IBM has its own product as well as several others. If you think you might be interested in finding out more about voice recognition, check out these links.

One thing I haven't yet mentioned is that you can turn the tables and have the computer read printed text back to you. I'm using it to proof my new book by having the computer read aloud my text files. Welcome to the 21st century!
