Speech Recognition

For years, there’s been quite a gulf between the promise of computer speech recognition (as seen on Star Trek) and the reality (as seen just about everywhere else). You say “oxymoron”; it types “ax a moron.” (Which is often just what you feel like doing, frankly.)

Microsoft has had a speech-recognition department for years. But until recently, it never got the funding and corporate backing it needed to do a really bang-up job.

The speech recognition in today’s Windows, however, is another story. It can’t match the accuracy of its chief rival, Dragon NaturallySpeaking, but you might be amazed to discover how elegant its design is now, and how useful it can be to anyone who can’t, or doesn’t like to, type.

In short, Speech Recognition lets you not only control your PC by voice—open programs, click buttons, click Web links, and so on—but also dictate text a heck of a lot faster than you can type.

To make this all work, you need a PC with a microphone. The Windows Speech Recognition program can handle just about any kind of mike, even the one built into your laptop’s case. But a regular old headset mike—“anything that costs over $20 or so,” says Microsoft—will give you the best accuracy.

The easiest way to fire up Speech Recognition for the first time is to open the Start screen. Type speech. In the search results, click Windows Speech Recognition.

The first time you open Speech Recognition, you arrive at a very slick, very impressive full-screen tutorial/introduction, featuring a 20-something model in, judging by the gauzy whiteness, what appears to be heaven.

Click your way through the screens. Along the way, you’re asked to do the following:

Now you’re ready to roll. Operating Windows by voice entails knowing three sets of commands:

The following sections cover these techniques one at a time.

Slip on your headset, open Windows Speech Recognition, and have a gander at these all-important spoken commands:

The beauty of controlling Windows by voice is that you don’t have to remember what to say; you just say whatever you would click with the mouse.

For example, to open the little Calculator program using the mouse, you’d open the Charms bar, click to go to the Start screen, right-click to open the App bar to get to All Programs, and finally click Calculator. To do the same thing using speech recognition, you just say, “Start Calculator.”

Here’s the cheat sheet for manipulating programs. In this list, any word in italics is meant as an example (and other examples that work just as well are in parentheses):

The real Holy Grail for speech recognition, of course, is dictation—you speak, and Windows transcribes your words, typing them into any document. (This feature is especially important on tablet PCs that don’t have keyboards.)

Windows’ dictation accuracy isn’t as good as, say, Dragon NaturallySpeaking’s. But it’s a close second, it’s free, and it’s a lot of fun.

It’s also very easy. You just talk—at regular speed, into any program where you can type. The only real difference is that you have to say the punctuation. You know: “Dear Mom (comma, new line), How are things going (question mark)? Can’t believe I’ll be home for Thanksgiving in only 24 more weeks (exclamation mark)!”

Sooner or later—probably sooner—Speech Recognition is going to misunderstand you and type out the wrong thing. It’s very important that you correct such glitches—for two reasons. First, you don’t want your boss/family/colleagues to think you’re incoherent. Second, each time you make a correction, Windows learns. It won’t make that mistake again. Over time, and over hundreds of corrections, Speech Recognition gets more and more accurate.

Suppose, then, that you said, “I enjoyed the ceremony,” and Speech Recognition typed out, “I enjoyed this era money.” Here’s how you’d proceed:

When you finally exit the Alternates panel, Speech Recognition replaces the corrected text and learns from its mistake.

Here are the other things you can say when you’re dictating text. The first few are extremely important to learn.

There are zillions of secrets, tips, and tricks lurking in speech recognition—but here are a few of the most useful:
