Windows XP and Speech Recognition

I used to watch Star Trek in envy as the ship’s computer “listened” to
the crews’ instructions and responded with perfect understanding.
Speech recognition is not there yet, but why let lack of perfection
stop us from trying?
Speech recognition has come a long way since it was first introduced
to personal computers. On a basic level speech recognition is the
process of converting an acoustic signal, captured by a microphone,
and transforming it into words on a document.. The procedure is highly
technical, but you don’t have to understand its inner mysteries to use
it any more than you need to know how an automobile is designed in
order to drive it.
Many
of those who have Windows XP installed believe that speech recognition
is built into XP. That’s because many PC vendors install Microsoft’s
speech recognition software along with XP as a convenience to
customers. Click on the Start button and go into Control Panel. Locate
the Speech icon and open it with your mouse. A dialog box will appear.
If it has a Speech Recognition tab, the program is already installed.
If speech recognition is not installed you have several options. You
can buy Microsoft Plus! for Windows XP for about $30. This is the
least expensive option. You get some additional goodies with the
package for your money, but they’re not important to our discussion.
If you have Microsoft Word or Office installed, and you don’t have the
Speech Recognition tab in the above mentioned dialog box, the program
was not installed by default. Fortunately, it’s easy to install from
Word. From the Tools menu open the Speech option. Choose Yes when
you’re asked if you want to install the program. You will probably
need the installation disk.
You didn’t think you were finished, did you? The program needs to be
trained like a puppy dog. It won’t mess your carpet, and you don’t
need to take it for a walk, but you do have to show it how
to speak appropriately.. The program will assist you with the proper
position of your microphone, and it will help you create a profile.
The profile stores your unique speech patterns and any pronunciation
quirks you may have. You can use one of three different voices as your
default, Michelle, Michael, or Microsoft Sam. They could all stand
some improvement, but I prefer Sam.
All that’s left is for you to “train” the program to convert your
speech into words on the document. Start the training from the Speech
option in the Tools menu. You will be offered a selection of different
texts to read, ranging from Bill Gates’ book “The Road Ahead” to Edgar
Allen Poe’s “Fall of the House of Usher”. The more text you read, the
more accurately the program will convert your speech to text. In time,
you can experience an accuracy rate better than 98%.
Get a high quality microphone. A noise-canceling headset can be
purchased for less than $50. Speak naturally, the same way you would
speak to another person in a normal conversation. Don’t try training
the program as if it were a child or an obstinate pet. That produces
very poor results and needless frustration.
Even with all the progress in the last decade, speech recognition is
still far from perfect. So why bother using it? It’s an excellent tool
for creating the first draft of a manuscript of any length...
Dictation is a lot easier than using the keyboard and mouse to make
text entries. If you take the time to learn how to correct errors
through the program’s editing utility, you will save time, especially
if you fall into the camp of lousy typists as most of us do.
Speech control allows many people access to computers who could
otherwise not use them through the conventional keyboard and mouse
interface. Those who suffer from visual impairments, repetitive strain
injuries or other physical limitations have found new opportunities
through speech recognition. You may be amazed at what you can
accomplish when you unleash the power of your voice.
There is no reason why speech recognition has to be confined to
computers. This technology is slowly finding its way into homes,
automobiles, factories, and wherever the marketplace dictates.
Speech recognition, like video editing, requires a lot of computer
power. Have at least one gigabyte of memory and a 2.0 MHz processor as
a bare minimum.
