Speech Recognition in Windows XP
This feature will
describe to you how to use speech recognition in
Windows XP. If you installed
speech recognition with
Microsoft Office XP or if you purchased a new computer
that has Office XP installed, you can use speech recognition in all Office
operating system to convert spoken words to written text. An
driver, called a speech recognition engine, recognizes words and
converts them to text. The speech recognition engine may be installed with the
operating system or at a later time with other software. During the
installation process, speech-enabled packages, such as word processors and Web
browsers, may install their own engines or they may use existing engines.
Additional engines are also available through third-party manufacturers. These
engines often use a certain jargon or vocabulary. For example, they may use a
vocabulary that specializes in medical or legal terminology. They can also use
different voices allowing for regional accents such as British English or they
can use a different language altogether, such as German, French or Russian.
You need a microphone or
some other sound input device to receive the sound. In general, the microphone
should be a high quality device with noise filters built in. The speech
recognition rate is directly related to the quality of the input. The
recognition rate is significantly lower or may be unacceptable if you use a
poor microphone. The Microsoft Speech Recognition Training Wizard (Voice
Training Wizard) guides you through the process, recommends the best position
to place the microphone and allows you to test it for optimal results.
After you have installed
the system and it is working, you must train the engine for your environment
and speaking style. To do so, click the Speech Recognition tab, click Train
Profile and then follow the instructions in the Voice Training Wizard to train
the system to recognize background noises, such as a fan, air conditioning or
other office sounds. The engine adapts to your speaking style, including
accents, pronunciations and even idiomatic phrases.
Why do we use
The reason is simple.
Most people can speak much faster than they can type. A relatively fast typist
who can type 50 net words per minute can produce a 300 word e-mail in six
minutes. Using speech recognition software, a person dictating 140 to 160
words per minute without any errors can produce the same 300 word e-mail in
roughly two minutes.
Traditionally viewed as
simply a means of dictating text into a personal computer, today’s speech
recognition software can play a far more significant role in the healthcare
environment. In addition to pure dictation, speech recognition software can be
used to manage e-mail, streamline repetitive tasks on the PC, reduce
transcription and charting costs, speed up information turnaround and protect
employees from repetitive stress injuries (RSIs).

When you train the
Speech Recognition Engine, the speech recognizer uses the Voice Training
Wizard to adapt to the sound of your voice, word pronunciation, accent,
speaking manner and even new or idiomatic words. If you train for as little as
ten minutes, you can improve speech recognition capabilities. The system also
adapts to your speech on an ongoing basis and recognition increases over time.

2. Click the Speech Recognition tab and then click the Speech
Recognition Engine that you want to use in the Language box.
3. Click the profile that you want to use in the Recognition Profile group.
Training is specific to an engine and profile so that training one engine or
profile set has no effect on any other engine or profile set.
4. Click Train Profile and then follow the directions in the
Voice Training Wizard. Not all engines support training. If your engine does
not, Train Profile is unavailable.
