C H A P T E R 1 3 Improving Accuracy
Dragon NaturallySpeaking User’s Guide 171
Use a good sound card
Your system’s sound card is as important as your microphone in
conveying a clear sound signal to Dragon NaturallySpeaking
® .
Upgrading to a high-quality microphone will show no accuracy
improvement if your sound card generates static or an insufficient signal
level.
You can test your sound system using the Dragon NaturallySpeaking ®
Audio Setup Wizard. See “Testing your sound system” on page 211 for
instructions.
Context
Dragon NaturallySpeaking
®
guesses what words you said from their
context as well as from the sound of your voice. If the words you say are
similar to what you’ve said before, the program tends to guess what you
say more accurately. Use the vocabulary tools in the Accuracy Center
(see “Tools to improve your vocabulary” on page 156) to teach Dragon
NaturallySpeaking
®
your writing style and what words you tend to use
most often. This will significantly improve its accuracy.
Processor speed, memory, and hard disk space
Processor power boosts recognition performance, though it’s less
important than context and a clear speech signal. A faster processor in
your computer lets the software make more calculations in the same
amount of time, so it can better hone in on what words you actually said.
For optimal results, the speech-recognition software should not have to
share processor power with any other programs running at the same time.
Your computer should have enough memory (RAM) to hold Dragon
NaturallySpeaking
®
and any other programs running at the same time.
The minimum recommended RAM for Dragon NaturallySpeaking
®
is
128 MB. If you have less than 128 MB of RAM, upgrading to 128 MB or
more may improve the software’s performance.
Hard disk space is relatively unimportant to program performance, as
long as you have about 500 MB free for the Windows
®
operating system
to use for temporary storage as you work.
