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.
For more information, see “System requirements” on page 9.
Improving speed
On all systems, there’s a delay between when you speak and when
Dragon NaturallySpeaking
®
types out what you said. Dragon
NaturallySpeaking
®
uses this delay time, plus the time when you’re
talking, to recognize your speech. The faster your processor, the shorter
the delay. Even with a speedy processor, though, Dragon
NaturallySpeaking
®
usually waits until you pause to type out what it
recognized.
Sound quality is at least as important as the processor speed in making
Dragon NaturallySpeaking
®
work quickly. If your microphone and sound
card combination make your speech sound fuzzy to the computer or if
they generate background hiss or static, Dragon NaturallySpeaking
®
will
have to spend much more time processing your speech to eliminate the
background noise. A clear microphone and sound card combination will
substantially boost speed as well as accuracy. The microphone included
with your software is a high-quality noise-canceling microphone.
