C H A P T E R 1 3 Improving Accuracy
Dragon NaturallySpeaking User’s Guide 172
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.
Background noise
Dragon NaturallySpeaking ® performs best in a quiet room. In a noisy
office, accuracy may decrease slightly, though the program will still be
useful. For best results, train (or retrain) your user files in the same
environment in which you’ll be dictating.
Electrical interference
In some cases, noise in a building’s electrical wiring will generate static
in your computer’s sound card. Few desktop users encounter this
problem; it’s mostly limited to laptops, which have less isolation of
power source and sound card. If your laptop is performing slowly or
inaccurately, try unplugging it and run it only from battery power to
eliminate possible interference from the building wiring. Also, switch to
a USB microphone, if you are not already using one.
Using Dragon NaturallySpeaking
®
with other
software
When dictating into your word processor with no other programs
running, your computer’s power is dedicated to processing your speech.
If other programs are also open, your computer must divide its
processing power between processing your speech and other tasks. Some
