CHAPTER 13 Improving Accuracy 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 172 Dragon NaturallySpeaking User's Guide
