C H A P T E R 1 3 Improving Accuracy
Dragon NaturallySpeaking User’s Guide 169
The completely accurate speech-recognition system is an unattainable
ideal. You’d have to:
■ always speak clearly and articulate each word,
■ sound exactly the same at all times and on all days,
■ have trained Dragon NaturallySpeaking ® to recognize your voice
exactly as it is at any given moment,
■ keep the microphone exactly the same distance from your mouth
and always in the same position,
■ use an ultra-high-fidelity microphone that transmits sounds exactly
as you say them,
■ use a sound card that faithfully converts the microphone signal to
digital form,
■ speak only words Dragon NaturallySpeaking ® has heard before,
■ compose only sentences similar to ones Dragon NaturallySpeaking ®
has heard before,
■ have the fastest available processor in your computer,
■ have at least 256 MB of RAM,
■ have a hard disk with enough free space,
■ work in a quiet room,
■ have no radio interference or electrical noise from power lines.
Many of these conditions are impossible to achieve. No voice, for
example, always sounds the same and no microphone reproduces sounds
100 percent accurately. Other items are impractical or unlikely to be
available at the same time.
Some practical ways to improve
accuracy
Speak clearly
Speaking clearly and articulating each word is essential to getting a high
level of accuracy. The truism “garbage in, garbage out” applies here.
The clearer your speech, the better Dragon NaturallySpeaking
® will
guess what you said. If you mumble and slur your words, you’ll get many
errors. (See “Speaking and Dictating” on page 143.)
