Dragon 12 Installation and User Guide
n Be sure that the "Store corrections in archive" option is selected on the Data tab of
the Options dialog box. Otherwise you may see a message that there is not enough
data for the Acoustic and Language Model Optimizer to process. The "Store cor-
rections in archive" option should be selected whenever you use Dragon for an
extended period of time.
n If you have a User Profile set to the Correction Only Mode (for example, a tran-
scriptionist), you must disable the Correction Only Mode option on the Miscellaneous
Tab of the Administrative Settings dialog box before running the Acoustic and Lan-
guage Model Optimize on this User Profile.
To run the Acoustic and Language Model Optimizer
1. Say "Switch to DragonBar," then "Audio," then "Launch Accuracy Tuning," or click
Audio> Launch Accuracy Tuning on the DragonBar.
The Acoustic and Language Model Optimizer dialog box opens with Perform Acoustic
Optimization and Perform Language Model Optimization selected. Nuance recommends
that you run both optimizations at the same time to maximize accuracy.
2. Click or say "Go" to start the Acoustic and Language Model Optimizer.
3. The Acoustic and Language Model Optimizer may ask if you want to save your current
User Profile. Click or say "Yes" if you made corrections since the last time you ran the
Acoustic and Language Model Optimizer, or if you have not run the Acoustic and Lan-
guage Model Optimizer since you started using Dragon.
The Acoustic and Language Model Optimizer dialog box shows Dragon's estimate of how
long it will take to finish adapting your User Profile. How long this takes depends on the
amount of Acoustic Data stored in your User Profile.
Notes
n By default, the amount of acoustic data saved is limited to 180 minutes (the max-
imum). You can reduce this amount on the Data tab of the Options dialog box.
n If you attempt to run the Acoustic and Language Model Optimizer before you have
trained any corrections (even if you have corrected errors without training the cor-
rections), or before you have performed any additional training, you will see an error
message saying that there is not enough data for the Acoustic and Language Model
Optimizer to process.
n Training multiple words or phrases rather than training individual words is generally
more effective at increasing accuracy. Most people have a tendency to over enunciate
when saying individual words as opposed to the more normal speech patterns of say-
ing a complete phrase.
n The Acoustic and Language Model Optimizer automatically makes a backup of the old
User Profile before it begins modifying them. Your User Profile is automatically
restored if you click Cancel before the Acoustic and Language Model Optimizer is fin-
ished.
