Dragon Client Installation Guide
MSI options for scheduled tasks
Note: Take the following actions on the client computer. Do not perform them on the computer
where you performed the initial installation and configured default option settings.
You can include an additional option on the command line to run one or more of the following tasks on a
particular schedule:
l Acoustic model optimization (ACO)—This task optimizes the acoustic models used to
interpret the user’s speech. You can set a particular date and time for this optimization to occur.
When a speaker is new to Dragon, you might want to run the optimization more often.
l Language model optimization (LMO)—This task optimizes the language model (vocabulary
files) used to help recognize words that the user speaks. The model incorporates data from the
user’s speech into the language model he or she is using, customizing the model for that user
profile.
You can schedule acoustic and language model optimization tasks and turn them on or off by passing
the PERIODIC_TASK option to the MSI installer.
First, set PERIODIC_TASK to a string containing short acronyms for the types of tasks, separated by
vertical bars: aco | lmo | dc.
If you do not pass the acronym for a feature, that feature is set to its default.
Next, the string for PERIODIC_TASK should include the administrator login and password, followed by the
schedule for each task, in the order that they occur in the string, separated by vertical bars.
l
Enter the day(s) of the week for each task using three-letter abbreviations (Mon, Tue, etc.).
l
Enter the hour using a 24-hour clock in the format hh:mm (05:00, 18:30, etc.).
For example, the string below sets the schedule for Acoustic Model Optimization to Mondays at 1 AM
and the Language Model Optimization to Mondays at 6 AM:
PERIODIC_TASK="aco|lmo;admin;pswd;Mon, 01:00|Mon, 06:00"
The task runs once a week on the day and time indicated. If you omit the Day, the task runs every day at
the time given.
Default Schedules
l
Acoustic model optimization (ACO)—Every day, 3 AM
l
Language model optimization (LMO)—Every day, 2 AM
