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.
l
Data collection (DC) — This task automatically collects data that helps improve Dragon’s
ability to recognize speech. You can choose to allow this data to be sent back to Nuance over
the Internet on a particular schedule, or choose not to send the data. This process does not
collect your personal information. Data collection is available in non-US English versions of
Dragon.
Note: When Nuance Management Center/NMS mode is enabled, you cannot schedule Data
Collection tasks on the Dragon client. NMC administrators can schedule Data Collection in the
NMC console. For more information, see the Nuance Management Center Administrator Guide.
You can schedule the above tasks and turn them on or off by passing an option called PERIODIC_TASK
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. Because no schedule is specified for Data Collection, the default schedule will be used
(Stand-Alone only).
Default Schedules
l
Acoustic model optimization (ACO)—Every day, 3 AM
l
Language model optimization (LMO)—Every day, 2 AM
