Chapter 5: Installing Dragon using the Windows installer (MSI)
Revising Day/Time of Scheduled
Tasks (Optional)
This section describes how to modify the schedule for Dragon tasks to later take place on each dic-
tation client computer by passing particular options in a command line installation. This section is
a continuation of Installation using the Dragon command line. When you finish this section, you
might want to proceed to Configuring Local or On-Demand Install of Vocabularies/Text-to-
Speech (Optional).
Note: You take the following actions on the client computer to install Dragon on client PCs, not
on the computer where you installed the initial installation and configured default option settings
for users.
You can include an additional option on the command line to indicate you want on any or all of
the following tasks carried out on a particular schedule:
n Acoustic model optimization (ACO) — This task optimizes the acoustic files used to recognize
words that the user trains and speaks. 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, after the speaker has worked with Dragon for a while.
n 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, ultimately customizing the model for
that user profile.
n 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.
You turn on/off the above tasks and set the schedule for those you turn on by passing an option
called PERIODIC_TASK to the MSI installer. You set PERIODIC_TASK to a string containing
short acronyms for the types of tasks, aco | lmo | dc, separated by vertical bars. If you do not
pass the acronym for the feature, that feature is set to its default.
After the acronyms for the tasks to schedule, the string for PERIODIC_TASK should include the
administrator login and password, then the schedules that correspond to the acronyms, in the
order that they occur in the string. The schedules use three-letter weekday abbreviations and 24-
hour time with two digits for the hour and two for the minute, separated by a colon. The two
schedules are separated by vertical bars and presented in the same order as their corresponding
acronyms. While the acronyms for the tasks are separated from each other by vertical bars, sem-
icolons separate the group of tasks from the admin user name, password, and group of schedules.
For instance, to retain the default schedule for data collection and modify schedules for acoustic
model optimization to Mondays at 1 AM and language model optimization to Mondays at 6 AM,
you would set PERIODIC_TASK as follows:
PERIODIC_TASK="aco|lmo;admin;pswd;Mon, 01:00|Mon, 06:00"
An installation command line including this task setting option might look like the following:
