ACO analyzes a provider’s speech patterns and applies this analysis to the acoustic model. You can schedule ACO to run weekly, monthly, or at another interval. ACO runs for a particular provider as soon as the system has collected at least four minutes of dictation audio. At the next scheduled interval, the ACO runs again if the system detects any new audio, regardless of length; the process uses all the accumulated audio. The system repeats this cycle until it has processed five hours of audio for this provider; at that point, one hour of the stored audio is cleared and the collection cycle begins again.
LMO extracts words from signed reports and places them in the language model so as to improve speech recognition. LMO runs as soon as the system has collected at least one hundred characters of a provider’s report text; the process is repeated at the next interval.
ACO and LMO run at the intervals you specify. You can set the intervals for the entire system and for individual users.
The current recommendations for ACO and LMO are as follows:
ACO: At the system level, schedule the process to run weekly. When the software has accumulated the first five hours of a particular provider’s audio, change that provider’s schedule to run the process monthly. (At sites with over 100 users, you might want to configure individual providers to run ACO monthly after they have accumulated two hours of audio.)
LMO: At the system level, schedule the process to run daily; this job runs very quickly and does not consume many system resources.
It is recommended that you not schedule specific time slots for ACO. If you define daily windows for the ACO process, it can run only during the specified periods. Furthermore, even if the process is ready to run at the specified time, other jobs with higher priority might prevent it from running during that time frame.
To allow ACO to run at any time, do not set the time windows; leave all of the ACO Daily Windows fields blank. The system prioritizes jobs based on when the ACO was last run.
Leaving the ACO time parameters blank does not disable the process, but removes any limitations on when it can run. If you need to disable ACO, select Disabled as the Dragon ACO Interval.
To schedule ACO and LMO for all users:
1. In the Setup group, select the System tab.
2. Click Preferences, and then select the ACO/LMO tab.
3. Set the Dragon LMO Interval to your preferred interval. The recommended setting is Every day.
4. Set the Dragon ACO Interval to your preferred interval. The recommended setting is Weekly.
5. Click Save and Close.
To schedule ACO and LMO for an individual user:
1. In the Setup group, select the Accounts tab.
2. Select the provider whose optimization schedule you want to modify.
3. Click Preferences, and then select the ACO/LMO tab.
4. Set the Dragon LMO Interval to your preferred interval. It is recommended that you leave this setting at Every day.
5. Set the Dragon ACO Interval to your preferred interval. Once this provider has accumulated the first five hours of audio (two hours at large sites), you should change the interval to Monthly here.
6. Click Save and Close.
To view a user’s LMO and ACO activity:
1. In the Setup group, select the Accounts tab.
2. Select the provider whose LMO and ACO activity you want to view.
3. Click Audit. The Account Events window for this user opens.
4. If desired, select search criteria to narrow the list:
a. Select a Type of event from the drop-down list. For example, to see ACO events, select Optimize Speech Acoustics. The table shows the event types related to ACO and LMO.
b. Select a period of time from the Time Frame drop-down list. Or, to enter a date range, click Custom, select the start date from a calendar to insert it in the first text box. Then click the second text box and select an end date from the calendar. To revert back to choosing a time frame from a list, click List.
c. Select Account from the Events drop-down list.
d. Click Search. Any events that meet your criteria appear in the list.
Look for Speech Utility in the Realm column to find ACO or LMO-related events. You can click the Realm column heading to sort the list by this column.
5. When you have finished reviewing the LMO and ACO events for this account, click Close Window.
TIP: You can also use the ACO/LMO tab in the Logs group to view LMO and ACO activity.
