Working with Permissions / Improving Speech Recognition for Frequently Called Users and Departments |
To take full advantage of the Frequently Called Departments feature to improve overall speech recognition for the Vocera system, Vocera recommends the best practices listed in this topic.
Optimize your Vocera system.
If your Vocera system is very large, you may need to do some performance tuning to optimize your system. A large Vocera system typically has more than 2,500 users across multiple sites and a spoken name count (which includes user names, group names, alternate spoken names, and department names) equal to or greater than 90,000. See Performance Tuning for Large Customers in the Vocera Voice Server Installation Guide.
Enable the Feature for Departments.
Make sure Favor Frequently Called enabled for departments on the System > Preferences page of the Administration Console. See Setting System Preferences for complete information.
Make sure all Vocera users are assigned to a department. Also, avoid nesting department groups.
To ensure that key users in a department are included in the speech recognition improvement and statistics, you must select Enable Frequently Called checkbox in each user's profile.
Users who are members of a department will benefit from speech recognition improvements due to the Favor Frequently Called option enabled for departments. All users who are not assigned to a department use a special speech recognition grammar file that is assigned a 5% probability.
Allow calling statistics to be collected for several weeks to determine reliable calling patterns for departments. Before calling patterns take effect, uniform probabilities are applied to departments. See Collecting Call Statistics for Frequently Called Departments for complete information
In the Administration Console, you can view calling statistics for Frequently Called Departments on the Dept Call Frequency tab of the Departments page. If department and subdepartment groups have experienced significant changes in membership due to restructuring of your Vocera database, you might consider clearing the calling statistics for a selected site or department. See Viewing Call Statistics for Frequently Called Departments for complete information
Speech Recognition Diagnostic Reports
To assess speech recognition for departments, use the Vocera Report Server to schedule several diagnostic reports, including Recognition Results by Department and Recognition Results by User. For more information, see the Vocera Report Server Guide.
