eTIP1Did you know Dragon Medical Network Edition provides users with the option to work without network connectivity?
 

INTENDED AUDIENCE: ALL USERS
LEVEL: BASIC 

 

When this option is enabled, Dragon uses the local cache as opposed to the network. This option is best suited if the network is slow or if you would like to dictate at home without network connectivity. Dragon is able to work in "disconnected mode" for a sum of 90 days. After this timeframe, Dragon will not allow access until re-authentication to the network. At any time it is possible to reset this 90 day timeframe by re-authenticating back to the network.

 

 The following must be in place before using the work offline feature:

  • An administrator must disable the Remove Local Cache After Usage option in the Nuance Management Console. Contact your site administrator for further information.
     
  • You must have logged in at least one time prior to setting the work offline option.
     
  • You must have downloaded your user profile from the master copy at least once. This ensures that you have a local copy of your user profile to work with when you are offline.

Perform the following to work offline:

  1. Launch Dragon Medical.
     
    Login to DM
     
  2. In the Dragon Login dialog box enter you login name and password.
  3. Check the box to enable the setting, "If you know your network is slow, enable this option to work offline."
  4. Click the Log In button to login to Dragon Medical in offline mode.

eTIP2Did you know that Microsoft Windows power-management features in portable computers such as laptops, notebooks, and tablets can dramatically create performance issues when using Dragon Medical?

 

INTENDED AUDIENCE: ALL USERS
LEVEL: BASIC 

 

Running these power-management features may trigger performance problems because processors in portable computers will dynamically change the performance-mode.  If your mobile device runs in a low-performance mode, this may not provide enough processing power to properly use / could generate erratic behavior in Dragon Medical. 

 

To prevent / correct these issues, use the following guidelines. NOTE: These guidelines apply only to portable computers such as laptops, notebooks, and tablets. 

  

Windows XP:

Set the power scheme to Always On.  To do this, follow these steps:

  1. Open Control Panel, and then double-click Power Options.
  2. Click the Power Schemes tab.
  3. Under Power Schemes, click Always On.
  4. Click both Ok buttons.
  5. Shut-down the portable device and restart.

Windows Vista & Windows 7:

Set the power plan to High Performance.  To do this, follow these steps: 

  1. Open Control Panel, and then double-click Power Options.
  2. In Windows Vista you'll see three preferred power plans to choose from: Balanced, Power Saver, and High Performance.
  3. Click High Performance.
  4. Close the Power Options screen and save all changes.
  5. Shut-down the portable device and restart.

NOTE:  Always on (Windows XP) and High Performance (Windows Vista and Windows 7) Power Schemes runs the CPU in its highest performance state.  It should be noted that by maximizing the performance state by altering these Power Schemes on a portable computer, this may greatly reduce battery life and cause the portable computer to run more warmly.

eTIP3Did you know that the Master User Profile Directory settings must be configured within NMC Console under the site settings in order for Dragon Client to connect with the NMS Server?

    

INTENDED AUDIENCE: POWER USERS OR SYSTEM ADMINISTRATORS

 LEVEL: INTERMEDIATE

 

We wanted to point out a frequently overlooked configuration setting relating to initial configuration of the Nuance Management Console. This configuration relates to the Master User Profile directory location.  Make certain to follow the below steps to ensure you have properly configured the Master User Profile Directory.  

  1. Login to the NMC Console page.  
  2. Select Organization Overview under the Sites tab.
  3.  Double click on the Site to access the settings.  To create a new site, simply click on Add Site.
  4. Click on the Dragon Settings tab and select Master use profile.
  5. Click on Configure... to configure the roaming path location and the NMC UNC Path location.
  6.  Press Ok and Save to save and exit the Sites configuration. 

Click the play button on the following eTIPS Video for a demonstration on how to properly configure the Master User Profile Directory.

eTIP4eTIPS4Did you know about the mechanics of how Dragon Medical maintains high speech recognition accuracy? 
 

INTENDED AUDIENCE: POWER USERS OR SYSTEM ADMINISTRATORS
LEVEL: INTERMEDIATE
 

Speech Recognition occurs when Dragon Medical analyzes an incoming stream of sounds and interprets them as dictation and commands.  Each recognized word has a text representation (Written Form) and a pronunciation (Spoken Form) representation.  Dragon's success at recognition accuracy is measured by % of correct interpretations, or conversely, a low Word Error Rate (WER). 

 

To achieve high recognition accuracy, Dragon Medical relies on several data source models when a user profile is first created and trained (enrolled):

  • Acoustic Model - A mathematical model of sound patterns used by a speaker's language
     
  • Vocabulary - A list of words that Dragon will recognize for this user
     
  • Language Model - Statistical information associated with a vocabulary that describes the likelihood of words and sequences of words occurring in user's speech, based on Dragon Medical's best educated guess within a specific speech pattern context

Some reasons why Dragon Medical may not properly recognize the Spoken Form of a word are listed below in order of importance: 

  1. The correct word does not exist in the user's vocabulary.  In this case, be sure to have the user add uncommon words/phrases to their vocabulary. 
     
  2. The correct word is misrecognized.  This is compounded when the user does not correct the misrecognition using proper correction methods employed by Dragon Medical. 
     
  3. The Acoustic and Language Model Optimization is not being performed on a regular basis.  Nuance makes a strong recommendation to run Dragon Medical's Acoustic and Language Model Optimization on a weekly schedule.
      
  4. The acoustic calibration for the input device (microphone) is not accurately set using Dragon Medical's Audio Setup Wizard. 
     
  5. The pronunciation of the Spoken Form for the correct word/phrase was too close to the pronunciation of the recognized (but incorrect) word/phrase.
      
  6. Accidental or ambient noises were interpreted and recognized as words.
In addition, Dragon Medical may correctly recognize the Spoken Form of a word, but not interpret the Written Form as expected.  This can occur when the Dragon Medical Formatting rules are not configured to a user's expectation.
