This articles goes through the options being greyed out when you try to configure the ODMS settings.
When the options are greyed out this means All User Settings was selected during the install as shown below. This means that all users on this computer will share the same settings but only the local administrator can configure settings.
Depending on your user account privileges you may be able to right click the Dictation Module and click Run as administrator to access the options setting. Otherwise you may need to contact your IT administrator to configure the software for you.
