Update the Speech Grammar Files on a UM Server
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
You can update the Automatic Speech Recognition (ASR) grammar files for Microsoft Exchange Server 2010 Unified Messaging (UM). Speech grammar files have a file name extension of .cfg and are used by Unified Messaging to enable callers to use speech inputs to perform directory lookups. A folder for each UM language is created in the <Program Files>\Microsoft\Exchange Server\V14\UnifiedMessaging\grammars folder. Each UM language-specific folder contains the grammar files for the given language that are used for Outlook Voice Access. The language-specific folders also contain the grammar files generated by the Microsoft Exchange Unified Messaging service for the global address list, custom address lists, UM dial plans, and UM auto attendants.
