UM Language Packs for Exchange 2010 – Installation

With Unified Messaging (UM) language packs installed you enable callers and OVA (Outlook Voice Access) users to interact with the Unified Messaging system in multiple languages. Each UM language pack includes :

  • TTS engine (Tex-to-Speech)
  • ASR (Automatich Speech Recognition)
  • Voice Mail Preview

Installing UM Language packs for Exchange 2010 can be done in two ways. First you have to download the correct Exchange 2010 UM language packs. The UM langauge packs for Exchange 2007 cannot be used!

1. Install UM language pack through the GUI
Double-click the setup file UMLanguagePack.<language>.exe. In my case the Dutch version :
Accept the License Agreement, click next and make sure the correct language is displayed in the listed language packs that are going to be installed.
Click install to start the installation.

2. Install UM language pack through (command-line)
Using this method you can install multiple UM Language packs at once.
Place one (or multiple) language packs in a specific directory on your Exchange UM Server. ex. C:UMLanguagePack
Start a command prompt and go to : C:Program FilesMicrosoftExchange ServerV14Bin

Run the following command line : /AddUmLanguagePack:nl-NL /s:C:UMLanguagePack
For multiple language packs, add more languages and seperate them with a comma : /AddUmLanguagePack:nl-NL,de-DE /s:C:UMLanguagePack
