This topic explains how to use the Exchange Management Console and the Exchange Management Shell to configure Automatic Speech Recognition (ASR) for a Microsoft Exchange Server 2007 recipient who is enabled for Unified Messaging (UM). When ASR is enabled on the mailbox of an Outlook Voice Access user, the user can move through the mailbox menus by using voice commands. If ASR is disabled, the user must use dual tone multi-frequency (DTMF), also known as touchtone, inputs to move through the mailbox menus. If the user tries to use voice commands when ASR is disabled, the system will ignore the voice command and wait for DTMF input from the user. However, an Outlook Voice Access user who is speech-enabled must always use the telephone keypad to enter their extension number, PIN, and to configure their personal options. Personal options that a user might configure include recording a voice mail greeting, changing a PIN, or changing their local time zone.

For ASR to work for an Outlook Voice Access user, the language that is configured in Office Outlook Web Access must contain support for ASR. Although ASR is currently available only in English, ASR support for other languages is planned for a future release.

Before You Begin

To perform the following procedures, the account you use must be delegated the Exchange Recipient Administrator role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

Also, before you perform these procedures, confirm the following:

  • The Exchange recipient has an Exchange 2007 mailbox.

  • The Exchange 2007 recipient is enabled for UM.

  • A UM dial plan has been created.

  • A UM mailbox policy has been created.

  • The extension number that is assigned to the UM user is valid according to the UM dial plan that is defined.


To use the Exchange Management Console to configure ASR for a UM-enabled user

  1. In the console tree of the Exchange Management Console, expand the Recipient Configuration node.

  2. In the result pane, select the user's mailbox that you want to view.

  3. In the action pane, click Properties.

  4. On the Mailbox Features tab, click Unified Messaging, and then click Properties.

  5. On the Unified Messaging Properties page, select Enable for Automatic Speech Recognition.

  6. Click OK to accept your changes.

To use the Exchange Management Shell to configure ASR for a UM-enabled user

  • Run the following command:

    Copy Code
    Set-UMMailbox -Identity -AutomaticSpeechRecognitionEnabled <$true | $false>
