This topic explains how to use the Exchange Management Console and the Exchange Management Shell to speech-enable your UM auto attendant in Microsoft Exchange Server 2007 Unified Messaging (UM). By speech-enabling a UM auto attendant, you enable callers to respond verbally to auto attendant prompts and to move through the menu system of the auto attendant.
By default, an auto attendant is not speech-enabled when you create it. After you speech-enable the auto attendant, callers can use only voice commands to navigate the auto attendant menu system, and touchtone inputs cannot be used. Although it is not required, we recommend that you configure a dual tone multi-frequency (DTMF) fallback auto attendant for each speech-enabled auto attendant so that callers can use touchtone inputs if the speech-enabled auto attendant does not recognize or understand the words they say. If a DTMF fallback auto attendant is configured, the caller uses DTMF inputs, also known as touchtone inputs, to navigate the auto attendant menu system, spell a user's name, or use a custom menu prompt. We recommend that you do not speech-enable a DTMF fallback auto attendant.
Unified Messaging language packs include a Text-to-Speech (TTS) engine and the prerecorded prompts for the given language. However, only the English UM language pack includes support for Automatic Speech Recognition (ASR). ASR is used for directory lookups and searches. It is also used by Outlook Voice Access users and by callers when they use voice commands to interact with a UM auto attendant. ASR support for other languages is planned for a future release of the UM language packs. ASR support for English is installed when you install either the English version of Exchange 2007 or a localized version of Exchange 2007. The English language pack cannot be removed unless you remove the Unified Messaging server role from the Exchange 2007 computer.
|UM language packs are offered in 16 different languages, and all 16 language packs are included on the Exchange 2007 DVD. For more information about Unified Messaging language packs, see Understanding Unified Messaging Languages.|
