Unified Messaging (UM) language packs allow an Exchange Server 2016 UM server to speak additional languages to callers and recognize other languages when callers use ASR or when voice messages are transcribed. UM language packs contain:
- Pre-recorded prompts, for example “After the tone, please record your message. When you’ve finished recording, hang up, or press the # key for more options.” in the language of the UM language pack.
- Grammar files that are used by a UM server to lookup the names of given users in the directory in the language of the UM language pack.
- Text to Speech (TTS) translation so that content (e-mail, calendar, contact information, etc.) can be read to callers in the language of the UM language pack.
- Support for Automatic Speech Recognition (ASR), which allows callers to interact with UM using the voice user interface (VUI) in the language of the UM language pack.
- Support for Voice Mail Preview which allows users to read the transcript of voice mail messages in a specific language from within a supported e-mail client such as Outlook or Outlook Web Access.
