Supported Speech Language Packs

Microsoft Unified Communications Managed API (UCMA) 3.0 Workflow applications require installation of Microsoft Speech language pack(s) to use Speech Recognition and text-to speech (TTS). Microsoft Speech Recognition and TTS language packs are available in different languages. By default, the UCMA installer only installs support for DTMF, and en-US speech recognition and TTS engines. Additional languages should be downloaded from the Microsoft Download Center.

From the Microsoft Download Center, download the Microsoft Lync Server 2010 UCMA 3.0 Speech Language Pack which supports the language of your workflow application.
