Why isn't the Microsoft voice appearing in Communicator?
Microsoft Speech
Communicator supports the SAPI5 voice format. SAPI5 is Microsoft Speech API 5. It was the Microsoft standard speech format for text to speech from Windows XP through Windows 8. Windows 10 introduced Windows Mobile Voices. There are many more Windows Mobile Voices that come with Windows 10 than SAPI5 voices. The Windows Mobile Voices are not compatible with Communicator and will not appear under the list of voices.
