When i use SpeechSynthesizer class in C# I get all voices installed in my system. When i use COM-object-based SAPI in C++ I get only 4 of them (Microsoft Anna and 3 other from Microsoft).

Why is this happening? I want to use Acapela voice in C++(QT), is it possible? If Yes, how?

P.S. Sorry for my English.

    Use SysInternals' ProcMon to see SAPI look through the registry for the voices. SpeechSynthesizer also uses SAPI so some odds that you'll see something else if you compile your C++ code to 64-bits. Contact the voice vendor if you need more assistance. – Hans Passant Nov 08 '13 at 19:13

Acapela voices are notorious for not having 64 bit support. If you build your C++ app in 32 bit mode (Project menu/Properties/Platform - make sure it's set to Win32, and not x64), you should be able to see the Acapela voice.
