How to use SAPI in metro

Question

I tried to use Speech API in metro but I just don't know how to do that.

First I tried building win32 DLL using SAPI and use it in Metro but failed - LoadPackagedLibrary returned error code 127 and I couldn't find detail information about it on the web.

Then I tried building static library but I couldn't include header file in Metro. It just returned bunch of errors for interfaces in sapi.h, for example CComPtr<ISpObjectToken>.

Finally, I tried create Windows Runtime Library, but I can't replace CComPtr to WRL::ComPtr.

Can anyone help me to use SAPI in Metro? Basically, I want to use speech recognition in Metro, not using Bing or web access.

Answer 1

SAPI is not supported in Windows Store apps. Sorry!

For speech recognition you'll have to use a web service (such as Bing's) or find a 3rd party solution (I'm not aware of any).

Answer 2

I heard that there are some ways to use Win32 APIs in Metro. Is there a specific reason that SAPI is not supported in Windows Store app? I'm just curious.
