Russian language recognition in Microsoft Speech API - sapi

Question

I would like to play a little bit with Microsoft Speech API. I have found this answer and it works! I have tried to adopt it to recognize Russian language. The grammar file look like this:
<GRAMMAR LANGID="419">
<DEFINE>
<ID NAME="TEST" VAL="1"/>
</DEFINE>
<RULE NAME="TEST" TOPLEVEL="ACTIVE">
<L>
<P>Привет</P>
<P>Пока</P>
</L>
</RULE>
</GRAMMAR>
The code is taken from the mentioned answer. But I get an error: the line
HRESULT hr = cpRecoGram->LoadCmdFromFile(L"D:\\data\\test\\reco_ru.cfg", SPLO_STATIC);
returns 0x80045052 (-2147200942): An attempt to load a CFG grammar with a LANGID different than other loaded grammars.
Is it possible to set up a program and/or an environment to use grammar files for Russian?
Environment: Windows 10 Home, Visual Studio 2017

Answer 1

Windows 10 does not ship a SAPI-compatible Russian recognizer as part of the OS. (There are en-US, en-GB, fr-FR, de-DE, ja-JP, zh-CHS, and zh-CHT SAPI recognizers available.)
However, if you're willing to use the Server recognizers (AKA the MS Speech Platform 11), you can find Russian recognizers at http://www.microsoft.com/en-us/download/details.aspx?id=27224.
You want the MSSpeech_SR_ru-RU_TELE.msi download.
The Server recognizers have a similar API, but don't support a number of features that the SAPI 5.4 recognizers support (namely, dictation).

Answer 2

For Russian
CComPtr<Speechlib_tlb::ISpRecoGrammar> cpRecoGrammar;
......
hr = cpRecoContext->CreateGrammar(1,&cpRecoGrammar);
hr = cpRecoGrammar->SetGrammarState(SPGS_DISABLED);
hr = cpRecoGrammar->ResetGrammar(0x0419);
HRESULT hr = cpRecoGram->LoadCmdFromFile(L"D:\\data\\test\\reco_ru.cfg", SPLO_STATIC);
hr = cpRecoGrammar->SetGrammarState(SPGS_ENABLED);

Answer 3

**for MS Speech Platform 11**
#define WM_RECOEVENT WM_USER+190
CComPtr<Speechlib_tlb::ISpRecoGrammar> cpRecoGrammar;
......
hr = cpRecoContext->CreateGrammar(1,&cpRecoGrammar);
hr = cpRecoGrammar->
SetGrammarState(Speechlib_tlb::SPGRAMMARSTATE::SPGS_DISABLED);
hr = cpRecoGrammar->ResetGrammar(0x0419);
hr = cpRecoGrammar-> LoadCmdFromFile(L"W:\\GrSR.cfg",
Speechlib_tlb::SPLOADOPTIONS::SPLO_STATIC);
hr = cpRecoGrammar->
SetGrammarState(Speechlib_tlb::SPGRAMMARSTATE::SPGS_ENABLED);
hr = cpRecoGrammar->
SetRuleState(NULL,NULL,Speechlib_tlb::SPRULESTATE::SPRS_ACTIVE);
hr = cpRecoContext->SetNotifyWindowMessage
((Speechlib_tlb::_RemotableHandle*)hWnd, WM_RECOEVENT, 0, 0)
