Send Feedback

This method handles an engine extension call to the SR engine. It behaves the same way as ISpSREngine::PrivateCall, except that it allows the engine to retrieve a data block of variable size for the engine extension object.

HRESULT PrivateCallEx(  void* pvEngineContext,  const void* pInCallFrame,  ULONG ulInCallFrameSize,  void** ppvCoMemResponse,  ULONG* pulResponseSize);

Parameters

  • pvEngineContext
    [in] Pointer to the speech recognition context for the engine. The pointer is retrieved by a prior call to the ISpSREngine::OnCreateRecoContext method.
  • pInCallFrame
    [in] Pointer to engine-specific input data.
  • ulInCallFrameSize
    [in] Size, in bytes, of the engine-specific data specified by pInCallFrame.
  • ppvCoMemResponse
    [out] Address of a pointer to the response block information from the SR engine. This must be allocated with CoTaskMemAlloc.
  • pulResponseSize
    [out] Pointer to the size, in bytes, of the data specified by ppvCoMemResponse.
