    HRESULT GetPhrase(SPPHRASE   **ppCoMemPhrase
);

Parameters

Example

The following code snippet illustrates the use of ISpRecoResult::GetPhrase as inherited from ISpPhrase to retrieve the recognized text, and display the rule recognized and the phrase.

  
// Declare local identifiers:
HRESULT                   hr = S_OK;
CComPtr<ISpRecoResult>    cpRecoResult;
SPPHRASE                  *pPhrase;
WCHAR                     *pwszText;
HWND                      hwndParent;

// ... Obtain a recognition result object from the recognizer ...

// Get the recognized phrase object.
hr = cpRecoResult->GetPhrase(&pPhrase;);

if (SUCCEEDED (hr))
{
   // Get the phrase's text.
   hr = cpRecoResult->GetText(SP_GETWHOLEPHRASE, SP_GETWHOLEPHRASE, TRUE, &pwszText;, NULL);
}

if (SUCCEEDED(hr))
{
   // Display the recognized text and the rule name in a message box.
   MessageBoxW(hwndParent, pwszText, pPhrase->Rule.pszName, MB_OK);
}
