ISpPhrase::GetText (SAPI 5.4)

Microsoft Speech API 5.4

ISpPhrase::GetText

ISpPhrase::GetText retrieves elements from a text phrase.

  
    HRESULT GetText(
   ULONG                                          ulStart,
   ULONG                                          ulCount,
   BOOL                                           fUseTextReplacements,
   [annotation ("__deref_out")] LPWSTR          **ppszCoMemText,
   [annotation ("__out_ecount_opt(1)")] BYTE     *pbDisplayAttributes
);

Parameters

• ulStart
  [in] Specifies the first element in the text phrase to retrieve.
• ulCount
  [in] Specifies the number of elements to retrieve from the text phrase.
• fUseTextReplacements
  [in] Boolean value that indicates if replacement text should be used. An example of a text replacement is saying "write new check for twenty dollars" and retrieving the replaced text as "write new check for $20". For more information on replacements, see the SR Engine White Paper.
• ppszCoMemText
  [out] Address of a pointer to the data structure that contains the display text information. It is the caller's responsibility to call ::CoTaskMemFree to free the memory.
• pbDisplayAttributes
  [out] Address of the SPDISPLAYATTRIBUTES enumeration that contains the text display attribute information. Text display attribute information can be used by the application to display the text to the user in a reasonable manner. For example, speaking "hello comma world period" includes a trailing period, so the recognition might include SPAF_TWO_TRAILING_SPACES to inform the application without requiring extra text processing logic for the application.

Return values

Remarks

The text is the display text of the elements for the phrase and constructs a text string created by CoTaskMemAlloc by applying the pbDisplayAttributes of each SPPHRASEELEMENT.

Example

The following code snippet illustrates the use ISpPhrase::GetText to retrieve parts of the recognized phrase.

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

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

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

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

if (SUCCEEDED(hr))
{
   // Get the phrase's first 2 words, excluding replacements.
   hr = cpRecoResult->GetText(pPhrase->Rule.ulFirstElement, 2, FALSE, &pwszText;, NULL);
}

if (SUCCEEDED (hr))
{
   // Do some more stuff.
}
