Заметки

This method considers all flags and factoid, among other things, that give context to the string that is being tested.

The IsStringSupported method checks the System dictionary, user dictionary, and WordList depending on whether speech is enabled in Microsoft Office. The following table lists the places the Recognizer checks for the specified string.

WordList condition	Microsoft® Office speech recognition is enabled	Microsoft® Office speech recognition is not enabled
WordList is set	WordList	WordList
WordList is nullссылка null (Nothing в Visual Basic)	User Dictionary and System Dictionary	System Dictionary

Use the Factoid property to limit the search to the system dictionary or the word list that is associated with the context. For example, to limit the search to the system dictionary, specify the SystemDictionary factoid. To improve the results, you may also need to set the RecognitionFlags property.

Примеры

In this example, a RecognizerContext object is instantiated, and a new WordList object assigned to its WordList property. The IsStringSupported method is then used to determine if a specified string is supported. If not, the string is added to the WordList.

Dim RC As RecognizerContext = New RecognizerContext()
RC.WordList = New WordList()
Dim testStr As String = "thunk"
If Not RC.IsStringSupported(testStr) Then
    Dim WL As WordList = RC.WordList
    WL.Add(testStr)
    ' testStr is not available for use in recognition
    ' until the WordList property is re-assigned
    RC.WordList = WL
End If

RecognizerContext RC = new RecognizerContext();
RC.WordList = new WordList();
string testStr = "thunk";
if (!RC.IsStringSupported(testStr))
{
    WordList WL = RC.WordList;
    WL.Add(testStr);
    // testStr is not available for use in recognition
    // until the WordList property is re-assigned
    RC.WordList = WL;
}
