Syntax

'Declaration
Public Function IsStringSupported ( _
    s As String _
) As Boolean
'Usage
Dim instance As RecognizerContext
Dim s As String
Dim returnValue As Boolean

returnValue = instance.IsStringSupported(s)

public bool IsStringSupported (
    string s
)

public:
bool IsStringSupported (
    String^ s

    s : String
) : boolean

Not applicable.

Parameters

s
The string to look up in the dictionaries and word list.

Return Value

A value that indicates whether the system dictionary, user dictionary, or WordList contain a specified string.

Value	Meaning
true	The string is in the dictionary or word list
false	The string is in neither the dictionary nor the word list

Remarks

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 a null reference (Nothing in 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.

Example

This C# example uses the IsStringSupported method to query the WordList object that is used by the RecognizerContext object, theRecognizerContext, for a specific string, "thunk". If "thunk" is not in the word list, it is then added to the word list.

String theString = "thunk";
WordList theWordList = theRecognizerContext.WordList;
if (!theRecognizerContext.IsStringSupported(theString))
{
theWordList.Add(theString);
    theRecognizerContext.WordList = theWordlist;
}

This Microsoft® Visual Basic® .NET example uses the IsStringSupported method to query the WordList object that is used by the RecognizerContext object, theRecognizerContext, for a specific string, "thunk". If "thunk" is not in the word list, it is then added to the word list.

Dim theString as String
theString = "thunk"
Dim theWordList As WordList
Set theWordList = theRecognizerContext.WordList
If Not theRecognizerContext.IsStringSupported(theString) Then
    theWordList.Add(theString)
    TheRecognizerContext.WordList = theWordList
End If
