Property Value
Type: Microsoft.Speech.Recognition..::..DisplayAttributesSpecifies the use of white space to display of the contents of a RecognizedWordUnit object.
Remarks
The DisplayAttributes object returned by DisplayAttributes specifies the leading and trailing spaces to be used with a given word.

Examples
The following example shows a utility routine (stringFromWordArray) that generates lexical output (using LexicalForm), normalized output (using Text), and phonetic text output (using Pronunciation). The text output is formatted by the use of DisplayAttributes objects obtained from the DisplayAttributes property from a ReadOnlyCollection of RecognizedWordUnit objects. The RecognizedWordUnit objects are obtained from the Words property on the RecognizedPhrase object.
