Example

The example below shows a utility routine (stringFromWordArray) that generates lexical (using LexicalForm), normalized (using P:Microsoft.Speech.Recognition.RecognizedWordUnit.Text), and a phonetic (using Pronunciation) text output (formatted using DisplayAttributes objects obtained from the DisplayAttributes property) from the a System.Collections.ObjectModel.ReadOnlyCollection of RecognizedWordUnit objects, which is obtained from the P:Microsoft.Speech.Recognition.RecognizedPhrase.Words property on the RecognizedPhrase object.

internal enum WordType {
          Text,
          Normalized = Text,
          Lexical,
          Pronunciation
}

internal static string stringFromWordArray(ReadOnlyCollection<RecognizedWordUnit> words, WordType type) {
          string text = "";
          foreach (RecognizedWordUnit word in words) {
              string wordText = "";
              if (type == WordType.Text || type == WordType.Normalized) {
                  wordText = word.Text;
              } else if (type == WordType.Lexical) {
                  wordText = word.LexicalForm;
              } else if (type == WordType.Pronunciation) {
                  wordText = word.Pronunciation;
              } else {
                  throw new InvalidEnumArgumentException(String.Format("[0}: is not a valid input", type));
              }
              //Use display attribute

              if ((word.DisplayAttributes & DisplayAttributes.OneTrailingSpace) != 0) {
                  wordText += " ";
              }
              if ((word.DisplayAttributes & DisplayAttributes.TwoTrailingSpaces) != 0) {
                  wordText += "  ";
              }
              if ((word.DisplayAttributes & DisplayAttributes.ConsumeLeadingSpaces) != 0) {
                  wordText = wordText.TrimStart();
              }
              if ((word.DisplayAttributes & DisplayAttributes.ZeroTrailingSpaces) != 0) {
                  wordText = wordText.TrimEnd();
              }

              text += wordText;

          }
          return text;
      }
