Example

The example below show a simple anonymousmethod used as the handler for RecognizeCompleted. The handler stores the result of the recognition operation, if Result is not null and updates a state variable. If an error condition exists, a message is sent to the end user.

_recognizer.RecognizeCompleted += delegate(object sender, RecognizeCompletedEventArgs completedEventArgs) {
    _recognitionDone = true;
    if (completedEventArgs.Result != null) {
        _completedEventArgs = completedEventArgs;
        _recognitionSuccess = true;
    } else {
        _completedEventArgs = null;
        _recognitionSuccess = false;
        MessageBox.Show(String.Format("Recognition failed\n",
                                      "InitialSilenceTimeout: {0}\n",
                                      "BabbleTimeout: {0}\n",
                                      "InputStreamEnded: {2}\n",
                                      completedEventArgs.InitialSilenceTimeout,
                                      completedEventArgs.BabbleTimeout,
                                      completedEventArgs.InputStreamEnded));
    }
};
