Recognition from multiple wav files... only last file gets
recognized

Hello!

I wan't my program to recognize the text from multiple wav-files in a
folder (file by file) in C#.

But with my code only the LAST file of my array is getting recognized.
Why aren't the Recognitions made one after another?

I don't get it.
Maybe someone of you people has an idea.


I tried it this way:
**************
....
this.wavarray = Directory.GetFiles(".\\" + title, "*.wav");

for (int i = 0; i < this.wav.Length; i++)
{
    this.sfile = wavarray[number].ToString();			// number is 0 at this time
    Console.WriteLine(sfile);
    recognize(this.number);

    this.number++;
}

public void recognize(int number)
  {
     engine = new SpeechRecognitionEngine();
     engine.SetInputToWaveFile(this.questionarray[number].ToString());
     engine.LoadGrammar(new DictationGrammar());
     engine.RecognizeAsync(RecognizeMode.Multiple);

     engine.SpeechRecognized += new 
EventHandler<SpeechRecognizedEventArgs>(engine_SpeechRecognized);		// 
write result to txtfile

     engine.AudioStateChanged += new 
EventHandler<AudioStateChangedEventArgs>(engine_AudioStateChanged);		// 
catch the "Stopped"-state
