Is VOX supposed to work in Windows XP?

I get the following error.

error turning recognition on:/r/nSystem.ArgumentException: Value does not fall within the expected range.
   at System.Speech.Internal.SapiInterop.SapiProxy.MTAThread.Invoke2(VoidDelegate pfn)
   at System.Speech.Internal.SapiInterop.SapiRecognizer.SetInput(Object input, Boolean allowFormatChanges)
   at System.Speech.Recognition.RecognizerBase.SetInputToDefaultAudioDevice()
   at System.Speech.Recognition.SpeechRecognitionEngine.SetInputToDefaultAudioDevice()
   at VoxCommando.Main.TurnSpeechRecognitionOn()

I tried using a mic and also the ps3 eye without sucess.

No, sorry. VoxCommando doesn't work with xp.  You need vista or win 7.
