You do realize that VARBINARY[^] is limited to 8000 bytes, don't you? That is a pretty small .WAV sample.

You should consider using IMAGE[^] instead.

As far as doing the "voice comparison", I would suggest you start with Google[^]

Voice comparison is a difficult and somewhat uncertain matter. What's the criteria for the records to be closed? You did not mention any, as well as your goal.

What if you need only speech recognition? In this case, you can store just the recognized text in the database and try to recognize the speech sent by the user. For this purpose, use either System.Speech.SpeechRecognitionEngine or System.Speech.SpeechRecognizer, see http://msdn.microsoft.com/en-us/library/system.speech.recognition.aspx[^].

Sorry if my idea does not address your problem. I don't know the purpose of what you want, so that was just my guesswork.

If you want to compare something like melodies or musical pieces of individual voice characteristic, it would be too complex a task which needed a lot of research, perhaps even of your whole life time. :-)
