Dear Experts,
  This is really a two part question.  First off, is it possible to create a voice recognition program using Visual Basic 5.0?  If so, does anyone know of any books or sites that give examples of how to do such a thing?  I will be raising point value of this question if I find out it is possible.

I say a book once I can't remember the name now that told how to do speech recognition in VB5.0
Unfortunately I didn't pick it up at the time.  It was a pretty cool book that talked about a lot of different cool features like that (encryption, speech recognition, etc.)
I can tell you that it used a standard set of Windows APIs to accomplish the feat.

Jagar,
  Although your reply didn't help me much in actually accomplishing the feat, you did tell me it was possible.  Because of this, I am raising points for an example or site.

Download the Speech SDK 4.0 Suite at http://research.microsoft.com/msrinfo/demodwnf.htm and look at the samples. There are several sample VB 5.0 source programs, plus C++ and Java if you are interested. The samples include VB 5.0 apps that speak, listen, or both.
Speech and recognition are handled by .OCX's that you place on a form. No API calls are required. The controls work just like using a text box only there is no visual component and the user uses a microphone instead of the keyboard. You give the control the text to speak and it says it. An event fires (if listening is enabled) when the control hears a phrase and it gives you the phrase in a string or will return it one word at a time.
Unfortunately, the web site does not provide the samples or documentation without performing the download and installation, which is time consuming depending on your PC and network capabilities. Be prepared for a download of about 40 MB and a 100 MB install.
