How to code a very simple "voice recognition" application?

How to code a simple "voice recognition" application that needs to recognize just a few words?

I've got a friend with multiple sclerosis who can't move below the neck. Most of what he does is listening to audio recordings or some radio or watch tv, but he is completely dependent on the people in the nursery home for changing the cd's. I only visit him twice a week.

My budget is very limited - I'm unemployed - so I thought about coding a simple voice recognition app that would recognize at least 3 different commands. Like "next", "ok", "cancel". With those commands I could than code some simple interface to select and play audio or even videos.

I can work with action script 2 (flash 8), and sometime in the past I remebered learning some vb 6. I remeber there are some thingies with like prebuilt functions that you drag into the coding environment that than allow you to do things. But from what I've googled voice recognition is a bit more complicated.

I got this file from here: http://www.codeproject.com/KB/audio-video/SAPI/Speech.zip but I have no idea where to start, any pointers?

I just need to understand how to get an application to recognize input from a microphone and distinguish between at least 3 different inputs.

Thanks

Simple and Voice recognition are two things that aren't mixed. I don't know for sure but I'm pretty positive that AS won't work, I could be wrong. I know Java would probably do it. And I know C++ would do it. But like I said simple is not something that would work with this type of project. There is a lot of logic and pattern recognition that goes along with VOICE RECOGNITION, so it's not *simple* and easy, it would take so doing and a very intense knowledge of any programming language.

At least that's my humble opinion and 10+ years of programming.
