I think I know what chip you are reffering to. A couple years ago, I saw
some schematics in "Commodore" magazine about how to build a voice
controlled joystick with that chip. I have since lost the magazine, and I
never got around to building it, (heh), but in the article it said it
worked pretty good.
 
If you are going to use speech in VR, why not use one of the voice
recognition systems out already? Like Voicemaster by Covox or something?
