How to interface speech recognition using a PC to control a robot?

Hey there brilliant Engineers or soon to be engineers out there. I would like to ask whether is it possible to interface speech recognition technique to control a robot via a computer which can be desktop or laptop. Cause from what I found out so far it seems as though most people would use some sort of a speech kit. I'm currently in my final semester of my diploma and this is part of my final year project. Can I have some inputs here? Because if we were to use the speech kit instead it would most probably exceed our project budget.
