New To Robots

I just received my Wall-e Toy and took it apart. I started to add some servos, and thought to try the Builder Project Examples. Wall-e big. I tested the Dance and it worked. I tried the Voice Recognition and it didn't respond. I have Windows 8 and tested my Voice Recognition. It works well on the computer but not in the builder. Like I said I'm new to Robotics and trying to learn the basics. Any Help will be appreciated.
