Advances in software techniques and processing power over the last decades have finally enabled speech recognition to be effectively used as a viable man-machine interface. This paper describes preliminary work on exploring effectiveness of voice commands and mouse interaction to solve the Hanoi problem. Our first results indicate that performance of speech and other kinds of human-computer interaction (mouse and button) are compatible and that speech-enabled virtual reality applications could be used to train impaired people to perform complex tasks today performed only by people with hand abilities.
