Abstract

Speech recognition technology could help an electrical wheel chair to run easily and safely. Up to now, two methods about command mode have been used for study. In this study, we proposed two new methods by combining good points of two conventional methods. A remote controlled car was made to run by voice instructions, along test course including straights, a right curve, a left curve, a right turn, and a left turn. New methods were compared with two conventional methods in terms of maneuverability and accuracy. It has beenproved that our present methods were superior because frequency of instruction was less and accuracy of running was excel.
