Voice control of dual-drive mobile robots-survey of algorithms

摘要

Presents a survey of the algorithms applied to voice control of electromechanical appliances, especially voice controlled mobile robots or intelligent wheelchairs for handicapped people. The second part of the paper is devoted to voice recognition algorithms. Besides a short voice processing algorithms review, the need of voice recognition results verification method was pointed out. The method proposed by author is presented. In order to improve robotized-wheelchair operation safety and functionality, it is necessary to implement additional environment recognition sensors. Some issues concerning the ultrasonic sensors are referred to. The data acquired from the sensors can be used by obstacle avoidance and path planning algorithms. These categories of algorithms and methods are presented in fifth part of the paper. There is brief review of master control algorithms in the sixth section. In the last part the conclusions from the survey are listed.
