Implementation and Testing of Voice Control in a Mobile Robot for Navigation

Abstract

Recently, the usage of the assistive robots will become a common device interface with the voice recognition system and controlled by the common spoken languages. To control the robots by voice has always triggered the humans desired. The speech/voice recognition system becomes comfortable and important system to control the machines in today's life and become a one of the hot topic in the development of the assistive robots. In this paper, a voice control software system is integrated with the SLAM algorithm available in Robotic Operating Systems (ROS) and implemented to a mobile system of a robot "ROSWITHA". This paper also expresses the different ways of controlling the robot by developing a Graphical User Interface (GUI) with different controlling tabs including start navigation on created/available map, voice detection, enter the destination location and stop tabs for spontaneous abort of the system. The experiment and test is performed in a real-time and with different environments as well with different speakers to analyze the accuracy of the system. Herewith, this papers also describe the successful implementation of voice system with robot's movement according to humans spoken commands.
