Abstract
Human–robot interaction has been a challenging task, and it involves various criteria to be considered including robot operator’s caliber and his/her safety. Here in this project, we bring speech recognition to the rescue of robot operator, which has become a popular interface for human–computer interaction to recognize the speech of robot operator, to command and control the industrial robot. In this project, the five degree of freedom robotic arm is controlled through speech-based interfaces in Indic Languages, namely English (Indian accent), Hindi and Tamil. Python speech recognition API along with PocketSphinx is used for converting robot operator’s speech commands to text form, and the command is translated and fed to the sophisticated servo controller for the actuation of robotic arm. A mobile application was also developed that can control the robot arm using HC-05 Bluetooth technology through speech-based interfaces.
