To perform speech recognition is used CSLU TOOLKIT with a corpus of Mexican Spanish voice, recognized commands are sent via Bluetooth from computer to robot, programming and motion routines to control the motors are done using Java and LeJOS NXJ. The interface consists of two main modules interconnected through the implementation of sockets: the voice recognition module and the wireless control module. The results indicate that the wireless control system of the LEGO NXT robotthrough voice commands successfully meets its objective.
