This project aims at developing a robot on a field programmable gate array, which can perform tasks by taking the user’s voice commands. The robot has two wheels for locomotion and IR sensors. It can also autonomously direct itself according to the obstacles coming in its path with the help of IR sensors. The objective is to make the robot to recognize a limited set of commands for giving directions (typically 4), and move accordingly. Mel-frequency cepstral coefficients are used as the features that represent the input voice-commands and dynamic time warping algorithm is implemented for the recognition of the commands. The entire voice-command recognition module has both hardware and software components. The software runs on MicroBlaze, a 32-bit soft-core processor from Xilinx. A hardware-software co-design of a voice-command feature extraction circuit is implemented and validated on Spartan-6 FPGA. It is also compared against a complete softwarebased implementation and a complete hardware-based design.
