Abstract/Summary

Speech recognition systems have been developed in the past. Various technologies have been used including Field Programmable Gate Array (FPGA). With this research, it is the authors’ main objective to develop in a single FPGA a servo motor controller that is activated using speech commands, namely, stop, clockwise and counterclockwise. The software model that was used as a blueprint in the FPGA implementation was done in MATLAB. Besides being the basis for the FPGA design, the MATLAB model was also used for getting the various speech parameters that were then inputted to the FPGA for speech recognition. FPGA implementation was then made using hardware description language (HDL) in 2 major parts: 1) speech recognition system including the speech acquisition module and 2) servo motor controller pulse width modulation (PWM) system. Afterwards, the system was tested for recognition accuracy using an acoustics laboratory with sound-proofing materials to minimize noise. With 200 samples each word, the commands stop, clockwise and counterclockwise had 100.00%, 98.00% and 100.00% accuracy respectively versus the research minimum objective of 70% per command.
