Speech Recognition and Control of Robotic Cars Using MATLAB

This graduation project from An-Najah National University's Mechanical Engineering Department delves into speech recognition technology and its application in controlling robotic cars. Supervised by Dr. Bashir Nouri and prepared by Jafar M.S. Qamhyeh, Karem M. Masri, Khaled F. Bani Fadel, and Mohammed M. Abu-Issa, the project explores microphone types, how they work, sound card signal recording, and advanced signal processing techniques such as FFT and filtering methods. Utilizing MATLAB software, the project demonstrates effective speech signal processing and its implementation in robotic control systems.
