Isolated Word Command Recognition for Robot Navigation

AbstractThis project is demonstrating Robot Navigation Control using Isolated Word Recognition. Five spoken word commands (Go, Stop, Left, Right and Back) should be record and used as commands. Fast Fourier Transform (FFT) is used to filter the noise by creating butter worth filter. The noise cancelation method is then used to make the software sensitive and recognize the word Normalization, Power density spectrum and voice fingerprint method are used and implemented by MATLAB programming code. Then the command signal of recognized word is sent via XBee, wireless connection to robot. The robot will receive and response to the spoken command signal by a PIC microcontroller which will control the robot movement
