Speech processing designates a team consisting of Prof. Lawrence Rabiner (Rutgers University and University of California, Santa Barbara), Prof. Ronald Schafer (Stanford University), Kirty Vedula and Siva Yedithi (Rutgers University). This exercise is one of a set of speech processing exercises that are intended to supplement the teaching material in the textbook “Theory and Applications of Digital Speech Processing” by L R Rabiner and R W Schafer.
This MATLAB exercise illustrates the effect of using a periodic excitation for the glottal input signal (either periodic impulses or periodic glottal pulses) on the resulting log or linear magnitude spectrum of a set of frames of voiced speech of specified duration (pitch period).
