Narrowband/Wideband Spectra of a Speech Frame

Compares and contrasts the effects of using either of two different windows

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 compares and contrasts the effects of using either of two different windows (Hamming and rectangular), with two different frame durations (Narrowband–NB and Wideband–WB), on the computation of the short-time Fourier transform (STFT) of a user-selected frame of speech.
