File Information
Description

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 uses the file read command to read in an existing speech or audio file, the record function to record a new speech signal, and the file save command to save the results in a designated file on any desired MATLAB directory. The program plots the (existing or newly recorded) speech signal and its log energy contour. Finally, for newly recorded signals, the MATLAB program uses a graphical cursor to manually segment the recorded speech signal, as desired; e.g., to eliminate background signal both before and after the desired speech or audio signal, prior to saving the recorded speech or audio in the designated directory and in the designated file.
