A MATLAB exercise that uses the file read command to read in an existing speech file, the
record function to record a 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., eliminate background signal both before and after the desired speech signal, prior to saving the recorded speech in the designated directory and in the designated file. The file '1.5 Speech Record and Display.pdf' provides a User's Guide for this exercise.
