Read_Me: Instructions for setting up matlab speech processing exercises. Step 1: create directory for loading all necessary file folders from MATLAB speech processing exercises (e.g., we create the directory �matlab_central_speech�); we define the full path to the chosen directory), e.g., path-to-speech= 'C:\data\matlab_central_speech' Step 2: follow the instructions from the Read_Me file which is included within the folder for each of the speech processing exercises) Step 3: do the following: download (from Matlab Central File Exchange) and extract the following code folders and data folders into the directory of Step 1, using the following: -go to Matlab Central -click on File Exchange -type speech processing exercises in the search region - extract to the directory of Step 1 the following folders: - functions_lrr - speech_files - highpass_filter_signal - VQ - cepstral coefficients - isolated_digit_files - GUI Lite v2.6 (soon to be available) Step 4: download (from Matlab Central File Exchange) any or all of the folders for the set of speech processing exercises: -go to Matlab Central -click on File Exchange -type speech processing exercises in search menu -find any or all of the current set of 58 speech processing exercises and download them (one-at-a-time) to the directory of Step 1 Step 5: edit the file 'pathnew_matlab_central' -change the path-to-speech directory name to the one selected in Step 1 -run the resulting pathnew_matlab_central file (this file must be run each time you log into Matlab) The resulting 'pathnew_matlab_central' should look like the following (for a starting directory of �C:\data\matlab_central_speech'): ************************************************************************ % pathnew_matlab_central % % path-to-speech: starting directory definition path-to-speech='C:\data\matlab_central_speech' % paths to GUI toolkit path(strcat(path-to-speech,'\gui_lite_2.6\GUI Lite v2.6'),path); % paths to speech toolkit path(strcat(path-to-speech,'\functions_lrr'),path); path(strcat(path-to-speech,'\speech_files'),path); % path to highpass filter mat files path(strcat(path-to-speech,'\highpass_filter_signal'),path); % path to cepstral coefficient training files path(strcat(path-to-speech,'\VQ'),path); % path to cepstral coefficients path(strcat(path-to-speech,'\cepstral coefficients'),path); % path to lrr isolated digit files set for training and testing path(strcat(path-to-speech,'\isolated_digit_files\testing set'),path); path(strcat(path-to-speech,'\isolated_digit_files\training set'),path);
