Brian - if you know the path to the file that you want to read, then include that path along with the filename in the code to read the wav file. So you will want to "build" the path name given the data in your matrix. I don't know how your data is stored, but if one row of it is something like
data = {'12' 'CC' 'EAS'}
then you could do
filename = fullfile(pwd, data{2}, 'Processed Sentences', data{3}, [data{1} '.wav'])
which (on my desktop) initializes the filename variable as
filename =
'/Users/ghayes/Documents/MATLAB/CC/Processed Sentences/EAS/12.wav'
I'm assuming that the current directory in your MATLAB environment corresponds to the root of your wav file folder. If not, then you can replace the pwd with something else.
