function cleaning_directory_filename()

I think the function cleaning_directory_filename() breaks the speaker independence in the paper, i.e., 10-fold cross-validation, causing speaker overlap in the training and test sets. Removing this function, I get an 8% drop in WA. Could you explain my confusion.

I have the same the question, do you verify it?
