Acoustic analysis is a proper method in vocal fold pathology diagnosis so that it can complement and in some cases replace the other invasive, based on direct vocal fold observation’s methods. There are different approaches for vocal fold pathology diagnosis. This paper presents a method based on hidden markov model which classifies speeches into two classes: the normal and the pathological. Tw...
