Abstract

Voice pathology is interrelated to a vocal folds complication, and the vocal tract area which is attached to vocal folds shows a variable shapes in case of voice pathology. This variable shapes are tested to make the division of healthy and pathological voices. So, Length and area of vocal tract are used for finding electrical parameters using transmission line theory by considering the vocal tract as a sequence of tubes. The proposed work is used voice database from the Saarbrucken Voice Database (SVD) and real-time data from the Maharishi Markandeshwar (M.M) hospital, Mullana. The proposed method achieves a higher accuracy of 91.7 percent with electrical parameters compared to 88.2 percent with the acoustic parameters and 85.3 percent with physical parameters in the detection of voice pathology.
