Recognition and Classification Of Speech And Its Related Fluency Disorders

Speech is an integral part of communication. Speech disorder is a problem with fluency, voice, and or how a person produces a speech sound. The main focus of this study is to identify the difference between normal and disordered speech. The proposed work classifies the normal and abnormal speech. The experimental investigation elucidated MFCC and DTW with the accuracy rate of 88 % and 75% respectively. The K-means classifier is used to distinguish the speech disorder with classification rate of 93% on basis of energy entropy and pitch values of the subject. The obtained results are justified using t-test. Keywords— MFCC, Fluency disorder, DTW, KNN and feature classification.
