Voice Disorder Detection And Classification- A Review

Abstract

The speech represents an intrinsic characteristic of human behaviour. Any disturbances in the normal speech of a human being are called speech disorder. It affects communication and social integration. Such patients will also have psychological and emotional issues as a direct result of their voice disorder. These day to day problems may cause a deterioration of the quality of life of an affected person and this results in the person trying to isolate himself from the activities of his daily life. Hence early detection of speech disorder is of utmost importance. Various conventional (invaasive) techniques for speech disorder detection were used earlier but extensive research has given rise to computer-based (non-invasive) methods of speech disorder detection. The computer-based techniques are easier to administer and are less expensive as compared to conventional methods. The important papers have been reviewed that describes the various voice disorder detection and classification algorithms from the recent years. The algorithms are divided based on the feature extraction techniques used for detection task. Various databases employed for evaluation of implemented approach are also explained. Deep learning techniques for speech pathology detection has great potential and recent studies are focussed on investigating deep learning architecture.
