Analysis of Time Domain Features of Dysarthria Speech

Abstract

In general, Speech can be described as the ability to express thoughts and feelings by articulating sounds in order to communicate with the person who understand the speech and accordingly interpret their action. The types of communication disorders that affects a person’s ability to produce speech sounds due to the lack of control over motor functions and articulators are speech disorders. Many people of varying age groups suffer from speech disorders and require early treatment in order to correct them. This paper analyses the time domain features such as jitter and shimmer that are extracted from the speech samples of dysarthria and healthy people. This is done by looking for dissimilarities between the different speech features preset in the normal healthy person and the disordered one by employing steps such as pre-processing followed by feature extraction.
