DEVELOPMENT OF BREATHING AND VOICE DISORDERS IN CHILDREN WITH DYSARTHRIA

Abstract

Dysarthria is a neurological motor speech disorder characterized by impairments in the muscles responsible for speech production. Among the most significant manifestations of dysarthria are breathing and voice disorders, which directly affect speech intelligibility, communication effectiveness, and social participation. Respiratory and phonatory impairments frequently occur due to inadequate neuromuscular control, reduced muscle strength, abnormal muscle tone, and impaired coordination of speech-related structures. These difficulties often limit a child's ability to produce adequate breath support, maintain vocal intensity, and regulate speech rhythm. The purpose of this study is to examine the development of breathing and voice disorders in children with dysarthria and to analyze their impact on communication abilities. The study reviews theoretical perspectives, neurological mechanisms, clinical characteristics, assessment procedures, and intervention approaches related to respiratory and phonatory dysfunctions. Findings indicate that respiratory and voice impairments significantly contribute to communication difficulties and may negatively affect academic achievement, social interaction, and overall quality of life. Early identification and comprehensive intervention targeting respiratory control and voice production can improve communicative outcomes and enhance functional participation
