The Role of Stress, Intonation, And Rhythm in Language Systems
Abstract
This paper examines the role of stress, intonation, and rhythm in language systems, focusing on their structural, cognitive, and communicative functions. Stress contributes to lexical differentiation and information highlighting, intonation conveys grammatical, pragmatic, and emotional meaning, and rhythm provides temporal organization that enhances speech intelligibility. A combination of acoustic analysis, cross-linguistic comparison, and qualitative assessment was employed to investigate these suprasegmental features. The findings demonstrate that stress, intonation, and rhythm operate synergistically, facilitating comprehension, emphasizing meaning, and conveying social and emotional cues. Understanding these prosodic elements is essential for linguistics, second language acquisition, and applied fields such as speech therapy and speech technology.
