This article provides an in-depth and original analysis of the work of the organs of speech, examining how various anatomical structures cooperate to produce human language. It discusses the roles of the respiratory, phonatory, articulatory, and resonating organs, highlighting how airflow, vocal fold vibration, and articulatory movements interact to generate speech sounds. The study explains the functions of major speech organs such as the lungs, diaphragm, larynx, tongue, lips, palate, and nasal cavity, emphasizing their coordinated activity in respiration, phonation, articulation, and resonance. Through descriptive and analytical approaches, the article demonstrates that spoken language is the result of a highly complex physiological system that transforms airflow into meaningful sounds. Understanding the work of the organs of speech is crucial for linguistics, phonetics, speech therapy, and language teaching, as it provides the foundation for analyzing pronunciation, correcting articulation, and treating speech disorders.
