Created using ChatSlide

This lecture introduces the anatomy and physiology of speech, emphasizing how airflow becomes meaningful language. Postgraduates will define speech, voice, and language; examine the respiratory, phonatory, and resonatory systems; and trace the roles of key structures. It explains respiration as the power source, highlighting the lungs, diaphragm, and intercostal muscles, then explores the larynx as the sound generator, including its C3–C6 location, nine cartilages, and true vocal folds.
