What is sub glottal?

Subglottal refers to the area or space located below the vocal cords (glottis) in the larynx. It is significant in the study of phonetics and voice production, as it plays a crucial role in controlling airflow and pressure during speech and singing. Proper subglottal pressure is essential for producing sound and maintaining vocal quality. Issues in this area can lead to voice disorders and affect one's ability to speak or sing effectively.
