Pronunciation: [fˈɒls vˈə͡ʊkə͡l kˈɔːdz] (IPA) 
The spelling of "false vocal cords" can be confusing due to the silent "e" in "false" and the pronunciation of "vocal" with a long "o" sound instead of a short "o." Additionally, the "c" in "cords" is pronounced as a "k," and the "ds" is pronounced as a "z." In IPA phonetic transcription, the word is spelled /fɒls ˈvəʊk(ə)l kɔːdz/, which breaks down the pronunciation of each individual sound in the word.
The false vocal cords, also known as ventricular vocal cords or vestibular folds, refer to a pair of thick, muscular folds located superiorly to the true vocal cords in the larynx. These structures play a pivotal role in speech production and protection of the airway.
Functionally, the false vocal cords contribute to the production of sound during vocalization. They assist in creating a clear, resonant tone and are responsible for adding depth and richness to one's voice. However, their primary role lies in protecting the true vocal cords and the lower respiratory tract. When swallowing, the false vocal cords close tightly, preventing food or liquids from entering the lungs. They act as a safeguard against foreign particles, preventing potential hazards from reaching the delicate structures of the larynx, trachea, and lungs.
Despite their name, the false vocal cords do not participate in phonation, unlike the true vocal cords. Instead, they share a close anatomical relationship with the true vocal cords and collaborate in vocalization and the production of certain sounds. Together, they control the airflow and create oscillations that generate speech, allowing for the creation of a wide range of sounds and pitches.
In summary, the false vocal cords are muscular folds located above the true vocal cords in the larynx, contributing to voice production, protection of the airway, and maintaining respiratory health.
