What is the connection between speech and vocal cord? Both the vocal tract as well as the vocal cord has a major role to play in the production of speech. Several organs are present inside the vocal tract that regularly monitor and control the centers of speech. For this they take the help of brainâs internal feedback.
It is formed by nine cartilages (see cartilages of the larynx): These cartilages are connected to each other by muscles and ligaments and lined with mucous membrane. Movement of the cartilages alters the tension of the vocal folds, which changes the pitch of the sound emitted by the vocal folds when they vibrate. The larynx is the upper, expanded portion of the trachea which is specially modified for the production of the voice.
