The cricothyroid muscle is the only tensor muscle of the larynx aiding with phonation. It is innervated by the superior laryngeal nerve. It is innervated by the superior laryngeal nerve. Its action tilts the thyroid forward to help tense the vocal cords , thus increasing the pitch of the voice.
The cricothyroid joint (or articulation) is a joint connecting the cricoid cartilage and the thyroid cartilage. It plays a key role in adjusting human voice pitch by changing the tension of the vocal cords .
In this, the muscle is an antagonist of the lateral cricoarytenoid muscle. [1] The muscle additionally draws the arytenoid cartilages posterior-ward, thus (assisting in) lengthening the vocal cords (here acting as synergist of the cricothyroid muscle). The lateral-most portion of the muscle also draws the arytenoid cartilages lateral-ward ...
The muscle closes the rima glottidis, adducting (approximating) the apices of the vocal process to close the ligamentous part of rima glottidis (in which it is synergystic with the oblique arytenoid muscles and transverse arytenoid muscle). [1] It thus functions to close the airway. [citation needed] It also shortens and slackens the vocal ...

The inferior pharyngeal constrictor muscle is a skeletal muscle of the neck. It is the thickest of the three outer pharyngeal muscles. It arises from the sides of the cricoid cartilage and the thyroid cartilage. It is supplied by the vagus nerve (CN X). It is active during swallowing, and partially during breathing and speech.

The vocal muscle is the upper portion of the thyroarytenoid muscle which is primarily involved in producing speech. A considerable number of the fibers of the thyroarytenoid muscle are prolonged into the aryepiglottic fold , where some of them become lost, while others are continued to the margin of the epiglottis.
