Diagram Of The Vocal Mechanism. Focal mechanisms have been used to evaluate a specific mechanism by which dehydration embrittlement could generate large intermediate to deep earthquakes. Each vocal fold is about 1115 mm long in adult women and 1721 mm in men and stretches across the larynx along the anterior posterior direction attaching anteriorly to the thyroid cartilage and posteriorly to the anterolateral surface of the arytenoid cartilages fig.
The vocal cords are protected by the adams apple or thyroid cartilage and are located midway in the throat. B superior view of larynx when the vocal folds are adducted as during phonation. It begins at the velum and terminates at the nostrils.

The air then comes up from the lungs via the vocal tract and exiting as a sound wave. Vocal mechanism and result in a strident pressed or pushed sound. The heavy mecanism is used mainly by men it can produce sounds between 80 hz and 400 hz. Human speech is a combination of sounds and silences generated by the speech mechanism of the vocal tract into meaningful patterns.
