Glottal refers to the sound produced by the vibration of the vocal cords, which occurs in the region of the glottis in the throat. Other synonyms for glottal include laryngeal, pharyngeal, and uvular. Laryngeal refers to the area of the larynx, where the vocal cords are located. Pharyngeal relates to the pharynx, which is the portion of the throat behind the mouth and nasal cavity. Uvular refers to the uvula, which is the small, fleshy structure that hangs down from the soft palate in the back of the mouth. All of these terms describe the same process of creating sound from the vocal cords and resonate differently depending on their location in the throat.
