The three sections of the pharynx also assist with speech by amplifying the sounds produced in the vocal folds of the larynx. During speech, the larynx opens into the laryngopharynx; the oropharynx performs as the primary resonator for vocal sounds. Vowel pronunciation takes place here. The best resonator of the three sections, however, is the nasopharynx. It also connects with the middle ear through the eustachian tubes, which allows a direct connection between speech and hearing. Additionally, it is the sinuses working with these sections of the pharynx that add individual characteristics to a person’s voice.
