Grunts (family Haemulidae) are so called because of the sound they make when they grind them. [2] Molas are said to be able to produce sound by grinding their long, claw-like pharyngeal teeth. The Chinese high fin banded shark ( Myxocyprinus asiaticus ) (family Catostomidae ) has a single row of pharyngeal teeth with comb-like arrangements. [ 3 ]
In essence, sound is generated in the larynx by chopping up a steady flow of air into little puffs of sound waves. [30] The perceived pitch of a person's voice is determined by a number of different factors, most importantly the fundamental frequency of the sound generated by the larynx. The fundamental frequency is influenced by the length ...
The word guttural literally means 'of the throat' (from Latin guttur, meaning throat), and was first used by phoneticians to describe the Hebrew glottal (א) and (ה), uvular (ח), and pharyngeal (ע). [4] The term is commonly used non-technically by English speakers to refer to sounds that subjectively appear harsh or grating.
The vocal tract is the cavity in human bodies and in animals where the sound produced at the sound source (larynx in mammals; syrinx in birds) is filtered.. In birds, it consists of the trachea, the syrinx, the oral cavity, the upper part of the esophagus, and the beak.
While primary aspects of the voice are produced in the throat, the tongue, lips, and jaw are also needed to produce the range of sounds included in speech. The mouth consists of two regions, the vestibule and the oral cavity proper. The mouth, normally moist, is lined with a mucous membrane, and contains the teeth.

The laryngopharynx, (Latin: pars laryngea pharyngis), also known as hypopharynx, is the caudal part of the pharynx; it is the part of the throat that connects to the esophagus. It lies inferior to the epiglottis and extends to the location where this common pathway diverges into the respiratory ( laryngeal ) and digestive ( esophageal ) pathways.
