laryngeal cavity

The rima vestibuli is a space in the laryngeal cavity.

In mammals it consists of the laryngeal cavity, the pharynx, the oral cavity, and the nasal cavity.

The laryngeal cavity (cavity of the larynx) extends from the laryngeal entrance downwards to the lower border of the cricoid cartilage where it is continuous with that of the trachea.

Harsh voice, also called ventricular voice or (in some high-tone registers) pressed voice, is the production of speech sounds (typically vowels) with a constricted laryngeal cavity, which generally involves epiglottal co-articulation.
