A device used to observe and record the intralaryngeal phenomenon of phonation (speech). It is comprised of a number of components, e.g., a rhino-laryngeal stroboscope unit, camera, video recorder, computer and software, and will typically be used together with an appropriate endoscope. It is typically used in ear/nose/throat (ENT) departments to investigate the correct functioning of the vocal apparatus (glottis) and to investigate voice disorders.
