dysphonia
Let an agent explain dysphonia and its causes, relay assessment and general management from ENT and speech-language pathology sources, describe the forms the registry aliases name, and distinguish dysphonia from aphonia, dysarthria, spasmodic dysphonia as a specific disorder and normal voice change, routing persistent hoarseness to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain dysphonia and its causes, relay assessment and general management from ENT and speech-language pathology sources, describe the forms the registry aliases name, and distinguish dysphonia from aphonia, dysarthria, spasmodic dysphonia as a specific disorder and normal voice change, routing persistent hoarseness to clinicians.
An impairment of voice production affecting pitch, loudness, quality or effort, commonly experienced as hoarseness, with forms including muscle tension dysphonia from inefficient use of laryngeal muscles, childhood dysphonia often from vocal nodules, and a toneless or breathy voice, and causes ranging from laryngitis and voice overuse to vocal fold lesions, nerve paralysis and laryngeal cancer. Hoarseness lasting more than a few weeks, especially in smokers, needs medical assessment. The model routes people to clinicians.
What it is for: Not applicable; a voice disorder.
It can be explain forms and causes; relay assessment and therapy; route to clinicians; distinguish related disorders.
Distinguishing features
Voice quality change
Functional or organic
Common
Voice therapy
What it looks like
Not a visible object; a hoarse, strained or breathy voice.
Physical character
lifetime prevalence of voice disorders: about 30 percent - adults, estimates
referral guidance: hoarseness over about 3-4 weeks note - guidelines vary
assessment: laryngoscopy note
How it is recognised
Impaired voice production
Hoarseness, childhood dysphonia, toneless voice, muscle tension dysphonia
Aphonia is loss of voice; dysarthria is articulation; spasmodic dysphonia is a focal dystonia; puberty voice change is normal
