![]() ASHA gives the example of a client who has trauma to their vocal chords, which then leads to structural, or organic, changes to the tissue in the chords. A psychogenic voice disorder, also known as psychogenic conversion aphonia/dysphonia, is a rare disorder in which psychological stressors affect the voice quality. Voice disorders may result from one or both of these. An example of a functional voice disorder includes vocal fatirue or ventricular phonation A structural example includes edema or vocal nodules, and a neurogenic example includes a vocal tremor, paralysis of cords, or spasmodic dysphonia. An organic voice disorder “results from alterations in respiratory, laryngeal, or vocal tract mechanisms.” A functional voice disorder reults from “improper or inefficient use of the vocal mechanism when the physical structure is normal.” Organic is broken up into structural or neurogenic. According to ASHA, a voice disorder is when a client’s “voice quality, pitch, and loudness differ or are inappropriate for an individual’s age, gender, cultural background, or geographic location.” An interesting point to note for a future speech-language pathologist to remember is that a client can have a voice disorder even if it doesn’t seem to be different from normal if they believe that it does not meet their daily needs.Ī voice disorder is categorized as either organic or functional. ![]()
