Spasmodic Dysphonia

Spasmodic dysphonia is a neurological voice disorder characterized by involuntary spasms of the laryngeal muscles during speech, causing interruptions in voice production. The most common form, adductor spasmodic dysphonia, causes the vocal folds to close too tightly, producing a strained, strangled voice quality with breaks in phonation. For digital accessibility, individuals with spasmodic dysphonia may have inconsistent success with voice recognition systems due to the variable nature of their speech. AAC devices and text-based communication alternatives may be helpful during severe episodes.
