Spasmodic dysphonia, also known as laryngeal dystonia, is a disorder in which the muscles that generate a person's voice go into periods of spasm. [1] [2] This results in breaks or interruptions in the voice, often every few sentences, which can make a person difficult to understand. [1]

Abductor spasmodic dysphonia is another type of condition, which causes “sudden involuntary spasms that trigger the vocal cords to open,” per John Hopkins Medicine.
Voice disorders can be divided into two broad categories: organic and functional. [9] The distinction between these broad classes stems from their cause, whereby organic dysphonia results from some sort of physiological change in one of the subsystems of speech (for voice, usually respiration, laryngeal anatomy, and/or other parts of the vocal tract are affected).
What causes spasmodic dysphonia? The disorder is a neurological problem, the Cleveland Clinic says, that is believed to start in the basal ganglia—a part of the brain that coordinates muscle ...
Spasmodic dysphonia affects up to 50,000 people in North America, and is a subset of dystonia, a muscle contraction disorder that can affect many parts of the body. In one type of vocal dystonia ...
Multiple factors cause the muscles of the larynx to become tense. This changes the position of the larynx and affects the cartilaginous structures within the larynx leading to abnormal phonation. [3] There is increased muscle activity in MTD due to personal temperament, increased vocal use, and underlying medical or physical causes. [3]
Voice disorders [1] are medical conditions involving abnormal pitch, loudness or quality of the sound produced by the larynx and thereby affecting speech production. These include:
