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]
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:
Causes distortions of the mouth and tongue. Spasmodic dysphonia/Laryngeal dystonia muscles of larynx: Causes the voice to sound broken, become hoarse, sometimes reducing it to a whisper. Focal hand dystonia (also known as musician's or writer's cramp). single muscle or small group of muscles in the hand

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]
