Voice (Vocal) Tremor

Vocal tremor is caused by trembling or shaking vocal cords. Most vocal tremor may be a component of neurologic essential tremor, though other neurologic disease can also cause tremor.

Generally seen in an aging population, voice tremor causes the voice to take on a wavering, unsteady quality.

Diagnosing Vocal Tremor

Vocal tremor diagnosis can typically be made by patient history and listening carefully to the patient’s voice. Tremor can often also be seen on physical exam. Vocal tremor may sometimes overlap with spasmodic dysphonia.

Vocal Tremor Treatment

Patients with vocal tremor may elect to have botulinum toxin injections, which lessen the amount of tremor as they weaken the vocal cord muscles. Because botulinum toxin may lead to a quiet voice as it reduces tremor, some patients prefer not to have injections. An alternative treatment is voice therapy, which can help patients to speak more strongly and more clearly.
