A vocal tremor occurs when one's voice shakes or quivers while speaking or holding a note. This trembling happens because the vocal cords vibrate irregularly, causing the voice to sound unstable. The tremor might change in speed or strength and can sometimes be seen along with other voice issues. It is important to note that vocal tremors can appear on their own or in association with different conditions, such as essential tremors or Parkinson's disease.

Doctors use special video techniques like stroboscopy or high-speed imaging to look at how your vocal cords move when you speak. These tools help capture the rapid changes and irregularities that cause the trembling. Treatment options depend on the underlying cause but may include voice therapy, medications, or Botox injections. These approaches aim to reduce the shaking so that you can speak more steadily, and the treatment choice is based on how severe the tremor is and what might be causing it.
