Spasmodic dysphonia is a neurological disorder. It affects the larynx, also known as the voice box. The vocal cords spasm, affecting your voice and causing interruptions in speech.
Dysphonia: What You Need to Know
The causes of Dysphonia are unknown. While there is no way to completely prevent dysphonia, doctors recommend avoiding severe temperature changes as well as noisy environments that force you to strain your voice. In addition, keeping yourself hydrated and resting your voice (especially if your job requires you to talk a lot) can help.

What is dysphonia?
When we speak, air pushes its way between our vocal cords. The pressure on the vocal cords causes them to vibrate, which produces our voice. In patients with spasmodic dysphonia, the vocal cords spasm, meaning they suddenly move. This spasm interferes with the vocal cords' ability to vibrate and produce voice. Dysphonia can cause the voice to sound strange and can interfere with your ability to talk and communicate.
There are three types of spasmodic dysphonia:
Adductor spasmodic dysphonia, the most common type, occurs when the vocal cords stiffen, causing the voice to sound strained.
Abductor spasmodic dysphonia occurs when the vocal cords open, making the voice sound weak.
Mixed spasmodic dysphonia is a combination of adductor and abductor and is very rare.
We don't know what causes dysphonia. Doctors think it is due to abnormal functioning in part of the brain. The symptoms can appear slowly over time. In some cases, spasmodic dysphonia can run in families.
Doctors have not identified specific risk factors for dysphonia. However, research has shown that the symptoms sometimes begin following:
Upper respiratory infection
Injury to the larynx (voice box)
Overusing or overstressing your voice
