Definition

Loss of voice (also called aphonia) may take several different forms. You may have a partial loss of your voice (such as mild hoarseness). Or, you may have complete loss of your voice. (For example, your voice sounds like a whisper.) Loss of voice can come on gradually or rapidly depending on the cause. It is usually due to problems with the voice box (called the larynx). However, there can be other causes.

Aphonia is different than aphasia, which is a communication disorder.

Causes

Aphonia can be caused by:

Risk Factors

These factors increase your chance of developing aphonia:

  • Overusing voice (eg, speaking until you are hoarse)
  • Engaging in behaviors that abuse your vocal chords, such as smoking, which also puts you at a higher risk for cancer of the larynx
  • Having surgery on or around the larynx

Symptoms

Symptoms may include:

  • Inability to speak or inability to speak above a whisper
  • Hoarseness
  • Spasm of vocal cords
  • Throat pain
  • Difficulty swallowing (Food or fluids may go into the lungs.)

When Should I Call My Doctor?

Call your doctor if you:

  • Have hoarseness that is not getting better after about two weeks
  • Have complete loss of voice lasting more than a few days
  • Have hard, swollen lymph nodes
  • Have difficulty swallowing
  • Cough up blood
  • Feel of a lump in your throat
  • Have severe throat pain
  • Have unexplained weight loss
  • Have any other concerns

When Should I Call for Medical Help Right Away?

Call for medical help right away or go to the emergency room if you:

  • Suddenly lose your ability to speak—This may be a sign of a head injury or a stroke.
  • Are having trouble breathing
.

If you think you have an emergency, call for medical help right away.

Diagnosis

Your doctor will ask about your symptoms and medical history. She will also do a physical exam.

If the underlying cause of your hoarseness is not obvious, you may be referred to a ear, nose, and throat doctor. This doctor may use an instrument called a laryngoscope to examine your vocal cords. They may do other tests to also evaluate your voice function.

If your doctor is concerned that there may be an underlying neurological or psychological concern, you may be referred to other specialists.

Treatment

General measures that can help for laryngitis include:

  • Resting your voice
  • Avoiding smoking
  • Staying hydrated
  • Using a cool mist humidifier
  • Taking nonprescription pain relievers (eg, acetaminophen, ibuprofen) as needed

Other treatments depend on the specific cause, such as:

  • Participating in voice therapy if your loss of voice is due to voice overuse
  • Taking medicine to control acid reflux
  • Having surgery to remove growths

Prevention

To help reduce your chance of getting aphonia, take the following steps:

  • If you smoke, quit.
  • If you drink, do so in moderation.
  • Limit your exposure to fumes and toxins.
  • Avoid talking excessively or yelling.
  • Avoid whispering
  • If you have to speak a lot for your job, learn proper vocal techniques from a voice therapist.
  • Get treatment for underlying conditions that may cause loss of voice.
