What Are the Main Types of Voice Disorders?

Voice disorders occur when the quality, pitch, or loudness of your voice is unusual or inappropriate for your age, gender, or background. According to the American Speech-Language-Hearing Association, a voice disorder is present when someone feels their voice is abnormal and it affects their daily life, even if others don’t notice a difference.

Voice disorders can make it difficult to speak clearly, often resulting from overusing your voice or problems with your voice box or vocal cords. While many people can improve with voice therapy, some may require medical or surgical treatment. These disorders can significantly impact communication and quality of life.

Main Categories of Voice Disorders

Voice disorders are divided into three main categories:

  1. Organic Voice Disorders: These are due to physiological changes in the respiratory, laryngeal, or vocal tract mechanisms.
    • Structural: Physical changes in the vocal mechanism, such as:
      • Changes in vocal fold tissues or abnormal growths on the larynx (e.g., vocal nodules or edema).
      • Age-related structural changes in the larynx, like thickening of the vocal folds.
    • Neurogenic: Problems with the nervous system affecting the vocal mechanism, such as:
      • Vocal tremor.
      • Spasmodic dysphonia (involuntary muscle spasms in the larynx).
      • Vocal fold paralysis.
  1. Functional Voice Disorders: These occur when the vocal mechanism is used inefficiently, despite normal physical structure.
    • Vocal fatigue.
    • Muscle tension dysphonia or aphonia (strained, breathy, or raspy voice).
    • Diplophonia (double pitch phonation due to vocal fold issues).
    • Ventricular phonation (compression of the false vocal folds over the true vocal folds, producing weak sounds).
  1. Psychogenic Voice Disorders: These are rare and occur when psychological stressors lead to habitual, maladaptive voice patterns.
    • Often linked to anxiety, depression, or conversion disorder.
    • May require referral to psychologists or psychiatrists for diagnosis and treatment.

Common Types of Voice Disorders

Some prevalent voice disorders include:

  • Hoarseness: A raspy or weak voice, caused by various factors such as infections or Parkinson’s disease.
  • Laryngitis: Swelling or irritation of the voice box, often due to allergies or infections.
  • Muscle Tension Dysphonia: Excessive stress on vocal cords leading to tight muscles.
  • Spasmodic Dysphonia: Muscle spasms in the voice box.
  • Vocal Cord Dysfunction (VCD): Vocal cords do not open fully, causing breathing problems.
  • Vocal Cord Lesions: Noncancerous growths like nodules, polyps, or cysts.
  • Vocal Cord Paralysis: Inability to control voice box muscles and vocal cords.

Risk Factors for Voice Disorders

While anyone can develop a voice disorder, certain factors increase the risk:

  • Age and Sex: Women over 50 are more susceptible.
  • Lifestyle: Smoking, drug addiction, and alcohol abuse can harm the lungs, larynx, and vocal cords.
  • Occupation: Professions requiring extensive speaking or voice use (e.g., teachers, singers, telemarketers and therapists).
  • Other Diseases: Conditions like Parkinson’s disease, multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), laryngeal cancer, laryngopharyngeal reflux (LPR) and gastroesophageal reflux disease (GERD).
