Acquired Voice Disorders
Understanding Voice Disorders
A Voice Disorder affects the quality, pitch, or loudness of your voice. A Speech-Language Pathologist (SLP) specializes in evaluating and treating these acquired conditions in adults.
Causes
Voice disorders occur when there is a problem with the vocal folds (vocal cords) or the way air is controlled for speaking. Common causes include:
Vocal Abuse/Misuse: Excessive yelling, singing without proper technique, or chronic coughing.
Lesions: Growths on the vocal folds such as vocal fold nodules and polyps or cysts.
Neurological Conditions: Conditions like Parkinson's disease or damage from a stroke that affect nerve control of the larynx.
Vocal Fold Paralysis: Damage to the nerves that move one or both vocal folds, often due to surgery or infection.
Laryngeal Issues: Conditions like Spasmodic Dysphonia (involuntary vocal fold movements) or Paradoxical Vocal Fold Movement (PVFM) (vocal folds closing when they should open for breathing).
Reflux: Laryngopharyngeal reflux (LPR) or GERD can irritate the vocal folds.
Signs and Symptoms
If you have a voice disorder, you may experience one or more of the following:
Hoarseness/Roughness: A scratchy, raspy, or harsh voice quality.
Breathiness: Voice sounds airy because air is leaking past the vocal folds.
Loss of Pitch: Difficulty hitting high notes or a voice that is consistently too high or too low.
Reduced Loudness: Inability to speak loudly or a sudden change in volume.
Voice Loss: Periods where you "lose" your voice completely.
Pain or Strain: Feeling tension, soreness, or fatigue in the throat when speaking.
SLP Evaluation and Treatment
An SLP works closely with an ear, nose, and throat doctor (ENT/laryngologist) to diagnose and treat voice disorders.
1. Evaluation Techniques
Case History: Discussing your vocal demands, lifestyle, and medical history.
Auditory-Perceptual Assessment: The SLP listens to and describes the acoustic qualities of your voice (e.g., degree of hoarseness, breathiness).
Acoustic Analysis: Using specialized equipment to measure pitch, loudness, and quality.
Laryngeal Imaging Review: Reviewing images (often provided by the ENT) of your vocal folds to see movement and identify lesions.
2. Treatment Techniques
Treatment focuses on restoring the vocal folds to healthy, efficient function, primarily through Voice Therapy:
Vocal Hygiene Education: Teaching how to reduce vocal abuse (e.g., proper hydration, avoiding excessive throat clearing).
Voice Exercises: Using techniques like LSVT LOUD, SPEAK OUT! for Parkinson's Disease
Resonance Voice Therapy to improve vocal power, clarity, and efficiency.
Breathing Techniques: Training proper breath support for sustained speech.
Relaxation: Reducing muscle tension in the head and neck that can strain the voice.
