Communication is an important part of daily life and can be a career necessity. Voice disorders — characterized by vocal fatigue, hoarseness, breathiness, talking too loud or soft — can be caused by anatomical disorders, functional disorders and by certain diseases.
Anatomical disorders can include nodules, polyps, cysts, paralysis or granulomas, which affect the vocal folds causing a change in the quality of the voice. Functional voice disorders are more often related to improper use of the vocal folds. Parkinson's disease and multiple sclerosis are just two of the many diseases that can cause changes in vocal quality.
Voice therapy can help increase stamina, increase or decrease range, decrease or eliminate hoarseness and affect volume. Vocal therapy helps a person learn about vocal hydration, vocal conservation, and how to recognize vocal warning signs of problems that could occur.
