Vocal Hyperfunction and Its Causes
Describe and define deficits of vocal hyperfunction and research the medical conditions or environmental conditions that may lead to vocal hyperfunction. (Hints: think about kids yelling on the playground, a supervisor trying to talk over noise in a manufacturing plant to give employees instructions, and an anxious person attempting to explain their fears and worries.)
Vocal hyperfunction refers to the excessive or inefficient use of the vocal muscles during speech or singing. It often results in tension, strain, and improper phonation, leading to vocal fatigue, discomfort, and potential vocal damage (Roy et al., 2016). This condition is common among individuals who overuse or misuse their voice, especially in high-demand vocal environments.
Deficits of Vocal Hyperfunction
Individuals with vocal hyperfunction may experience:
- Hoarseness or rough vocal quality (indicative of strain).
- Increased vocal effort and fatigue (difficulty sustaining speech).
- Pitch breaks and voice loss (common in severe cases).
- Pain or tightness in the throat (due to excessive muscle tension).
- Reduced vocal range and control (especially in singers or public speakers).
Medical and Environmental Causes of Vocal Hyperfunction
1. Medical Conditions
- Muscle Tension Dysphonia (MTD): Excessive laryngeal tension leads to voice strain (Verdolini & Ramig, 2001).
- Vocal Cord Nodules/Polyps: Caused by chronic overuse, leading to vocal cord lesions (Titze, 2017)…
