When producing sound, air flows from the lungs, causing the vocal cords to vibrate. The pitch and volume of the sound are controlled by muscles in the larynx, which contract and relax to adjust the tone of your voice. If the vocal cords are stretched tightly, the pitch will be higher; if they are relaxed, the pitch will be lower. Occasionally, interruptions in the airflow can cause vibrations in the vocal cords, resulting in a cracked voice. While puberty is a common cause of voice cracking, there are other factors that can lead to this phenomenon. Here are four additional causes of voice cracking beyond puberty.
Dehydration
One possible cause of a cracking voice during speech is dehydration. The vocal folds, which are membranous tissues, require proper hydration to function effectively. When you are dehydrated, your vocal folds may not operate as smoothly as they should, leading to unpredictable changes in your voice during speech. Dehydration can result not only from inadequate water intake but also from factors such as excessive sweating and consumption of caffeine and alcohol.
Vocal Cord Lesions
Extended periods of speaking, singing, or yelling can lead to irritation and potential damage to the vocal folds, resulting in the formation of lesions. These lesions, when healed, can cause stiffening of the vocal tissues, forming calloused patches known as nodules. Additionally, conditions like acid reflux, allergies, and sinus infections can contribute to the development of lesions on the vocal cords. Nodules can affect the flexibility and size of the vocal folds, potentially causing crackling sounds as the vocal folds struggle to produce regular sounds.
Laryngitis
Inflammation in the vocal folds, termed laryngitis, can notably affect the quality of one’s voice. While viral infections commonly trigger this inflammation, it can also arise from excessive voice use. When laryngitis is viral or due to vocal strain, it typically resolves within a short period. However, if caused by factors like air pollution or smoking, it may lead to more serious damage to the vocal folds and larynx, resulting in chronic laryngitis.
Strain And Tension
When you are worried, nervous, or tensed, you may have a tight voice that cracks. Tension in the muscles around the voice box is one cause of this. Another explanation is that when you are tense, you do not breathe properly, which can lead to pauses in your voice. This can also happen if your voice is tired, if you’re unwell, or if you’re agitated. When you sob, it is typical to have a squeaky voice because the muscles around the voice box are constricted and you are not breathing properly.
Conclusion
If your voice cracking is attributed to puberty, there’s typically no cause for concern. However, if it stems from underlying conditions, it’s crucial to address them promptly. Visiting your doctor for a proper diagnosis of the underlying cause is recommended. Meanwhile, you can take preventive measures such as staying hydrated, refraining from smoking and alcohol consumption, managing stress and anxiety levels, and practicing breathing exercises.
