If you haven’t had any water or other liquids in a while, the vocal folds can’t move as smoothly and may irregularly change size or shape as you speak or sing. This one’s pretty straightforward: Your vocal folds need to be moist in order to move properly. This can lead to squeaks and cracks as your vocal folds have difficulty producing normal sounds. Nodules can affect your vocal fold flexibility and size. Lesions can also be caused by acid reflux, allergies, or sinus infections. Speaking, singing, or screaming for long periods of time can irritate your vocal folds and even damage this tissue, resulting in injuries known as lesions.Īs these lesions heal, the vocal tissues harden, leaving calloused areas known as nodules.

This makes your voice crack as the CT muscle moves quickly trying to transition between high and low pitch or volume.
With the CT muscle in particular, if you try to aggressively increase or decrease your pitch, or even raise or lower your volume without doing some vocal exercises, the laryngeal muscles can tighten, loosen, expand, or shrink too quickly. If you use it too abruptly or without warming it up, the muscle can tighten and become hard to move. As with any other muscle, the CT muscle is best used slowly, carefully, and with training. The pitch of your voice results from the movement of the cricothyroid (CT) muscle.
This makes the muscles more likely to suddenly tighten or lose control, resulting in a crack or squeak, as you learn to get used to the new anatomical arrangement in your throat. This sudden change in size, shape, and thickness can destabilize your vocal cord movements when you speak.
