Spasms and tremors, or spasmodic dysphonia, can compromise your voice and make it difficult to communicate. The folds of muscle within the larynx may ripple involuntarily, preventing the vocal cords from vibrating properly and thus inhibiting sound.
How Vocal Tremors and Spasms Work
Speaking occurs when air from the lungs vibrates the vocal cords, producing a sound. When the vocal muscles move involuntarily, it is called spasmodic dysphonia. This ailment can prevent the cords from vibrating sufficiently to make normal sounds.
Vocal tremors and spasms can create interruptions in the flow of speech, making it challenging to hold a conversation. The rate and frequency of vocal spasms will vary from person to person. If your vocal tremors are making it difficult to be understood, it may be time to consider medical intervention.
