Protect your larynx and voice

Throughout the course of a day, you may speak, laugh, hum, whistle, and even sing or shout. But how much do really think about your voice?

April 16 is World Voice Day, and voice professionals around the world are encouraging men and women to take charge of their vocal health through education.

Understanding the functions of the larynx, which plays the biggest role in our vocal health, is the first step to understanding the importance of your voice.

Felicia Carter, speech-language pathologist in otolaryngology at Baylor College of Medicine, offers some important facts about the larynx and your voice.

The larynx and its functions

The larynx, or voice box, has three important functions: manage airflow during breathing and coughing, protect the airway when swallowing and produce speech and sound.

“The larynx is a part of the respiratory tract that contains the vocal folds to produce sound and protect your airway during swallowing,” said Carter. “Voicing requires the balance of three subsystems: respiration (power through breath), phonation (vibration of vocal folds) and resonance (amplification through space of the throat, mouth and nose).”

More than 100 muscles are used when speaking or singing. Some of the same muscles used for speaking and singing are also used for swallowing.

Signs and symptoms

Even with good training, voice issues may still arise.

“Voice problems can occur if other health or medical conditions are not addressed, such as smoking and cancer,” said Carter.

Signs that may indicate vocal health issues include:

  • Persistent hoarseness for more than two weeks
  • Breathy voice
  • Straining to speak
  • Decreased singing range

Preventative measures

It is never too late to take action on your vocal health.

To help protect the larynx, Carter says to avoid smoking, shouting and talking over loud voices, screaming and excessive throat clearing. She also suggests limiting your speech during a cold or laryngitis and most importantly, staying hydrated.
