How to Take Care of Your Voice?


Call Center agents, along with teachers or educators are considered professional voice users.  They are people with vocally demanding occupations, thus, making them more susceptible to developing voice disorders.  This simple guide aims to empower these professionals to practice proper vocal health management in order to promote and maintain good vocal health.

How is Voice Produced?

Air from the lungs comes up and passes through the vocal cords.  The vocal cords produce a buzz-like sound when air gets them to vibrate.

This sound is modified into a resonant tone as it passes up through the mouth, throat and nose, and is further modified by the position of the palate, tongue, and lips.

Most common mistake of voice professionals

  • Voice Abuse– Talking in a noisy environment for more than 1 hr; Talking for a prolonged period of time in a high volume voice, shouting or yelling
  • Voice Misuse– talking in a pitch beyond the optimum; talking without breath support.


Common Vocal Complaints of Voice Professionals

  1. VOCAL FATIGUE symptoms:
  2. dry mouth
  3. a need to clear your throat
  4. hoarseness
  5. “scratchy” or raw feeling in your throat
  6. achy feeling in your neck
  7. low pitched voice
  8. a general feeling of weakness when speaking
  9. frequent breaths or running out of breath
  10. reduced volume on high or low pitches
  11. tension in the neck, shoulders and upper chest



Change in voice quality characterized by either breathiness or roughness of voice, may or may not be associated with asthenia and strain when speaking.


Usually gets you into the habit of clearing your throat; also changes vocal quality to hyponasal in nature thus making talking more difficult.

  1. Maintain vitality of vocal cord mucosa
  2. Hydration is the most important key to maintain vitality of vocal cords


Systemic Hydration

Definition: the internal hydration of the entire body that keeps the skin, eyes and all other mucosal tissue healthy

  • Drink 8-10 glasses of water per day
  • Avoid the following items that cause dehydration:

Caffeine, alcohol, large doses of vitamin C, Diuretic drugs, antihistamines, cigarette smoking, and marijuana

Topical (surface) Hydration

Definition: the moisture level that keeps the epithelial surface of the vocal folds slippery enough to vibrate

  1. Maintain a nice vibratory environment for the vocal cords
  • Medical intervention for Laryngopharyngeal reflux
  • Manage sinus problems
  • Control allergies


  1. Avoid trauma to the mucosa by avoiding…
  • Throat clearing
  • Coughing
  • Screaming/yelling
  • Hard glottal attack
  • Grunting
  • Extensive loud talking
  • Extensive talking at inappropriate pitch or excessive loudness
  • Extensive talking in glottal fry


  1. Treat the muscle of the vocal cord mechanism like an athlete


Muscle concepts

  • Vocal muscles need to be warmed up before extensive use
  • Muscles need to be trained carefully and gradually
  • Fatigued muscles need rest and gradual return to activity
  • Cool-down can be important for many vocal athletes
  • Mucosa must be kept healthy and lubricated
  • Once swelling has occurred, impact to the mucosa must be reduced by going on voice rest


  1. Use Vocal cord mechanism wisely.
  • Voice conservation should be practiced
  • Avoid unnecessary talking, gossiping, and marathon videoke activity especially after a whole day of talking at work.





  1. Identify the Source of Vocal Symptoms
  2. Define specific occurrences/attacks, evaluation of specific situations
  3. Vocal Pacing
  4. Use of amplifiers for lectures/training employees more than 20.
  5. Frequent sips of water between clients or queuing.
  6. Warm ups before the start of the work “day”
  7. Cool downs and Voice rest after work
  8. Plan more non-voice activity for leisure (no videoke after work, reduce recreational singing events)
  9. Avoid food that irritates the vocal cords (mint, caffeine, dairy products, etc.)
