Know your vocal cords and play your voice chords

Welcome to the World's first online Vocal (voice) Clinic

Vocal care is  as important as dental or any other health care more importantantly for singers and speakers or any other professionals who are involved with using vocal cords a lot.

Knowing how normal voice is produced and how it works with speaking and singing helps us understand,prevent as well as manage voice problems.

The "spoken word" results from three components of voice production: voiced sound, resonance, and articulation.
  • Voiced sound: The basic sound produced by vocal fold vibration is called "voiced sound." This is frequently described as a "buzzy" sound. Voiced sound for singing differs significantly from voiced sound for speech.
  • Resonance: Voice sound is amplified and modified by the vocal tract (consists of throat, mouth cavity, and nasal passages) resonators . The resonators produce a person's recognizable voice.
  • Articulation: The vocal tract articulators (consists of tongue, soft palate, and lips) modify the voiced sound. The articulators produce recognizable words.

 Mechanism of Voice production

Speaking and singing involve a voice mechanism that is composed of three subsystems.                                                                     Each system is composed of different parts of the body and has specific roles in voice production.                                              Three Voice subsystems 

SystemComponants of Voice systemHow do they help in Voice Production

Air pressure system

Diaphragm, chest muscles, ribs, abdominal muscles and Lungs.

Provides air and controls the pressure. Just like when you blow air into a flute or  any wind instrument.

Vibratory system

Voice box (larynx) functions  like the a mouth piece of a wind instrument. It is made up of cartilage bones, fibrous membranes and muscles creating a tube like structure with empty space, and in between the space the vocal folds are arranged  like a Gate to modulate the voice.

Vocal folds (cords) vibrate,  sound waves are produced known as "voiced sound," or "buzzy sound"

Resonating system

Vocal tract: Consists of Throat (pharynx), Oral cavity, Nasal passages helps in transforming and transmitting the sound out of the body.

Transforms the "vibratory sound" into a person's recognizable voice

 Damage can occur in any one or all the three subsystems of voice system.

Any disturbance in the Vibratory System results in Voice problems.

 Function of the Voice box or Larynx

 Function of the voice box is to open and close the glottis  which is the space between the two vocal folds.

  •  In breathing: Glottis opens to transmit air. 
  •  In coughing: Glottis closes and then opens abruptly when the respiratory tract is irritated by any foriegn  bodies  such  as  Dust particles, Allergens, Bacteria,Virus etc.
  •  In swallowing: Glottis closes so that food won't enter into the respiratory tract through Larynx.
  •  In voice Production: Glottis opens and closes to adjust the  vocal fold tension.


Voice Box or Larynx  is made up of different components as shown in the picture
