Voice is the result of a smooth combination between the cerebral cortex, the transmission nerves and the place where sound is emitted is the larynx, mouth, nose, pharynx, teeth, and lips.
The larynx is the narrowest organ of the airways, the source of sound. Although the larynx is not the decisive organ for the production of voice, speech is mainly produced by the larynx.
The larynx is composed of two funnels connected to each other at the narrowest space, the glottis, the distance between the two vocal cords separates the upper part of the glottis and the lower part of the glottis.
The glottis has 3 main functions: one is the respiratory function; the second is the function of protecting the airways: thanks to two reflexes, constriction, to prevent foreign bodies (liquid, solid) from falling into the trachea, lungs and cough reflex to expel foreign objects; three is the function of pronunciation, sound and voice.
Sound is produced when air passing through the glottis vibrates the two vocal cords that make up speech.
When pronouncing two closed vocal cords, the sound comes out evenly, the inner voice has timbre, creating a unique sound of each person. If when pronouncing, the two vocal cords are not closed, the voice will be hoarse, uneven voice, loss of voice, loss of timbre…
