Voice and Throat disorders: Symptomps and Treatment

For voice to be produced, air from the lungs travels up the throat through the trachea and the larynx (voice box) and finally out through the mouth where speech is shaped by the tongue and lips. It is in the voice box that sound is produced when the air passes across the vocal chords which are two fibrous bands, causing them to vibrate.
