To form words, air is first breathed through the trachea as the vocal folds, or cords, vibrate. These vibrations help create the raw sound of voice. This sound is altered and amplified by the nasal cavity, throat and mouth to form a person’s distinct voice. The lips and tongue then help turn these sounds into recognizable words.
