Voice production refers to the process by which sound is generated in the human body, primarily through the larynx, or voice box. When air from the lungs passes through the vocal cords, they vibrate, creating sound waves. The pitch and volume of the voice can be altered by adjusting the tension and length of the vocal cords, as well as the airflow. The sound produced in the larynx is then shaped by the throat, mouth, and nasal passages. These structures act as resonators and articulators, modifying the sound to form distinct speech sounds. Proper voice production is essential for effective communication and can be enhanced through techniques used in singing and public speaking.
