Which part of human body is responsible for the voice production?
Larynx
The mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx (voice box), and the articulators. The lung, the "pump" must produce adequate airflow and air pressure to vibrate vocal folds.
In humans, the sound of speech is produced by the Larynx or Vocal cord.
