Sound
The sound contains sounds made by humans using vocal folds for speaking, reading, singing, laughing, crying, screaming etc. Human voices are particularly part of the production of human sounds where the vocal fold is the main source of sound. In general, the mechanisms for generating human voices can be divided into three parts; lungs, vocal folds in larynx, and articulator. Peparu must produce enough airflow and air pressure to vibrate the vocal folds. The vocal fold is a vibrating valve that cuts off the airflow from the lungs into the audible pulse that forms the source of the larynx sound. The larinks muscles adjust the length and tension of the vocal fold to the 'fine tone' tone and tone. The dismantling articulator and sound filters arising from the larinks and to some extent may interact with the larynx airflow to amplify it or weaken it as a sound source.
