"vocal folds" 的定义和意义

What are "vocal folds"?

The vocal folds, also known as vocal cords, are delicate structures located within the larynx that play a central role in human communication. When air passes through the vocal folds, they vibrate, producing sound waves that can be shaped into speech, singing, or other vocalizations. The tension and position of the vocal folds can be adjusted to control pitch and volume, allowing for a wide range of vocal expressions.
