ANATOMY

Detailed explanation-1: -Vocal cords: Your vocal cords, or vocal folds, open, close and vibrate as air passes through to create sounds and speech.

Detailed explanation-2: -The larynx plays an essential role in human speech. During sound production, the vocal cords close together and vibrate as air expelled from the lungs passes between them.

Detailed explanation-3: -The vocal folds produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs. This vibration produces the sound wave for your voice. In order for the sound to be clear and not raspy or hoarse, the vocal folds must vibrate together symmetrically and regularly.

Detailed explanation-4: -Speech occurs when air flows from the lungs, up the windpipe (trachea) and through the voice box (larynx). This causes the vocal cords to vibrate, creating sound.

Detailed explanation-5: -The LARYNX (voice box) contains your vocal cords. When moving air is breathed in and out, it creates voice sounds.
