His vocal cords will become thicker, longer and located further apart, so the resulting sound will be lower and larger. Finally, by nature a teenage boy will generally lose the ability to issue a pitched voice.

Sometimes these teens voice suddenly changed from low to pitched voice and then back into a low voice again, causing a sense of shame. This is because he has not so familiar with his voice box that is now getting bigger. He still had to train themselves away to be able to use the muscles of the vocal cords properly.
