1 How we make a sound?

ans: When we tries to make a sound,we take air inside air tube. These air goes to larynx.In larynx,there is a vocal cord. The vocal cord vibrate the air to produce sounds.In between the vocal folds there is glottis which lengthen and shorten the vocal cord to produce different type of sound in different amplitude. Then this simple sound goes to our mouth where we uses tongue, teeth,etc to pronounciate the sound clearly. thank you
