Did you ever notice that people who smoke a lot have rough, raspy voices? The acid can irritate your vocal cords.ДЄllergies or smoking can also irritate your vocal cords (another good reason not to start messing with cigarettes). Sometimes the stomach acid that helps break down that food comes back up your swallowing tube.

Just like you have a tube for air to go into and out of your lungs, you have a tube for food to go into your stomach. Even a lot of loud singing can irritate your vocal cords and cause laryngitis.ДЄlthough it sounds odd, sometimes your stomach can cause laryngitis. Or you might be cheering on your favorite team, yelling with the crowd during a great play - touchdown! Or you may be in a group of noisy kids and have to talk loudly to be heard. You may be hollering at your younger brother or sister. In kids, laryngitis often comes from too much yelling and screaming. This is called laryngitis (say: lair-in-JYE-tis). When your cords become inflamed and swollen, they can't work properly. Do you feel the vibrations along your throat coming from your vocal cords? What Causes Laryngitis? Make your voice go from deep to high pitch and back again. When you talk with a higher pitched voice, you tighten the vocal cords and make them smaller. Although you don't even think about it, every time you want to talk with a deeper voice you lengthen and relax these vocal muscles. You can make different sounds by lengthening or shortening, or tensing or relaxing, the vocal cords. The sound from these vibrations goes up your throat and comes out your mouth as 'Chocolate is the best flavor!' (or whatever your favorite flavor of ice cream happens to be). Now the air from your lungs has to pass through a smaller space. When you breathe, your vocal cords are relaxed and open so that you can get air into and out of your lungs.Д«ut when you decide to say something, these cords come together. Inside your larynx are two bands of muscles called vocal cords, or vocal folds. Answer the question: 'What's your favorite flavor of ice cream?'ДЄt the top of your windpipe - also called your trachea (say: TRAY-kee-uh) - is your larynx (say: LAIR-inks), or voice box. Here's the way your voice works - and why sometimes it doesn't. Maybe you were croaking like a frog or when you tried to speak, only some of the words came out. Did you ever hear someone say, 'I lost my voice'? Did you think: 'What did you do with it?' Or maybe you woke up one morning and your voice sounded funny when you tried to talk.
