How People Produce Sound

From this lab I have learned that a sound can be produced with many different parts combined of your mouth. This is mainly when your breath is party stopped by your tongue, teeth, or lips. Some sounds are made from similar movement inside your mouth, such as the letter t and d. When your mouth muscles pronounce these letters, your tongue starts at the top part of your mouth and goes down, and your lower yaw goes down. However, there are many different letters, and all of them make specific mouth movements. The vowels, (a,e,i,o,u,) and the letters k and g are made without closing your mouth at all or without having anything block the sound from your vocal cord. These are called open letters. All of the other letters are called stopped letters, since there is some sort of a barrier from when they leave the vocal cord to when they are outside your body. Another thing I learned from this lab is that we have true and false vocal cords. From this experience I am now also able to visualize a vocal cord, which will be very helpful as we continue studying sound.
