Learn more about speech … This capacity can be accomplished in any volume from a soft whisper to a loud shout by varying the force and volume of air expelled from the lungs. Try saying a few to see which ones use your lips the most. The biggest change to allow speech is a change in the position of the epiglottis, which is a leaf-shaped piece of cartilage that covers the opening of the larynx while swallowing in an effort to prevent choking. Speaking in louder tones is accomplished by greater force on the air expelled from the lungs. We buzz sound around in here when we make M or N sounds. This sequence is repeated in fine detail during speech. Functional speech sound disorders include those related to the motor production of speech sounds and those related to the linguistic aspects of speech production. This makes it much easier to remember their location and names, but this division also helps us remember their functions. … The front of the tongue may move upward to contact the hard palate while the back of the tongue is depressed.
