Review of Monday - Speech Production
In response to those who missed Monday - and to help EVERYONE continue to think about the objectives from Monday. I want to post some questions relative to the OBJECTIVES from Monday. None of you want a professor to LECTURE and TELL you information so let's see if by using our resources, blog discussion and in class dicussion we can deepen our understanding of the important concepts in this class. Let's start this discussion considering the path AIR takes to produce speech. What happens to air or what does the air do in each of the four processes. Try to use vocabulary a anyone would understand if they did not know the terms (respiration, phonation, resonation and articulation).

OK...so the path air takes to makes speech starts with the brain. The brain, which serves as a computer center, sends the information needed to the lips, teeth, tongue, alveolar ridge, hard plate, soft plate, and mandible. Those parts of the mouth work together to articulate the sounds the brain told it to say. Then the brain tells the entire mouth, pharynx, and nasal cavitites to work with the prvious parts to make the tone needed to convey the initial message. Next, the brain tells the vocal folds of the larynx to add the actual noise or sound so that the message can be heard. Lastly, the brain tells the body to inhale using the thoracic muscles and exhale using the abdominal muscles which allows the actual speech to not only be heard, but also be understood, clear, and consistent.
....Yes, I know this is a very drawn out version, but that is the route it takes, which happens very fast as do most things connected to brain function in our bodies.
Yes, the MESSAGE of WHAT we want to say starts in the brain. You have the parts here. But, lets think CHRONOLOGICALLY. Can the lips and mouth produce a sound without any air? Where does the air have to start FIRST?
If the brain creating the message is the FIRST step. What is the SECOND step? Where does the body get the air to create speech?
hmm....are we talking about inhalation here? I'm still a little confused I guess. The air is inhaled through the mouth or nose and then goes to the brain first I think, and then as the brain sends messages out, the air is also pushed out through the mouth to help produce speech...? Is this way off?
What do the lungs do? The larnyx? The vocal folds? Does the graphic in the book help? What about the interactive website in Blackboard?

IF step 1 is the creation of a mesage by the brain then STEP 2 would hae to be the production of air by the lungs when one inhales STEP 3 is the maintainence of the stream of air under pressure up through the larynx then the vocal folds (folded tissue) in the "voice box". This force of air causes vibration across these vocal folds. STEP 4 is upward flow of air through the nasal cavity which allows for tone changes (resonation) STEP 5 I believe is the production of speech in the oral cavity or mouth by exhaling the air that was produced to create speech. Changing the sound of hat is being produced by changing the positions of the tongue, teeth and or lips.
You have that air traveling!! Guiding and shaping it from inhaling through the nose, traveling through all the proper places until it makes it way to SPEECH!
