Breath support part of system 1 comes from your respiratory system. When we want to speak, we take a breath inhale and then start speaking on the exhale. It is this flow of air moving up the windpipe and through the voice box between the vocal folds that starts and keeps the vocal folds vibrating until you stop talking or run out of breath. Vocal fold vibration is the sound source: it is also called phonation system 2.
The vocal folds are two small muscles that have a moist covering, within the larynx. When you breathe, the vocal folds are open to allow air to flow from your upper airway into your trachea and lungs. When you want to speak, you close your vocal folds and begin to exhale, causing an increase in pressure that starts them vibrating cyclic opening and closing. If you need more volume, just increase the breath-energy emanating from your diaphragmatic area by taking a deep breath, then consciously contracting the diaphragm.
This will support the sound with a full cushion of air. Experts disagree as to whether or not whispering damages the voice. Rather, the larynx is bypassed and plays no part in producing the sound. However, if you choose to whisper, try not to squeeze your vocal cords together with pressure. Aside from usually being unnecessary, it can be harmful. Download Now! Are You Hoarse?

What can you do to avoid this undesirable scenario? Keep yourself Hydrated Keeping your vocal folds moist is very important. Try Standing More Often When possible, try standing during meetings. Foods, Drinks, and Habits to Avoid Some people report that dairy products such as milk and yogurt will coat your throat, which causes the sound coming out of your mouth to be muffled, giving you that feeling that you want to keep clearing your throat.
Try to Avoid Clearing Your Throat Clearing your throat replaces the gentle action of air passing through the vocal cords with them being slammed together. You can feel that speaking involves vibration.
Vocal cords are stretchy flaps of skin in your throat that vibrate to make a sound. In order to speak, we move air past our vocal cords, which makes them vibrate. The vocal cords must be in good shape for speech to sound clear and loud. Air being let out of a balloon mimics how air passes through the vocal cords to produce sound. We change the sounds we make by stretching and contracting the muscles attached to our vocal cords.
The sounds found in the word "gllloooooooo" stretch the vocal cords in different ways. When the vocal cords are stretched out we make high sounds and when they are loose we make lower sounds. A great video of vocal cords in action courtesy of the filming of a laryngoscopy procedure can be found at Auditory Neuroscience.
Adjusting the tension in the opening of a balloon as the air comes out demonstrates how to vary pitch. As air is forced out of a balloon or whoopee cushion's narrow opening, it makes the rubber vibrate. This in turn makes the air surrounding the rubber vibrate, propagating waves through the air to your ears, translating into sound.
When blowing through their "fart whistles," students get to both see and feel the vibrations of the sound. When you speak, you use the muscles in your tongue, lips, jaw, and pharynx to make the vocal cord vibrations into words. Adjusting the neck and "mouth" of the balloon mimics how human voices are changed by the actions of their anatomy.
Describe how sound is produced. Per Class: balloons 1 for each student a chair 10—15 pairs of scissors whoopee cushion for optional activity in Part 3. Part 1 When we are talking to each other, which parts of our bodies form the sounds and words we use?
