TERM 1 Source Filter Theory DEFINITION 1 Theory that describes how the vocal tract filters glottal sound waves to generate different vowels This is due to resonance TERM 2 Myoelastic-Aerodynamic Theory of Phonation DEFINITION 2 Theory that explains vocal fold vibration in terms of muscular, elastic recoil and aerodynamic forces. Muscle forces are used to manage phonation but not the move the vocal folds back and forth each cycle TERM 3 Bernouli Principle DEFINITION 3 According to this principle, a gas - such as air - passing through a narrow channel increases in velocity and decreases in pressure TERM 4 Diaphragm DEFINITION 4 Forms the roof of the abdominal cavity, and the floor of the thoracic cavity It is the main muscle for inspiration When contracts, it lowers the floor beneath the lungs and extends them vertically Pushes out the base of rib cage Pushes down on the abdomen and compresses the stomach and other organs TERM 5 Spirometry DEFINITION 5 Device that measures the amount of air an individual inhales and the rate at which the air moves in and out of their lungs Records either volume or flow Lung volumes and capacities are measured in relation to REL Time is on x-axis Inspiration and expiration of y-axis TERM 6 Rest Expiratory Level (REL) DEFINITION 6 The 0 point on a relaxation pressure graph. The state of equilibrium during which Pair = Patmos TERM 7 Speech Breathing DEFINITION 7 Devote ~10% of cycle time to inhalation, and ~90% to exhalation Cycle time depends on what's needed, could be 20 seconds or more Exchange greater amount (volume) of air than quiet breathing TERM 8 Feedback DEFINITION 8 Refers to the transfer of part of the output of a system, back to the input to regulate and correct any errors in the input TERM 9 Feedforward DEFINITION 9 Signals that make adjustments at the periphery so that the system is primed to move in efficient, coordinated manners. Previously learned commands TERM 10 Efference Copy DEFINITION 10 Refers to the notion that when a neural motor command signal is sent to a muscle or structure, a second simultaneous "copy" of the signal is transmitted to various sensory systems as well
