Mental exercise: Fill in the missing labels in the Cycle of Phonation below
The Cycle of Phonation begins when the brain sends the signal to inhale. Then, it follows and repeats the following:
Air is released through a controlled relaxation of the inhalation muscles, forcing air (our breath) upwards from the lungs and through the larynx at the top of the trachea.
The moving air passes through the larynx where the vocal folds are housed. When the folds are brought together against the air, they vibrate at varying speeds, depending on how tight or loose the folds are.
The movement of the vocal folds changes the way the air molecules are moved, forming a sound wave (fundamental frequency). This wave is then enhanced and molded into desired tones in the resonating chambers of space, known as the vocal tract. The vocal tract includes the pharynx (throat), oral cavities and nasal cavities.
The enhanced frequency is then further refined and can be intentionally disrupted to create identifiable shapes and sounds (vowels and consonants) by adjusting the muscles related to the tongue, jaw and lips.
Name an instrument other than the voice and identify its Actuator, Vibrator, Resonator and Articulator
