CSD 360: How Resonation Works

vocal tract

multiple containers of air that vibrate at specific frequencies

Container 1

the air behind the tongue; from the top of the larynx to the hump of the tongue

Container 2

the air above and in front of the tongue; from the hump of the tongue to the tip of the lips

resonator

the vocal tract, can change shapes and sizes and frequencies

containers of air

The ________ __ ___ inside the vocal tract change shape and size when the muscles of the tongue, neck, jaw, soft palate, lips, and pharynx engage.

higher

If the jaw drops, Container 1 (behind the tongue) gets smaller and Container 2 (in the front of the tongue) gets larger. The frequency of formant 1 gets ______.

lower

If the jaw drops, Container 1 (behind the tongue) gets smaller and Container 2 (in front of the tongue) gets larger. The frequency of formant 2 gets ______.

larger

If the lips come forward both containers of air become

lower

If the lips come forward, the frequencies of both containers of air get

raises

Both Containers 1 and 2 get smaller if the larynx

higher

If the larynx raises, the frequency of Formant 1 and 2 gets

lowers

Both containers 1 and 2 get larger if the larynx

lower

If the larynx lowers, the frequency of Formant 1 and 2 gets
