The jaw movements that occur during speech to articulate and resonate vocal sounds are simple, small and loose. They should be the same type of movements you created with your hand pivoting your jaw open and closed.
You can feel constant loose jaw movements during a simple syllable repetition.
Pretend you are learning a new language that has only two sounds: a consonant and a vowel. Using a mirror for visual confirmation, practice your new languages with your jaw dropping for each vowel, then being lifted upward briefly for the consonant.
Imagine you are a marionette-puppet, with only a heavy wooden jaw and a string to articulate with, or that you’re a visitor from outer space who has a simple jaw joint on a hinge and a simple language. Keep your tongue absolutely still on the floor of the mouth. Remember: Marionettes and Martians don’t have tongues!
Keep the upper lip in neutral half-open umbrella position. The jaw starts in “mouth-open for breathing and vocalizing position”:
1. MARTIAN: AnAnAnAnAnAnAnAnAnAnAnAnAnAnA….
Tip 1: Say the “A” vowel like “ah”; the arrows mean your jaw drops for each new “ah”
Tip 2: Use your regular speech speed or about 5 syllables/second.
Tip 3: Don’t cheat by articulating “n” with your tongue tip. The “n” will be automatic when the jaw lifts your tongue mass up to the roof of your mouth!
2. VENUTIAN: AvAvAvAvAvAvAvAvAvAvAvAvAvAvAvAv…
Tip 1: Let gravity be responsible for the jaw drop on each “ah”.
Tip 2: Don’t cheat by articulating “v” with lower-lip movement…
The “v” will be automatic when the jaw lifts your lower lip up to your upper teeth!
3. SATURNIAN: AsAsAsAsAsAsAsAsAsAsAsAsAsAsAsAs…
Tip 1: Remember not to use an exaggerated slow rate. Do use your regular speech speed.
Tip 2: Don’t cheat by articulating “s” with your tongue tip. The “s” will be automatic when the jaw carries your tongue mass up to the roof of your mouth!
