Four ways to learn how to use your voice correctly

1. Breathing exercises

Stand naturally, eyes level, shoulders, chest, arms relaxed, hands overlapping, palm on the "Dantian point" (4 fingers under the umbilical) position.

During exhalation, the umbilicus and umbilicus are forced to concave inward, while during inhalation, the umbilicus and umbilicus are forced to protrude outward, exhaling and inhaling each 16 times per minute. Practice 20 minutes a day for a week.

2. Yawning technique

Just as you would with a yawn, open your teeth easily and naturally, raise your palate, and take a deep breath. Remember, don't close your mouth as soon as you've taken in enough air, but stay still, imagining you're still breathing in, for as long as you can before you relax.

This move can be practiced anytime, anywhere. If you are in a public place, it is not convenient to "yawn", you can also do the silent yawn exercise.

3. Tongue extension and relaxation

Look up and open the mouth, relax the jaw, so that the upper lip naturally opens up, the jaw joint then loosens, the mouth is erect duck egg shape, and then let the tongue naturally forward, feeling that the root of the tongue will push the tongue out, the tip of the tongue as much as possible to relax, and then naturally shrink. Repeat the exercise 20 to 30 times per group, 4 to 5 groups per day.

4. Flat forward beep method

Keep your upper body steady, close your lips naturally, inhale deeply, and air is emitted from your lungs. When you exhale, your lips vibrate and your vocal cords vibrate forward, making a beep sound.

This action relaxes the vocal cords. Repeat the exercise 20 times per group, 3 to 4 sets per day.
