Vocal cords are important organs for pronunciation. When the vocal cords move to the midline and the glottis close, air flows out of the lungs and impacts the vocal cords, which will make a sound. This sound is called pitch. Then, all kinds of sounds and sounds are made through the ringing of throat cavity, pharynx cavity, nasal cavity and chest cavity, as well as the movement of lips, teeth, tongue, soft palate and cheeks in coordination with the nervous system. Pronunciation, as opposed to breathing, is a random action. You can also act at will. The sound depends on the length of vocal cords, and tension has the power to exhale air. If the tension of vocal cords increases, they become shorter and thinner, and the vibration frequency is higher, so a loud sound is made, otherwise a bass is formed. Incomplete opening and closing of vocal cords can lead to hoarseness, and the main reason for your hoarseness is singing. The processing method is as follows: 1.
