Vowel pronunciation mode

When vowels are pronounced, the highest point of the tongue moves to the front of the mouth and arches slightly. When vowels are pronounced, the root of the tongue is raised to the soft palate. Tongue position and lip shape are a standard for vowel classification.

When pronouncing, the airflow exhaled from the lungs passes through the mouth as a resonator, producing the sound with the least resistance and no fricative sound. Although the vocal cords usually vibrate when vowels are pronounced, they can also be voiced or voiced.

When vowels are pronounced, the air flow from the lungs impacts the vocal cords through the glottis, so that the vocal cords vibrate evenly, and then the vibrating air flow passes through the mouth unimpeded, making different sounds through the adjustment of the tongue and lips. Vowels vibrate when pronounced, so they are voiced. In some languages, the vocal cords do not vibrate when vowels are pronounced, and unvoiced vowels are produced.
