How to pronounce the 26-letter vowel phonetic symbol?

The 26-letter vowel phonetic symbols are as follows:

When vowels are pronounced, the vocal cords vibrate and the airflow through the mouth is unimpeded. Vowels are divided into monophthongs and diphthongs. When pronouncing a single vowel, the shape of the lips and the position of the tongue remain unchanged. Diphthongs contains two factors. When pronounced, it slides from one vowel to another. The difference of vowels depends on the position of the tongue, the degree of gum opening and closing, the size and roundness of the lips.

Monovowels are divided into front vowels, middle vowels and back vowels. The difference is whether the tongue is in the front, middle or back of the mouth. The opening and closing of gums determines whether vowels are open vowels, semi-open vowels, semi-closed vowels or compound vowels.
