This video describes vowels in English.
What are vowel sounds?
English has fifteen vowel sounds represented by the letters a, e, i, o, and u. The letters y, w, and gh are also commonly used in vowel sound-spellings. Vowel sounds are produced with a relatively open vocal tract. Consonant sounds, in contrast, are created by pushing air through a small opening in the vocal tract or by building up air in the vocal tract, then releasing it.

Categories of the vowel sounds
Vowel sounds are divided into the following three categories:

Long vowels (vowels that sound like the letter name)
Short vowels (the most common sound for a single vowel spelling)
Other vowels (the remaining vowel sounds)
