In phonetics, a vowel is a sound in spoken language, with two competing definitions. In the more common phonetic definition, a vowel is a sound pronounced with an open vocal tract, so that the tongue does not touch the lips, teeth, or roof of the mouth, such as the English ah /ÉË/ or oh /oÊ/. There is no build-up of air pressure at any point above the glottis.
Define syllable. 1  A syllable is the sound of a vowel (A, E, I, O, U) that is created when pronouncing the letters A, E, I, O, U, or Y. 2  The letter Y is a vowel only if it creates an A, E, I, O, or U sound. 3  When two (or more) vowels are next to each other, the number of syllables depends on the number of vowel sounds.
