A syllable is a single, unbroken sound of a spoken (or written) word. Syllables usually contain a vowel and accompanying consonants. Sometimes syllables are referred to as the 'beats' of spoken language. ... The number of times you hear a vowel (a, e, i , o, u) in a word is equal to the number of syllables a word has.
