A digraph is two letters that spell one sound. Digraphs that spell consonant sounds include the letter pairs sh, ch, th, wh, ck, ph, ng. Digraphs that spell vowel sounds include the letter pairs ai, ay, ee, ea, ie, ei, oo, ou. ow, oe, oo, ue, ey, ay, oy, oi, au, aw.
Some texts speak very loosely when they say there are five vowels. They mean to say that there are five vowel letters (a, e, i, o, u). Actually, y and w are also used as vowel letters. That is, these seven letters and combinations of them are used to represent vowels. A vowel is something you hear, not something you see. The symbols (letters) you see are not, strictly speaking, vowels. They represent vowels, which is quite different. Depending on which variety of English you are talking about there are 14 or 15 vowels.
