Diphthongs: The “Great Day” vowel

As all our trainees know, we use nicknames for each of the vowel sounds.  “Great Day” is the nickname we use for one of the English vowels.  It is a diphthong, and  English is a language with many diphthongs.  A diphthong is a single gliding sound consisting of two vowels. Both words of the expression "great day" are said with the diphthong [ei].  The vowel in each word  glides from [e] to [i].

Mastering your diphthong pronunciations is one of the keys to clear English speech!
