Capther 4.- Diphthongs and Triphthongs

         Diphthongs consist of a movement from one vowel to another. It can be seen as a group of vowel sounds that are consistently longer in a given context in a label tens. English speakers seem to be more sensitive to the quality of  diphthongs as in beard. They are divided in two groups, the firs are three centring  diphthongs as in the word get and the second group are five closing Diphthongs as in the words home and face. Besides, thiphtongs are seem as complex English vowel consonant sounds because they are difficult to pronounce pupils do not notice the difference from Diphthongs  or long vowel sounds. It is a glide from one vowel to another then to a third as in the words “Diana”, “fewer”, “hour” all are pronounced rapidly without stop so it never is notice as in connecting speech in complete sentences when native speakers do.
