Diphthongs
Diphthongs are those sounds that consist of a movement or glide from one
vowel to another. The first part of a diphthong is always longer and stronger
than the second part; as the sound glides into the second part of the diphthong
the loudness of the sound decreases.
One of the most frequent errors made by language learners is to use pure vowels
instead of diphthongs.
