Vietnamese diphthongs and triphthongs are sounds formed by the combination of two or more vowels in a single syllable. In the Northern Vietnamese Dialect, the sound usually begins as one vowel and then moves toward the sound of another vowel as listed below. However, diphthongs and triphthongs are pronounced quite differently in the Southern Vietnamese Dialect. Learn the Southern Vietnamese Diphthongs and Triphthongs in the Online Classroom (Course 2).
