What Are Diphthongs?

FAQs About Diphthongs

How are diphthongs different from vowel digraphs? While both involve two vowel sounds, diphthongs are specifically about the change in sound quality during pronunciation. Vowel digraphs are spelling patterns where two vowels represent a single sound, which may or may not be a diphthong.
Are diphthongs the same in all English accents? While the core diphthongs are generally consistent across English accents, their exact pronunciation can vary. For example, the /aʊ/ sound in “house” might be pronounced slightly differently in British and American English.
How can I practice pronouncing diphthongs? Practice by exaggerating the movement between the two vowel sounds, then gradually make the transition smoother. Use minimal pairs (words that differ only in one sound) to distinguish between similar diphthongs and monophthongs (single vowel sounds).
