Introduction to Diphthongs
Diphthongs are complex vowel sounds
that begin with one vowel sound and glide into another within the same
syllable. They are essential in the English language as they contribute to the
pronunciation and meaning of words. In this lesson, we will focus on the
diphthong /aʊ/, which is found in many common English words.
The /aʊ/ diphthong starts with an
open front unrounded vowel /a/ and glides towards a close back rounded vowel
/ʊ/. This combination can be heard in words like "house" and
"cow".
Pronunciation
Guide
To produce the /aʊ/ sound:
- Start with your mouth open wide, as if saying the vowel
sound in "cat" (/a/).
- Glide your tongue upwards and slightly back, rounding
your lips, as if transitioning into the vowel sound in "put"
(/ʊ/).
- Practise by slowly moving from /a/ to /ʊ/ to get a
smooth transition.
