VOWELS & DIPHTHONGS
Prepared by:

2. The word diphthong comes from the Latin word "diphthongus" and the Greek word "diphthongos," meaning "having two sounds."
Diphthongs begin with one vowel sound and change to another vowel sound in the same syllable. Your mouth position changes slightly through the vowel sound. 

3. /eɪ/ - long A sound sliding into a long E sound.
/eɪ/ - long A sound sliding into a long E sound.  
/aɪ/ - a long I sound sliding into a long E sound. 
/ɔɪ/ -long O sound that quickly slides into a long E sound.
/ɪə/ -long E sound sliding into an Ur sound.
/eə/ -long A sound sliding into an Ur sound. 
/aʊ/ -short A sound  sliding into an “oo sound” .
/oʊ/ - single long O sound. As a diphthong, it has a long O sound sliding into an “oo sound” .

5. /eɪ/ (Long A sound)
This diphthong is similar to the long A sound. It is pronounced as a long A sound sliding into a long E sound.  Some dialects pronounce the long A sound as one single sound (like in bake and late). Others pronounce it as two vowel sounds. It really depends on where you live. People with southern accents (from the south part of the United States) will stretch out the diphthong more.

may

7. /aɪ/
This diphthong is pronounced as a long I sound sliding into a long E sound.   Again, this sound can vary from dialect to dialect. Some dialects pronounce the long I sound in the following words as one single sound. Some dialects pronounce the vowel sound more like the "AH" sound you would here in "ball". Others pronounce it as two vowel sounds.
