Vowel sounds are:
(and Y as a relative as in by and my).
The vowels have two sounds.
a can be pronounced ‘ah’ as in cat or ‘ay’ as in mate.
e can be pronounced ‘eh’ as in pet or ‘ee’ as in Pete.
i can be pronounced ‘ih’ as in kit or ‘igh’ as in kite.
o can be pronounced ‘ogh’ as in top or ‘owe’ as mope.
u can be pronounced ‘ugh’ as in cut or ‘yew’ as in cute.
It is vital that you know words cannot be created without vowels (including y as vowel relative). There is also a strong probability that if it isn’t a short vowel then it will be a long one.
If you really want to impress, then try to remember a short vowel has a smiley on the top of the letter and a long vowel has a line (see the pictures below). Why not try working out the vowel sound out with subject words using the smiley or line?
ah or ay for a
eh or ee for e and so on.
