Because u know that I favour modernisation of English spelling, u find it hard to accept that I know much about the English spelling system, but I do. I spent many years analysing it.
The concept of 'schwa' or unstressed vowels (the 44th sound) is a little tricky to grasp. (English is unusual in generally having just one stressed vowel per word, e.g. abAndon, invEstigate, Animal). But this is not of great importance with beginners learning to read and write, as most of the words they are first introduced to consist of just one syllable.
I hope that the list I pasted in makes the other 43 sounds as clear as possible. The first letter, or combination of letters shown first, is the main spelling for each of them, also shown in the first word. The other words show the alternative spellings for each of them. I have simply tried to provide a concise summary of the English spelling system.
There are a few regional differences in pronunciation.
1)Many Liverpudleans don't distinguish between the short /u/ of 'bus, but, cut' and that of 'put, pull, push'. They use just the latter.
2)Southerners pronounce the 'a' of 'bath, path, grass' with the same sound as in 'father' (not with that of 'cat, mat, sat'), but many others don't.
3)In Scotland the long oo of 'pool, fool, school' tends to be shorter.
4)The Irish and the Americans pronounce the r ending of 'mother, father, other', (known as rhotic but most UK speakers don't.
