V. interesting Kew.
BtS,orthography (writing) has very little relation to pronuniciation.
George Bernard Shaw made the point for example that in English, 'ghoti' could be a written form of the spoken word 'fish'.
How so?
'gh' as in the end sound in 'enough'
'o' as in the first vowel in 'women'
'ti' as in the middle sound in 'motion'
The answer to it all is to use the International Phonetic Alphabet and free youselves from the tyranny of erratic spelling patterns as all salts do!
(I can pronounce those-had an Irish bf for years!)
