For English, I heard people pronounce short vowels not in accent syllable as schewa sounds but I heard they pronounce longer “i” sounds (find, kind, kite) like ah.

For example, “find”. They pronounce it almost like “fahnd” or “fah-uhnd”. How do they pronounce it actually?

And I think this is typical to American people. British say more clearly like “fah-ee-nd”

Answer

Pronunciation of vowel sounds varies widely between regions, in the US also. For example, there is a passage in a famous novel where people from the North think the people from the South want their 'rats'. But actually, they are just pronouncing 'rights' in a different accent.

My name, DAN for example.      Normally it's one syllable (and one vowel sound).  But where I live in the upper Midwest, some people pronounce like  'Dee-yun'. And in the South where I was born, people pronounce it more like 'Day-un'.

Answer

There are many distinct regional dialects in the UK. But the most standard way to pronounce 'find' would be using the /aɪ/ diphthong (as per the International Phonetic Alphabet).

As such, it roughly rhymes with eye, my, buy, try, aisle, die, tie, pie, hi, etc.
