Hi Vaok,

I think partially what you're asking for is what is known as minimal pairs; that is words that differ by only one sound.

Try these exercises for a lengthy list of minimal pairs in a quiz format.

Hope that helps.

thank you.
i want to know the rules of the pronunciation of letter or letters (in a fixed group like "tion", ture, ai, ee, th, ect.)

Are there any rules like that?
