Pronunciation of pronouns in different syntactic functions

Answer

If you stress a pronoun in the sentence, it will be pronounced normally.

If you don't stress a pronoun, it will be reduced to "weak form." For example,

HE wants to drink water.  -> HE = /hiː/ -> You stress the word "he."

He wants to drink WATER. -> He = /hi/ -> You stress the word "water."
