How did Shakespeare say have?

Answer 1

Have. As in "I have of late, but wherefore I know not" (Hamlet, 2,2) or "Have you no modesty, no maiden shame?" (Midsummer Night's Dream 3,2) or "and all their yesterdays have lighted fools the way to dusty death." (Macbeth 5,5).

It is believed that he would have pronounced the word with a broad vowel. Imagine how Long John Silver would say it.

If you are thinking about the word "hath", it means "has". Just imagine that they spoke with a lisp when they said "has".
