Very strickly speaking, what could be the ABSOLUTELY RIGHT way of pronouncing "the".
I'm aware of the rule that "the" is pronounced as "Di:" (with a stressed long "i:" vowel), & if it's NOT followed by a vowel then it's pronounced merely as "D@" with "schwa".
Now, what I'm bit at sea about is when it's followed by a vowel, WHETHER the pronounciation of "i" vowel is longer stressed vowel, as in "si:t" (seat) or is it the shorter stressed vowel, as in pA:.ti (party) ???
