Sometimes, when I watch American films, I often hear people say "ɪt zɑːn ðə ˈteɪbl" (it is on the table).
I learned in textbook that "it is" can be contracted as "it's" and since "t" is voiceless so we have to pronounce "it's" as "ɪts" not "ɪtz".
But people, especially American ones often say "ɪt zɑːn ðə ˈteɪbl" (it is on the table).
Then I checked the dictionary
UK strong /ɪz/ weak /z/ /s/ US strong /ɪz/ weak /z/ /s/
So I guessed that there is no contraction in the sentence "it is on the table", people pronounce it as "ɪt zɑːn ðə ˈteɪbl" and /z/ is the weak form of "is".
did I guess right?
