In linked words, flapped T is pronounced such as (what if).
Flapped T is pronounced when the T comes between two vowels.
According to the previous rules, I expect to pronounce the flapped T in the phrase (...rate our...). When I asked a native speaker, he answered that the T isn't flapped.
I still don't know why? And is the word (rate) a special case so we never flap the T in any phrase like (rate a service - rate it - rate or ...etc.)
