I dunno why, but I see Sina having a soft T, when she speaks. If that’s the right term to call it. Basically, her Ts sound almost silent if it’s in the middle of a word or name.
There are some exceptions:
Milfanito will always have that hard T, r any other words that have the T towards the beginning or end of the name. That T has to be in the middle. Names that have combined contestants with T (such as OrnSTein) would have the T pronounced as well.
