This is a distinction in consonants! Different realizations of the /t/ phoneme. The whole claim that started this thread was that English expresses information almost exclusively in consonants, not vowels. Your example directly contradicts that very claim.

Anyway, English is _far_ from the only language where different dialects have a different set of vowels. Quebec French for example has completely different ones from French French.
