I speak some odd American Midwestern language where "crayon" is pronounced "cran", milk is "melk" and double t's in words are disregarded in pronunciation.
Wait, that's not how crayon is supposed to be pronounced?
Also, the double tt thing (if you are referring to "kitten", "mitten", etc.) is common throughout the language. It has a special name; I learned it in a linguistics class. I feel smart.
